43 | ;; USAGE | |
44 | ;; ===== | |
45 | ||
60618039 | 46 | ;; A major mode for editing Verilog HDL source code. When you have |
6341f357 DN |
47 | ;; entered Verilog mode, you may get more info by pressing C-h m. You |
48 | ;; may also get online help describing various functions by: C-h f | |
49 | ;; <Name of function you want described> | |
50 | ||
51 | ;; KNOWN BUGS / BUG REPORTS | |
52 | ;; ======================= | |
53 | ||
54 | ;; Verilog is a rapidly evolving language, and hence this mode is | |
60618039 | 55 | ;; under continuous development. Hence this is beta code, and likely |
a3a8b002 DN |
56 | ;; has bugs. Please report any issues to the issue tracker at |
57 | ;; http://www.veripool.org/verilog-mode | |
6341f357 DN |
58 | ;; Please use verilog-submit-bug-report to submit a report; type C-c |
59 | ;; C-b to invoke this and as a result I will have a much easier time | |
60 | ;; of reproducing the bug you find, and hence fixing it. | |
61 | ||
62 | ;; INSTALLING THE MODE | |
63 | ;; =================== | |
64 | ||
65 | ;; An older version of this mode may be already installed as a part of | |
66 | ;; your environment, and one method of updating would be to update | |
60618039 | 67 | ;; your Emacs environment. Sometimes this is difficult for local |
6341f357 DN |
68 | ;; political/control reasons, and hence you can always install a |
69 | ;; private copy (or even a shared copy) which overrides the system | |
70 | ;; default. | |
71 | ||
72 | ;; You can get step by step help in installing this file by going to | |
73 | ;; <http://www.verilog.com/emacs_install.html> | |
74 | ||
75 | ;; The short list of installation instructions are: To set up | |
37ea4b9b | 76 | ;; automatic Verilog mode, put this file in your load path, and put |
6341f357 DN |
77 | ;; the following in code (please un comment it first!) in your |
78 | ;; .emacs, or in your site's site-load.el | |

83 | ;; Be sure to examine at the help for verilog-auto, and the other |
84 | ;; verilog-auto-* functions for some major coding time savers. | |
85 | ;; | |
6341f357 | 86 | ;; If you want to customize Verilog mode to fit your needs better, |
a03c2342 | 87 | ;; you may add the below lines (the values of the variables presented |
60618039 | 88 | ;; here are the defaults). Note also that if you use an Emacs that |
6341f357 | 89 | ;; supports custom, it's probably better to use the custom menu to |

a03c2342 WS |
91 | ;; should be common across all users (in a site-start file), or set |
92 | ;; in Local Variables in every file. Otherwise, different people's | |

3422 | Indentation of Verilog statements with respect to containing block. | |
3423 | `verilog-indent-level-module' (default 3) | |
3424 | Absolute indentation of Module level Verilog statements. | |
3425 | Set to 0 to get initial and always statements lined up | |
3426 | on the left side of your screen. | |
3427 | `verilog-indent-level-declaration' (default 3) | |
3428 | Indentation of declarations with respect to containing block. | |
3429 | Set to 0 to get them list right under containing block. | |
3430 | `verilog-indent-level-behavioral' (default 3) | |
3431 | Indentation of first begin in a task or function block | |
37ea4b9b JB |
3432 | Set to 0 to get such code to lined up underneath the task or |
3433 | function keyword. | |
6341f357 | 3434 | `verilog-indent-level-directive' (default 1) |
37ea4b9b | 3435 | Indentation of `ifdef/`endif blocks. |
6341f357 DN |
3436 | `verilog-cexp-indent' (default 1) |
3437 | Indentation of Verilog statements broken across lines i.e.: | |
3438 | if (a) | |
3439 | begin | |
3440 | `verilog-case-indent' (default 2) | |
3441 | Indentation for case statements. | |
3442 | `verilog-auto-newline' (default nil) | |
3443 | Non-nil means automatically newline after semicolons and the punctuation | |
3444 | mark after an end. | |
3445 | `verilog-auto-indent-on-newline' (default t) | |
37ea4b9b | 3446 | Non-nil means automatically indent line after newline. |
6341f357 DN |
3447 | `verilog-tab-always-indent' (default t) |
3448 | Non-nil means TAB in Verilog mode should always reindent the current line, | |
3449 | regardless of where in the line point is when the TAB command is used. | |
3450 | `verilog-indent-begin-after-if' (default t) | |
3451 | Non-nil means to indent begin statements following a preceding | |
37ea4b9b | 3452 | if, else, while, for and repeat statements, if any. Otherwise, |
6341f357 DN |
3453 | the begin is lined up with the preceding token. If t, you get: |
3454 | if (a) | |

3456 | otherwise you get: | |
3457 | if (a) | |
3458 | begin | |
3459 | `verilog-auto-endcomments' (default t) | |
3460 | Non-nil means a comment /* ... */ is set after the ends which ends | |
3461 | cases, tasks, functions and modules. | |
3462 | The type and name of the object will be set between the braces. | |
3463 | `verilog-minimum-comment-distance' (default 10) | |
3464 | Minimum distance (in lines) between begin and end required before a comment | |
3465 | will be inserted. Setting this variable to zero results in every | |
3466 | end acquiring a comment; the default avoids too many redundant | |
3467 | comments in tight quarters. | |
a3a8b002 | 3468 | `verilog-auto-lineup' (default 'declarations) |
6341f357 DN |

10344 | by changing the variable `verilog-library-flags' or | |
10345 | `verilog-library-directories'. Macros `modname are translated through the | |
10346 | vh-{name} Emacs variable, if that is not found, it just ignores the `. | |
10347 | ||
10348 | In templates you must have one signal per line, ending in a ), or ));, | |
10349 | and have proper () nesting, including a final ); to end the template. | |
10350 | ||
10351 | Typedefs must match `verilog-typedef-regexp', which is disabled by default. | |
10352 | ||
37ea4b9b | 10353 | SystemVerilog multidimensional input/output has only experimental support. |
6341f357 | 10354 | |
a03c2342 WS |
10355 | SystemVerilog .name syntax is used if `verilog-auto-inst-dot-name' is set. |
10356 | ||
4c5e69c6 DN |
10357 | Parameters referenced by the instantiation will remain symbolic, unless |
10358 | `verilog-auto-inst-param-value' is set. | |
10359 | ||
a03c2342 WS |
10360 | Gate primitives (and/or) may have AUTOINST for the purpose of |
10361 | AUTOWIRE declarations, etc. Gates are the only case when | |
10362 | position based connections are passed. | |
10363 | ||
1dd4b004 | 10364 | For example, first take the submodule InstModule.v: |
6341f357 | 10365 | |
a03c2342 | 10366 | module InstModule (o,i); |
6341f357 DN |
10367 | output [31:0] o; |
10368 | input i; | |
10369 | wire [31:0] o = {32{i}}; | |
10370 | endmodule | |
10371 | ||
10372 | This is then used in a upper level module: | |
10373 | ||
a03c2342 | 10374 | module ExampInst (o,i); |
6341f357 DN |
10375 | output o; |
10376 | input i; | |
1dd4b004 DN |
10377 | InstModule instName |
10378 | (/*AUTOINST*/); | |
6341f357 DN |
10379 | endmodule |
10380 | ||
10381 | Typing \\[verilog-auto] will make this into: | |
10382 | ||
a03c2342 | 10383 | module ExampInst (o,i); |
6341f357 DN |
10384 | output o; |
10385 | input i; | |
1dd4b004 DN |
10386 | InstModule instName |
10387 | (/*AUTOINST*/ | |
10388 | // Outputs | |
10389 | .ov (ov[31:0]), | |
10390 | // Inputs | |
10391 | .i (i)); | |
6341f357 DN |
10392 | endmodule |
10393 | ||
10394 | Where the list of inputs and outputs came from the inst module. | |
10395 | \f | |
10396 | Exceptions: | |
10397 | ||
10398 | Unless you are instantiating a module multiple times, or the module is | |
37ea4b9b | 10399 | something trivial like an adder, DO NOT CHANGE SIGNAL NAMES ACROSS HIERARCHY. |
6341f357 | 10400 | It just makes for unmaintainable code. To sanitize signal names, try |
855b42a2 | 10401 | vrename from URL `http://www.veripool.org'. |
6341f357 DN |
10402 | |
10403 | When you need to violate this suggestion there are two ways to list | |
10404 | exceptions, placing them before the AUTOINST, or using templates. | |
10405 | ||
10406 | Any ports defined before the /*AUTOINST*/ are not included in the list of | |
10407 | automatics. This is similar to making a template as described below, but | |
10408 | is restricted to simple connections just like you normally make. Also note | |
10409 | that any signals before the AUTOINST will only be picked up by AUTOWIRE if | |
10410 | you have the appropriate // Input or // Output comment, and exactly the | |
10411 | same line formatting as AUTOINST itself uses. | |
10412 | ||
1dd4b004 DN |
10413 | InstModule instName |
10414 | (// Inputs | |
10415 | .i (my_i_dont_mess_with_it), | |
10416 | /*AUTOINST*/ | |
10417 | // Outputs | |
10418 | .ov (ov[31:0])); | |
6341f357 DN |
10419 | |
10420 | \f | |
10421 | Templates: | |
10422 | ||
10423 | For multiple instantiations based upon a single template, create a | |
10424 | commented out template: | |
10425 | ||
1dd4b004 | 10426 | /* InstModule AUTO_TEMPLATE ( |
6341f357 DN |
10427 | .sig3 (sigz[]), |
10428 | ); | |
10429 | */ | |
10430 | ||
37ea4b9b | 10431 | Templates go ABOVE the instantiation(s). When an instantiation is |
6341f357 DN |
10432 | expanded `verilog-mode' simply searches up for the closest template. |
10433 | Thus you can have multiple templates for the same module, just alternate | |
37ea4b9b | 10434 | between the template for an instantiation and the instantiation itself. |
6341f357 DN |
10435 | |
10436 | The module name must be the same as the name of the module in the | |
10437 | instantiation name, and the code \"AUTO_TEMPLATE\" must be in these exact | |
10438 | words and capitalized. Only signals that must be different for each | |
10439 | instantiation need to be listed. | |
10440 | ||
10441 | Inside a template, a [] in a connection name (with nothing else inside | |
10442 | the brackets) will be replaced by the same bus subscript as it is being | |
10443 | connected to, or the [] will be removed if it is a single bit signal. | |
10444 | Generally it is a good idea to do this for all connections in a template, | |
10445 | as then they will work for any width signal, and with AUTOWIRE. See | |
10446 | PTL_BUS becoming PTL_BUSNEW below. | |
10447 | ||
10448 | If you have a complicated template, set `verilog-auto-inst-template-numbers' | |
10449 | to see which regexps are matching. Don't leave that mode set after | |
10450 | debugging is completed though, it will result in lots of extra differences | |
10451 | and merge conflicts. | |
10452 | ||
10453 | For example: | |
10454 | ||
1dd4b004 | 10455 | /* InstModule AUTO_TEMPLATE ( |
6341f357 DN |
10456 | .ptl_bus (ptl_busnew[]), |
10457 | ); | |
10458 | */ | |
1dd4b004 | 10459 | InstModule ms2m (/*AUTOINST*/); |
6341f357 DN |
10460 | |
10461 | Typing \\[verilog-auto] will make this into: | |
10462 | ||
1dd4b004 | 10463 | InstModule ms2m (/*AUTOINST*/ |
6341f357 DN |
10464 | // Outputs |
10465 | .NotInTemplate (NotInTemplate), | |
10466 | .ptl_bus (ptl_busnew[3:0]), // Templated | |
10467 | .... | |
9489a450 MM |
10468 | |
10469 | \f | |
10470 | Multiple Module Templates: | |
10471 | ||
10472 | The same template lines can be applied to multiple modules with | |
10473 | the syntax as follows: | |
10474 | ||
10475 | /* InstModuleA AUTO_TEMPLATE | |
10476 | InstModuleB AUTO_TEMPLATE | |
10477 | InstModuleC AUTO_TEMPLATE | |
10478 | InstModuleD AUTO_TEMPLATE ( | |
10479 | .ptl_bus (ptl_busnew[]), | |
10480 | ); | |
10481 | */ | |
10482 | ||
10483 | Note there is only one AUTO_TEMPLATE opening parenthesis. | |
6341f357 DN |
10484 | \f |
10485 | @ Templates: | |
10486 | ||
10487 | It is common to instantiate a cell multiple times, so templates make it | |
10488 | trivial to substitute part of the cell name into the connection name. | |
10489 | ||
1dd4b004 | 10490 | /* InstName AUTO_TEMPLATE <optional \"REGEXP\"> ( |
6341f357 DN |
10491 | .sig1 (sigx[@]), |
10492 | .sig2 (sigy[@\"(% (+ 1 @) 4)\"]), | |
10493 | ); | |
10494 | */ | |
10495 | ||
10496 | If no regular expression is provided immediately after the AUTO_TEMPLATE | |
10497 | keyword, then the @ character in any connection names will be replaced | |
10498 | with the instantiation number; the first digits found in the cell's | |
10499 | instantiation name. | |
10500 | ||
10501 | If a regular expression is provided, the @ character will be replaced | |
10502 | with the first \(\) grouping that matches against the cell name. Using a | |
10503 | regexp of \"\\([0-9]+\\)\" provides identical values for @ as when no | |
10504 | regexp is provided. If you use multiple layers of parenthesis, | |
10505 | \"test\\([^0-9]+\\)_\\([0-9]+\\)\" would replace @ with non-number | |
10506 | characters after test and before _, whereas | |
10507 | \"\\(test\\([a-z]+\\)_\\([0-9]+\\)\\)\" would replace @ with the entire | |
10508 | match. | |
10509 | ||
10510 | For example: | |
10511 | ||
1dd4b004 | 10512 | /* InstModule AUTO_TEMPLATE ( |
6341f357 DN |
10513 | .ptl_mapvalidx (ptl_mapvalid[@]), |
10514 | .ptl_mapvalidp1x (ptl_mapvalid[@\"(% (+ 1 @) 4)\"]), | |
10515 | ); | |
10516 | */ | |

10550 | Regexp Templates: | |
10551 | ||
10552 | A template entry of the form | |
10553 | ||
10554 | .pci_req\\([0-9]+\\)_l (pci_req_jtag_[\\1]), | |
10555 | ||
37ea4b9b | 10556 | will apply an Emacs style regular expression search for any port beginning |
6341f357 DN |
10557 | in pci_req followed by numbers and ending in _l and connecting that to |
10558 | the pci_req_jtag_[] net, with the bus subscript coming from what matches | |
10559 | inside the first set of \\( \\). Thus pci_req2_l becomes pci_req_jtag_[2]. | |
10560 | ||
10561 | Since \\([0-9]+\\) is so common and ugly to read, a @ in the port name | |
0e5c8aed | 10562 | does the same thing. (Note a @ in the connection/replacement text is |
6341f357 DN |
10563 | completely different -- still use \\1 there!) Thus this is the same as |
10564 | the above template: | |
10565 | ||
10566 | .pci_req@_l (pci_req_jtag_[\\1]), | |
10567 | ||
10568 | Here's another example to remove the _l, useful when naming conventions | |
10569 | specify _ alone to mean active low. Note the use of [] to keep the bus | |
10570 | subscript: | |
10571 | ||
10572 | .\\(.*\\)_l (\\1_[]), | |
10573 | \f | |
10574 | Lisp Templates: | |
10575 | ||
10576 | First any regular expression template is expanded. | |
10577 | ||
10578 | If the syntax @\"( ... )\" is found in a connection, the expression in | |
10579 | quotes will be evaluated as a Lisp expression, with @ replaced by the | |
10580 | instantiation number. The MAPVALIDP1X example above would put @+1 modulo | |
10581 | 4 into the brackets. Quote all double-quotes inside the expression with | |
0e5c8aed DN |
10582 | a leading backslash (\\\"...\\\"); or if the Lisp template is also a |
10583 | regexp template backslash the backslash quote (\\\\\"...\\\\\"). | |
10584 | ||
10585 | There are special variables defined that are useful in these | |
10586 | Lisp functions: | |
6341f357 | 10587 | |
37ea4b9b JB |
10588 | vl-name Name portion of the input/output port. |
10589 | vl-bits Bus bits portion of the input/output port ('[2:0]'). | |
fd9ea9d3 | 10590 | vl-mbits Multidimensional array bits for port ('[2:0][3:0]'). |
37ea4b9b | 10591 | vl-width Width of the input/output port ('3' for [2:0]). |
6341f357 | 10592 | May be a (...) expression if bits isn't a constant. |
a3a8b002 DN |
10593 | vl-dir Direction of the pin input/output/inout/interface. |
10594 | vl-modport The modport, if an interface with a modport. | |
1dd4b004 DN |
10595 | vl-cell-type Module name/type of the cell ('InstModule'). |
10596 | vl-cell-name Instance name of the cell ('instName'). | |
6341f357 DN |
10597 | |
10598 | Normal Lisp variables may be used in expressions. See | |
10599 | `verilog-read-defines' which can set vh-{definename} variables for use | |
10600 | here. Also, any comments of the form: | |
10601 | ||
10602 | /*AUTO_LISP(setq foo 1)*/ | |
10603 | ||
10604 | will evaluate any Lisp expression inside the parenthesis between the | |
10605 | beginning of the buffer and the point of the AUTOINST. This allows | |
10606 | functions to be defined or variables to be changed between instantiations. | |
a3a8b002 DN |
10607 | (See also `verilog-auto-insert-lisp' if you want the output from your |
10608 | lisp function to be inserted.) | |
6341f357 DN |
10609 | |
10610 | Note that when using lisp expressions errors may occur when @ is not a | |
37ea4b9b | 10611 | number; you may need to use the standard Emacs Lisp functions |
6341f357 DN |
10612 | `number-to-string' and `string-to-number'. |
10613 | ||
10614 | After the evaluation is completed, @ substitution and [] substitution | |
0e5c8aed DN |
10615 | occur. |

11609 | Replace the always (/*AUTOSENSE*/) sensitivity list (/*AS*/ for short) | |
11610 | with one automatically derived from all inputs declared in the always | |
11611 | statement. Signals that are generated within the same always block are NOT | |
11612 | placed into the sensitivity list (see `verilog-auto-sense-include-inputs'). | |
11613 | Long lines are split based on the `fill-column', see \\[set-fill-column]. | |
11614 | ||
11615 | Limitations: | |
11616 | Verilog does not allow memories (multidimensional arrays) in sensitivity | |
11617 | lists. AUTOSENSE will thus exclude them, and add a /*memory or*/ comment. | |
11618 | ||
11619 | Constant signals: | |
11620 | AUTOSENSE cannot always determine if a `define is a constant or a signal | |
11621 | (it could be in a include file for example). If a `define or other signal | |
11622 | is put into the AUTOSENSE list and is not desired, use the AUTO_CONSTANT | |
11623 | declaration anywhere in the module (parenthesis are required): | |
11624 | ||
11625 | /* AUTO_CONSTANT ( `this_is_really_constant_dont_autosense_it ) */ | |
11626 | ||
11627 | Better yet, use a parameter, which will be understood to be constant | |
11628 | automatically. | |
11629 | ||
11630 | OOps! | |
11631 | If AUTOSENSE makes a mistake, please report it. (First try putting | |
11632 | a begin/end after your always!) As a workaround, if a signal that | |
11633 | shouldn't be in the sensitivity list was, use the AUTO_CONSTANT above. | |
11634 | If a signal should be in the sensitivity list wasn't, placing it before | |
11635 | the /*AUTOSENSE*/ comment will prevent it from being deleted when the | |
11636 | autos are updated (or added if it occurs there already). | |
11637 | ||
11638 | An example: | |
11639 | ||
1dd4b004 | 11640 | always @ (/*AS*/) begin |
6341f357 DN |
11641 | /* AUTO_CONSTANT (`constant) */ |
11642 | outin = ina | inb | `constant; | |
11643 | out = outin; | |
11644 | end | |
11645 | ||

11978 | Create a register to contain the ASCII decode of a enumerated signal type. | |
11979 | This will allow trace viewers to show the ASCII name of states. | |
11980 | ||
11981 | First, parameters are built into a enumeration using the synopsys enum | |
11982 | comment. The comment must be between the keyword and the symbol. | |
6edb5716 | 11983 | \(Annoying, but that's what Synopsys's dc_shell FSM reader requires.) |
6341f357 DN |
11984 | |
11985 | Next, registers which that enum applies to are also tagged with the same | |
9489a450 | 11986 | enum. |
6341f357 DN |
11987 | |
11988 | Finally, a AUTOASCIIENUM command is used. | |
11989 | ||
11990 | The first parameter is the name of the signal to be decoded. | |
11991 | ||
11992 | The second parameter is the name to store the ASCII code into. For the | |
11993 | signal foo, I suggest the name _foo__ascii, where the leading _ indicates | |
11994 | a signal that is just for simulation, and the magic characters _ascii | |
11995 | tell viewers like Dinotrace to display in ASCII format. | |
11996 | ||
9489a450 MM |
11997 | The third optional parameter is a string which will be removed |
11998 | from the state names. It defaults to "" which removes nothing. | |
11999 | ||
12000 | The fourth optional parameter is \"onehot\" to force one-hot | |
12001 | decoding. If unspecified, if and only if the first parameter | |
12002 | width is 2^(number of states in enum) and does NOT match the | |
12003 | width of the enum, the signal is assumed to be a one hot | |
12004 | decode. Otherwise, it's a normal encoded state vector. | |
12005 | ||
12006 | `verilog-auto-wire-type' may be used to change the datatype of | |
12007 | the declarations. | |

86a4c7ac | 12972 | I want to report a bug. |
6341f357 DN |
12973 | |
12974 | Before I go further, I want to say that Verilog mode has changed my life. | |
12975 | I save so much time, my files are colored nicely, my co workers respect | |
12976 | my coding ability... until now. I'd really appreciate anything you | |
12977 | could do to help me out with this minor deficiency in the product. | |
12978 | ||
86a4c7ac | 12979 | I've taken a look at the Verilog-Mode FAQ at |
7cb1c4d7 | 12980 | http://www.veripool.org/verilog-mode-faq.html. |
6341f357 | 12981 | |
86a4c7ac DN |
12982 | And, I've considered filing the bug on the issue tracker at |
12983 | http://www.veripool.org/verilog-mode-bugs | |
12984 | since I realize that public bugs are easier for you to track, | |
12985 | and for others to search, but would prefer to email. | |
12986 | ||
12987 | So, to reproduce the bug, start a fresh Emacs via " invocation-name " | |
37ea4b9b | 12988 | -no-init-file -no-site-file'. In a new buffer, in Verilog mode, type |
6341f357 DN |
12989 | the code included below. |
12990 | ||
12991 | Given those lines, I expected [[Fill in here]] to happen; | |
12992 | but instead, [[Fill in here]] happens!. | |
12993 | ||
12994 | == The code: ==")))) | |
