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 | |

84 | ;; verilog-auto-* functions for some major coding time savers. | |

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 |

91 | ;; should be common across all users (in a site-start file), or set | |

2991 | Variables controlling indentation/edit style: | |
2992 | ||
2993 | variable `verilog-indent-level' (default 3) | |
2994 | Indentation of Verilog statements with respect to containing block. | |
2995 | `verilog-indent-level-module' (default 3) | |
2996 | Absolute indentation of Module level Verilog statements. | |
2997 | Set to 0 to get initial and always statements lined up | |
2998 | on the left side of your screen. | |
2999 | `verilog-indent-level-declaration' (default 3) | |
3000 | Indentation of declarations with respect to containing block. | |
3001 | Set to 0 to get them list right under containing block. | |
3002 | `verilog-indent-level-behavioral' (default 3) | |
3003 | Indentation of first begin in a task or function block | |
37ea4b9b JB |
3004 | Set to 0 to get such code to lined up underneath the task or |
3005 | function keyword. | |
6341f357 | 3006 | `verilog-indent-level-directive' (default 1) |
37ea4b9b | 3007 | Indentation of `ifdef/`endif blocks. |
6341f357 DN |
3008 | `verilog-cexp-indent' (default 1) |
3009 | Indentation of Verilog statements broken across lines i.e.: | |
3010 | if (a) | |
3011 | begin | |
3012 | `verilog-case-indent' (default 2) | |
3013 | Indentation for case statements. | |
3014 | `verilog-auto-newline' (default nil) | |
3015 | Non-nil means automatically newline after semicolons and the punctuation | |
3016 | mark after an end. | |
3017 | `verilog-auto-indent-on-newline' (default t) | |
37ea4b9b | 3018 | Non-nil means automatically indent line after newline. |
6341f357 DN |
3019 | `verilog-tab-always-indent' (default t) |
3020 | Non-nil means TAB in Verilog mode should always reindent the current line, | |
3021 | regardless of where in the line point is when the TAB command is used. | |
3022 | `verilog-indent-begin-after-if' (default t) | |
3023 | Non-nil means to indent begin statements following a preceding | |
37ea4b9b | 3024 | if, else, while, for and repeat statements, if any. Otherwise, |
6341f357 DN |
3025 | the begin is lined up with the preceding token. If t, you get: |
3026 | if (a) | |
3027 | begin // amount of indent based on `verilog-cexp-indent' | |
3028 | otherwise you get: | |
3029 | if (a) | |
3030 | begin | |
3031 | `verilog-auto-endcomments' (default t) | |
3032 | Non-nil means a comment /* ... */ is set after the ends which ends | |
3033 | cases, tasks, functions and modules. | |
3034 | The type and name of the object will be set between the braces. | |
3035 | `verilog-minimum-comment-distance' (default 10) | |
3036 | Minimum distance (in lines) between begin and end required before a comment | |
3037 | will be inserted. Setting this variable to zero results in every | |
3038 | end acquiring a comment; the default avoids too many redundant | |
3039 | comments in tight quarters. | |
a3a8b002 | 3040 | `verilog-auto-lineup' (default 'declarations) |
6341f357 DN |

9598 | by changing the variable `verilog-library-flags' or | |
9599 | `verilog-library-directories'. Macros `modname are translated through the | |
9600 | vh-{name} Emacs variable, if that is not found, it just ignores the `. | |
9601 | ||
9602 | In templates you must have one signal per line, ending in a ), or ));, | |
9603 | and have proper () nesting, including a final ); to end the template. | |
9604 | ||
9605 | Typedefs must match `verilog-typedef-regexp', which is disabled by default. | |
9606 | ||
37ea4b9b | 9607 | SystemVerilog multidimensional input/output has only experimental support. |
6341f357 | 9608 | |
a03c2342 WS |
9609 | SystemVerilog .name syntax is used if `verilog-auto-inst-dot-name' is set. |
9610 | ||
4c5e69c6 DN |
9611 | Parameters referenced by the instantiation will remain symbolic, unless |
9612 | `verilog-auto-inst-param-value' is set. | |
9613 | ||
a03c2342 WS |
9614 | Gate primitives (and/or) may have AUTOINST for the purpose of |
9615 | AUTOWIRE declarations, etc. Gates are the only case when | |
9616 | position based connections are passed. | |
9617 | ||
1dd4b004 | 9618 | For example, first take the submodule InstModule.v: |
6341f357 | 9619 | |
a03c2342 | 9620 | module InstModule (o,i); |
6341f357 DN |
9621 | output [31:0] o; |
9622 | input i; | |
9623 | wire [31:0] o = {32{i}}; | |
9624 | endmodule | |
9625 | ||
9626 | This is then used in a upper level module: | |
9627 | ||
a03c2342 | 9628 | module ExampInst (o,i); |
6341f357 DN |
9629 | output o; |
9630 | input i; | |
1dd4b004 DN |
9631 | InstModule instName |
9632 | (/*AUTOINST*/); | |
6341f357 DN |
9633 | endmodule |
9634 | ||
9635 | Typing \\[verilog-auto] will make this into: | |
9636 | ||
a03c2342 | 9637 | module ExampInst (o,i); |
6341f357 DN |
9638 | output o; |
9639 | input i; | |
1dd4b004 DN |
9640 | InstModule instName |
9641 | (/*AUTOINST*/ | |
9642 | // Outputs | |
9643 | .ov (ov[31:0]), | |
9644 | // Inputs | |
9645 | .i (i)); | |
6341f357 DN |
9646 | endmodule |
9647 | ||
9648 | Where the list of inputs and outputs came from the inst module. | |
9649 | \f | |
9650 | Exceptions: | |
9651 | ||
9652 | Unless you are instantiating a module multiple times, or the module is | |
37ea4b9b | 9653 | something trivial like an adder, DO NOT CHANGE SIGNAL NAMES ACROSS HIERARCHY. |
6341f357 | 9654 | It just makes for unmaintainable code. To sanitize signal names, try |
855b42a2 | 9655 | vrename from URL `http://www.veripool.org'. |
6341f357 DN |
9656 | |
9657 | When you need to violate this suggestion there are two ways to list | |
9658 | exceptions, placing them before the AUTOINST, or using templates. | |
9659 | ||
9660 | Any ports defined before the /*AUTOINST*/ are not included in the list of | |
9661 | automatics. This is similar to making a template as described below, but | |
9662 | is restricted to simple connections just like you normally make. Also note | |
9663 | that any signals before the AUTOINST will only be picked up by AUTOWIRE if | |
9664 | you have the appropriate // Input or // Output comment, and exactly the | |
9665 | same line formatting as AUTOINST itself uses. | |
9666 | ||
1dd4b004 DN |
9667 | InstModule instName |
9668 | (// Inputs | |
9669 | .i (my_i_dont_mess_with_it), | |
9670 | /*AUTOINST*/ | |
9671 | // Outputs | |
9672 | .ov (ov[31:0])); | |
6341f357 DN |
9673 | |
9674 | \f | |
9675 | Templates: | |
9676 | ||
9677 | For multiple instantiations based upon a single template, create a | |
9678 | commented out template: | |
9679 | ||
1dd4b004 | 9680 | /* InstModule AUTO_TEMPLATE ( |
6341f357 DN |
9681 | .sig3 (sigz[]), |
9682 | ); | |
9683 | */ | |
9684 | ||
37ea4b9b | 9685 | Templates go ABOVE the instantiation(s). When an instantiation is |
6341f357 DN |
9686 | expanded `verilog-mode' simply searches up for the closest template. |
9687 | Thus you can have multiple templates for the same module, just alternate | |
37ea4b9b | 9688 | between the template for an instantiation and the instantiation itself. |
6341f357 DN |
9689 | |
9690 | The module name must be the same as the name of the module in the | |
9691 | instantiation name, and the code \"AUTO_TEMPLATE\" must be in these exact | |
9692 | words and capitalized. Only signals that must be different for each | |
9693 | instantiation need to be listed. | |
9694 | ||
9695 | Inside a template, a [] in a connection name (with nothing else inside | |
9696 | the brackets) will be replaced by the same bus subscript as it is being | |
9697 | connected to, or the [] will be removed if it is a single bit signal. | |
9698 | Generally it is a good idea to do this for all connections in a template, | |
9699 | as then they will work for any width signal, and with AUTOWIRE. See | |
9700 | PTL_BUS becoming PTL_BUSNEW below. | |
9701 | ||
9702 | If you have a complicated template, set `verilog-auto-inst-template-numbers' | |
9703 | to see which regexps are matching. Don't leave that mode set after | |
9704 | debugging is completed though, it will result in lots of extra differences | |
9705 | and merge conflicts. | |
9706 | ||
9707 | For example: | |
9708 | ||
1dd4b004 | 9709 | /* InstModule AUTO_TEMPLATE ( |
6341f357 DN |
9710 | .ptl_bus (ptl_busnew[]), |
9711 | ); | |
9712 | */ | |
1dd4b004 | 9713 | InstModule ms2m (/*AUTOINST*/); |
6341f357 DN |
9714 | |
9715 | Typing \\[verilog-auto] will make this into: | |
9716 | ||
1dd4b004 | 9717 | InstModule ms2m (/*AUTOINST*/ |
6341f357 DN |
9718 | // Outputs |
9719 | .NotInTemplate (NotInTemplate), | |
9720 | .ptl_bus (ptl_busnew[3:0]), // Templated | |
9721 | .... | |
9722 | \f | |
9723 | @ Templates: | |
9724 | ||
9725 | It is common to instantiate a cell multiple times, so templates make it | |
9726 | trivial to substitute part of the cell name into the connection name. | |
9727 | ||
1dd4b004 | 9728 | /* InstName AUTO_TEMPLATE <optional \"REGEXP\"> ( |
6341f357 DN |
9729 | .sig1 (sigx[@]), |
9730 | .sig2 (sigy[@\"(% (+ 1 @) 4)\"]), | |
9731 | ); | |
9732 | */ | |
9733 | ||
9734 | If no regular expression is provided immediately after the AUTO_TEMPLATE | |
9735 | keyword, then the @ character in any connection names will be replaced | |
9736 | with the instantiation number; the first digits found in the cell's | |
9737 | instantiation name. | |
9738 | ||
9739 | If a regular expression is provided, the @ character will be replaced | |
9740 | with the first \(\) grouping that matches against the cell name. Using a | |
9741 | regexp of \"\\([0-9]+\\)\" provides identical values for @ as when no | |
9742 | regexp is provided. If you use multiple layers of parenthesis, | |
9743 | \"test\\([^0-9]+\\)_\\([0-9]+\\)\" would replace @ with non-number | |
9744 | characters after test and before _, whereas | |
9745 | \"\\(test\\([a-z]+\\)_\\([0-9]+\\)\\)\" would replace @ with the entire | |
9746 | match. | |
9747 | ||
9748 | For example: | |
9749 | ||
1dd4b004 | 9750 | /* InstModule AUTO_TEMPLATE ( |
6341f357 DN |
9751 | .ptl_mapvalidx (ptl_mapvalid[@]), |
9752 | .ptl_mapvalidp1x (ptl_mapvalid[@\"(% (+ 1 @) 4)\"]), | |
9753 | ); | |
9754 | */ | |
1dd4b004 | 9755 | InstModule ms2m (/*AUTOINST*/); |
6341f357 DN |
9756 | |
9757 | Typing \\[verilog-auto] will make this into: | |
9758 | ||
1dd4b004 | 9759 | InstModule ms2m (/*AUTOINST*/ |
6341f357 DN |
9760 | // Outputs |
9761 | .ptl_mapvalidx (ptl_mapvalid[2]), | |
9762 | .ptl_mapvalidp1x (ptl_mapvalid[3])); | |
9763 | ||
9764 | Note the @ character was replaced with the 2 from \"ms2m\". | |
9765 | ||
9766 | Alternatively, using a regular expression for @: | |
9767 | ||
1dd4b004 | 9768 | /* InstModule AUTO_TEMPLATE \"_\\([a-z]+\\)\" ( |
6341f357 DN |
9769 | .ptl_mapvalidx (@_ptl_mapvalid), |
9770 | .ptl_mapvalidp1x (ptl_mapvalid_@), | |
9771 | ); | |
9772 | */ | |
1dd4b004 DN |
9773 | InstModule ms2_FOO (/*AUTOINST*/); |
9774 | InstModule ms2_BAR (/*AUTOINST*/); | |
6341f357 DN |
9775 | |
9776 | Typing \\[verilog-auto] will make this into: | |
9777 | ||
1dd4b004 | 9778 | InstModule ms2_FOO (/*AUTOINST*/ |
6341f357 DN |
9779 | // Outputs |
9780 | .ptl_mapvalidx (FOO_ptl_mapvalid), | |
9781 | .ptl_mapvalidp1x (ptl_mapvalid_FOO)); | |
1dd4b004 | 9782 | InstModule ms2_BAR (/*AUTOINST*/ |
6341f357 DN |
9783 | // Outputs |
9784 | .ptl_mapvalidx (BAR_ptl_mapvalid), | |
9785 | .ptl_mapvalidp1x (ptl_mapvalid_BAR)); | |
9786 | ||
9787 | \f | |
9788 | Regexp Templates: | |
9789 | ||
9790 | A template entry of the form | |
9791 | ||
9792 | .pci_req\\([0-9]+\\)_l (pci_req_jtag_[\\1]), | |
9793 | ||
37ea4b9b | 9794 | will apply an Emacs style regular expression search for any port beginning |
6341f357 DN |
9795 | in pci_req followed by numbers and ending in _l and connecting that to |
9796 | the pci_req_jtag_[] net, with the bus subscript coming from what matches | |
9797 | inside the first set of \\( \\). Thus pci_req2_l becomes pci_req_jtag_[2]. | |
9798 | ||
9799 | Since \\([0-9]+\\) is so common and ugly to read, a @ in the port name | |
0e5c8aed | 9800 | does the same thing. (Note a @ in the connection/replacement text is |
6341f357 DN |
9801 | completely different -- still use \\1 there!) Thus this is the same as |
9802 | the above template: | |
9803 | ||
9804 | .pci_req@_l (pci_req_jtag_[\\1]), | |
9805 | ||
9806 | Here's another example to remove the _l, useful when naming conventions | |
9807 | specify _ alone to mean active low. Note the use of [] to keep the bus | |
9808 | subscript: | |
9809 | ||
9810 | .\\(.*\\)_l (\\1_[]), | |
9811 | \f | |
9812 | Lisp Templates: | |
9813 | ||
9814 | First any regular expression template is expanded. | |
9815 | ||
9816 | If the syntax @\"( ... )\" is found in a connection, the expression in | |
9817 | quotes will be evaluated as a Lisp expression, with @ replaced by the | |
9818 | instantiation number. The MAPVALIDP1X example above would put @+1 modulo | |
9819 | 4 into the brackets. Quote all double-quotes inside the expression with | |
0e5c8aed DN |
9820 | a leading backslash (\\\"...\\\"); or if the Lisp template is also a |
9821 | regexp template backslash the backslash quote (\\\\\"...\\\\\"). | |
9822 | ||
9823 | There are special variables defined that are useful in these | |
9824 | Lisp functions: | |
6341f357 | 9825 | |
37ea4b9b JB |
9826 | vl-name Name portion of the input/output port. |
9827 | vl-bits Bus bits portion of the input/output port ('[2:0]'). | |
fd9ea9d3 | 9828 | vl-mbits Multidimensional array bits for port ('[2:0][3:0]'). |
37ea4b9b | 9829 | vl-width Width of the input/output port ('3' for [2:0]). |
6341f357 | 9830 | May be a (...) expression if bits isn't a constant. |
a3a8b002 DN |
9831 | vl-dir Direction of the pin input/output/inout/interface. |
9832 | vl-modport The modport, if an interface with a modport. | |
1dd4b004 DN |
9833 | vl-cell-type Module name/type of the cell ('InstModule'). |
9834 | vl-cell-name Instance name of the cell ('instName'). | |
6341f357 DN |
9835 | |
9836 | Normal Lisp variables may be used in expressions. See | |
9837 | `verilog-read-defines' which can set vh-{definename} variables for use | |
9838 | here. Also, any comments of the form: | |
9839 | ||
9840 | /*AUTO_LISP(setq foo 1)*/ | |
9841 | ||
9842 | will evaluate any Lisp expression inside the parenthesis between the | |
9843 | beginning of the buffer and the point of the AUTOINST. This allows | |
9844 | functions to be defined or variables to be changed between instantiations. | |
a3a8b002 DN |
9845 | (See also `verilog-auto-insert-lisp' if you want the output from your |
9846 | lisp function to be inserted.) | |
6341f357 DN |
9847 | |
9848 | Note that when using lisp expressions errors may occur when @ is not a | |
37ea4b9b | 9849 | number; you may need to use the standard Emacs Lisp functions |
6341f357 DN |
9850 | `number-to-string' and `string-to-number'. |
9851 | ||
9852 | After the evaluation is completed, @ substitution and [] substitution | |
0e5c8aed DN |
9853 | occur. |

10791 | placed into the sensitivity list (see `verilog-auto-sense-include-inputs'). | |
10792 | Long lines are split based on the `fill-column', see \\[set-fill-column]. | |
10793 | ||
10794 | Limitations: | |
10795 | Verilog does not allow memories (multidimensional arrays) in sensitivity | |
10796 | lists. AUTOSENSE will thus exclude them, and add a /*memory or*/ comment. | |
10797 | ||
10798 | Constant signals: | |
10799 | AUTOSENSE cannot always determine if a `define is a constant or a signal | |
10800 | (it could be in a include file for example). If a `define or other signal | |
10801 | is put into the AUTOSENSE list and is not desired, use the AUTO_CONSTANT | |
10802 | declaration anywhere in the module (parenthesis are required): | |
10803 | ||
10804 | /* AUTO_CONSTANT ( `this_is_really_constant_dont_autosense_it ) */ | |
10805 | ||
10806 | Better yet, use a parameter, which will be understood to be constant | |
10807 | automatically. | |
10808 | ||
10809 | OOps! | |
10810 | If AUTOSENSE makes a mistake, please report it. (First try putting | |
10811 | a begin/end after your always!) As a workaround, if a signal that | |
10812 | shouldn't be in the sensitivity list was, use the AUTO_CONSTANT above. | |
10813 | If a signal should be in the sensitivity list wasn't, placing it before | |
10814 | the /*AUTOSENSE*/ comment will prevent it from being deleted when the | |
10815 | autos are updated (or added if it occurs there already). | |
10816 | ||
10817 | An example: | |
10818 | ||
1dd4b004 | 10819 | always @ (/*AS*/) begin |
6341f357 DN |
10820 | /* AUTO_CONSTANT (`constant) */ |

11072 | with \"unused\" in the signal name. | |
11073 | ||
11074 | To reduce simulation time, the _unused_ok signal should be forced to a | |

11146 | Create a register to contain the ASCII decode of a enumerated signal type. | |
11147 | This will allow trace viewers to show the ASCII name of states. | |
11148 | ||
11149 | First, parameters are built into a enumeration using the synopsys enum | |
11150 | comment. The comment must be between the keyword and the symbol. | |
6edb5716 | 11151 | \(Annoying, but that's what Synopsys's dc_shell FSM reader requires.) |
6341f357 DN |
11152 | |
11153 | Next, registers which that enum applies to are also tagged with the same | |
11154 | enum. Synopsys also suggests labeling state vectors, but `verilog-mode' | |
11155 | doesn't care. | |
11156 | ||
11157 | Finally, a AUTOASCIIENUM command is used. | |
11158 | ||
11159 | The first parameter is the name of the signal to be decoded. | |
a3a8b002 DN |
11160 | If and only if the first parameter width is 2^(number of states |
11161 | in enum) and does NOT match the width of the enum, the signal | |
11162 | is assumed to be a one hot decode. Otherwise, it's a normal | |
11163 | encoded state vector. | |
6341f357 DN |
11164 | |
11165 | The second parameter is the name to store the ASCII code into. For the | |
11166 | signal foo, I suggest the name _foo__ascii, where the leading _ indicates | |
11167 | a signal that is just for simulation, and the magic characters _ascii | |
11168 | tell viewers like Dinotrace to display in ASCII format. | |
11169 | ||

86a4c7ac | 12084 | I want to report a bug. |
6341f357 DN |
12085 | |
12086 | Before I go further, I want to say that Verilog mode has changed my life. | |
12087 | I save so much time, my files are colored nicely, my co workers respect | |
12088 | my coding ability... until now. I'd really appreciate anything you | |
12089 | could do to help me out with this minor deficiency in the product. | |
12090 | ||
86a4c7ac | 12091 | I've taken a look at the Verilog-Mode FAQ at |
7cb1c4d7 | 12092 | http://www.veripool.org/verilog-mode-faq.html. |
6341f357 | 12093 | |
86a4c7ac DN |
12094 | And, I've considered filing the bug on the issue tracker at |
12095 | http://www.veripool.org/verilog-mode-bugs | |
12096 | since I realize that public bugs are easier for you to track, | |
12097 | and for others to search, but would prefer to email. | |
12098 | ||
12099 | So, to reproduce the bug, start a fresh Emacs via " invocation-name " | |
37ea4b9b | 12100 | -no-init-file -no-site-file'. In a new buffer, in Verilog mode, type |
6341f357 DN |
12101 | the code included below. |
12102 | ||
12103 | Given those lines, I expected [[Fill in here]] to happen; | |
12104 | but instead, [[Fill in here]] happens!. | |
12105 | ||
12106 | == The code: ==")))) | |
