SublimeLinter-contrib-verilator

Package Control Build Status PayPal

This linter plugin for SublimeLinter provides an interface to Verilator. Verilator is a open source HDL simulator and can be used as a linter with –lint-only option. For more information, you can see here, https://www.veripool.org/wiki/verilator Verilator is fast and easy to use to link with Sublime Text Editor on variable OS before runnning commercial simulaton and synthesis tools.

Prerequisite

  • SublimeLinter 3 installation - Guide from here. Currently, only support 3 not 4. Download from here
  • Verilator installation - Guide from here
  • Modified version of Verilator - Get from https://github.com/poucotm/verilator
  • Verilator PATH settings - SublimeLinter-contrib-verilator uses verilator_bin or verilator_bin.exe instead of verilator. You have to add PATH environment variable for verilator_bin or verilator_bin.exe

Verilator Original vs. Modified Version

Verilator originally simulates all entities having all include and module files. If you miss even a file, it will generate an error message and stop simulation or linting. It is not good to be used with a editor. People don't open all files to edit or it is tired to pass the file list to Verilator every time. In order to lint single file based, the original codes are modified. It can ignore include and externally defined module's instance and its port connection even if there's a real error in port connection. You can select one of them. If you want to use original version, you may have to put all files in the same directory. Because, Verilator basically searches missed files in the same directory.

Options for Modified Version

  • -Wno-IGNINC : Ignores include files
  • -Wno-IGNDEF : Ignores define which may have been defined outside
  • -Wno-IGNMOD : Ignores module instances
  • -Wno-IGNUNUSED : Ignore unused singnal warning connected to externally defined module instance

Troubleshooting

Turn on SublimeLinter's Debug Mode and Open the console of Sublime Text. You can check the communication status from SublimeLinter to Verilator. You can also add your own ignore_match messages by using them.

SublimeLinter: verilator: shift_reg.v ['D:\\Program\\verilator-3.902\\verilator_bin.exe', '--lint-only', ...
SublimeLinter: verilator output:
%Warning-LITENDIAN: c:/users/shift_reg.v:14: Little bit endian vector: MSB < LSB of bit range: 0:7
%Warning-LITENDIAN: Use "/* verilator lint_off LITENDIAN */" and lint_on around source to disable this message.
%Error: Exiting due to 1 warning(s)
