Extended and external tests for Verilator testing

Purpose

This project contains additional tests for Verilator. These are generally tests that run for a long time, and/or use source code from other projects.

To file issues, etc, please see https://verilator.org.

Usage

Initial prep

git submodule update

Run an individual test:

export VERILATOR_ROOT=location  # if your shell is bash
setenv VERILATOR_ROOT location  # if your shell is csh
t/t_a_hello.pl

Automatically run these tests as part of normal Verilator "make test"

export VERILATOR_TESTS_SITE=$VERILATOR_TESTS_SITE:$PWD  # if your shell is bash
setenv VERILATOR_TESTS_SITE $VERILATOR_TESTS_SITE:$PWD  # if your shell is csh

Cleanup

make clean

Adding additional tests

To add additional tests, add a t/t_{name}.pl file. See the Verilator internals documentation for instructions on the test file format.

To be accepted in this package, an external submodule tested here must:

• Be under an open source license.
• Be available as a git repository.
• Be self checking (potentially checked by the t/ script you write).
• Be Verilator lint clean (using lint_off pragmas in code is fine).
• Be willing to consider patches as needed (i.e. not a "dead project").
• Already run CI against a fixed version of Verilator
