Lars-Peter Clausen	2d611c4347	ivtest: pr1002: Avoid race condition ... The pr1002 test has a always block with the `dataout` in its sensitivity list. It compares `dataout` to `expected_dataout`. Both `dataout` and `expected_dataout` depend on `datain` and are updated in the same cycle. This means there is no guarantee in which order they are updated and the always block might get scheduled before `expected_dataout` has been updated. This can lead to a test failure. To avoid this slightly change the test to use a task to perform the comparison and add an explicit delay before the task is executed so that all updates have a chance to be fully resolved Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>	2024-01-20 10:32:55 -08:00
Stephen Williams	cea237b407	Add ivtest to the iverilog source tree ... By adding ivtest to the iverilog source tree, it is easier to keep the regression test synchronized with the source that is being tested. This should be especially helpful for PRs that add a new feature, and have a matching ivtest PR with the regression test for that feature.	2022-01-15 10:18:50 -08:00
