Reply To: OSVVM: Build part of design and run only single test

[Jim Lewis]

Hi Hassan,
What version of OSVVM are you using? The current version is 2025.06a.
What simulator and version are you using?

Perhaps you can share the log files with me so I can look at it. Ultimately I need a reproducer test case of this.
Also try puts $::errorInfo

Did you do the exact sequence as above or were there other builds before it?

You need to run the test case with build. So put the RunTest in a *.pro file.

Ultimately you need to know a test case is going to fail – this may mean running it twice. Once observing that it failed and a second time rerunning it with a method to change the settings.

You can change the settings by:
1) Add a generic to TestCtrl that turns on info and debug messages.
2) Read the log enables from a file using ReadLogEnables. May not allow test wide settings.

I am looking for what is next and am open to suggestions. One thing I need to do is to make sure ReadLogEnables allows test wide settings – either independent of or matching the test case name. Another might be a mechanism to turn on mirroring.
