Was able to alias the buried signal and then use force in to drive it from the testcase giving me more control over the specific time that the signal changed during testing.

Thanks Jim.

If the signals you want to drive are on an interface, then your verification component can be built so that it triggers all error conditions.

If the signals you want to drive are deep in your design, you can test that capability at the level where those signals are exposed.

Alternately if signals you want are deep in the design and you…[Read more]
