Hi
I try to develop a DUT model and some custom VVCs, I start to develop all things with modelsim 10.6d, next I move to questasim 2022.4. When I run test under modelsim, model works well but all go wrong in questasim. In addition I can’t find transaction_info related entries in the object window when I select a VVC in the instance tree.
There are know issues with this simulator?
I think Questa might be optimizing some signals away, have you tried running the simulation without optimizations? e.g. -voptargs=+acc
Hi
Nice catch! now transaction infos appear but I still collect wrong behaviour of simualtions. It needs more investigation: tests work fine under modelsim 
That’s strange, it’s difficult to say without looking at the testbench. Have you tested with some open source simulators?
