It takes about 430 seconds for the full test,

Aldec donated an educational license of Riviera-Pro, which isn’t representative of the speed you’d get from the real product.

This is the reason it takes such a long time:

# KERNEL: Warning: You are using the Riviera-PRO EDU Edition. The performance of simulation is reduced.
# KERNEL: Warning: Contact Aldec for available upgrade options - [e-mail].

It takes about 430 seconds for the full test, which is much slower than all of the other simulators I tested, and this test alone takes up about half of the regression run time in CI.
