COSIM: Virtual Mode ISA Tests now failing after Chipyard bump to v1.7.0 #6

Open bchetwynd opened 1 year ago

bchetwynd commented 1 year ago

Seems like they have been failing for a while... as there seems to be a failure with CEP v4.0 as well (prior to chipyard bump)

So, for some reason they fail on Ubuntu w/Questasim, but not RHEL7 w/XCellium. Further investigation required.

They currently work on XCellium, but not Questasim. (v4.5_development_bchetwynd branch)

Virtual mode tests need to be revisited based on reviewing legacy code when it was passing.
