@GregAC - Think that @ctopal and @hcallahan-lowrisc will need some guidance on the efforts required for this + #1686

[GregAC]

This test is seeing some passes, failures are generally intricate co-sim mismatch bugs (but not RTL bugs) which take significant time to resolve so moving this to V3

[GregAC]

Closing as this will be picked up with general regression fixing required for V3
