Mirrored value in frontdoor and backdoor

UVM

Hello Guys ,

When I call the Write method using BACKDOOR access, the desired value and the mirrored value are the same.

However, with FRONTDOOR access, when I call Write, the desired value differs from the mirrored value.
even after calling ‘Read’ , the mirrored value is differs from the desired value

Could you please explain why this happens? Should I add a predictor to resolve this issue?

Thanks!

You need an explicit predictor(recommended) or implicit prediction.
