Is there an existing CVA6 bug for this?

  • I have searched the existing bug issues

Bug Description

The PR #2607 contains a scoreboard for the frontend stage.
Using this PR and the Dhrystone test, we detected that the RAS submodule doesn't pop an address from the stack when a return instruction is triggered.
In the event of the bug occurring, the RAS stack is full, and the variable in the Frontend module connected to the RAS input pop_data is equal to 1.
