H extension for VS privilege #100

Open kong-ling-hui opened 3 months ago

kong-ling-hui commented 3 months ago

I have added VS privilege in PrivilegeLevel.py and some H CSR initial program. Now I can pass compilation, but when I generate case, which just has a simple "ld/sd" instr, I encounter some errors. I want to know the reason of this errors. Can you give me some help? Here are error messages:

The reason of this error is that the destination of instruction "JAL" is not meeting FORCE expectation. I have skip this error-detected mechanism about this error and FORCE normally generate case, but this error is still not completely solved. Looking forward to your reply~

what the role of the AddressTable.CC and its Manager.CC
