Updated Dcache to fully support flush. This appears to work.
...
Updated PCNextF so it points to the correct PC after icache invalidate.
Build root crashes with PCW mismatch and invalid register writes.

Works until pma checker breaks the simulation by reading HADDR rather than data physical address.

Converted branch predictor preloads to use system verilog rather than modelsim's load command.

Fixed the issue with the batch mode not working after adding the function radix.

Added debug option to disable the function radix if not needed.

Function radix slows the simulation by 70 to 76 s (8.5%) for the rv64i tests.

Finally I think I have the function radix mapping across all applications correctly. I still need to clean up the code a bit so it is easier to understand.

Oups. I forgot to update other do files with the commands to preload the branch predictor memories.

Added FlushF to hazard unit.
...
Fixed some typos with the names of signals in the branch predictor. They were causing signals to be not set. Note there is a modelsim flag which prevents it from compiling if a logic is undefined.
I will look this up and add it to the compiler.

Wrote a bash script to generate custom modelsim radix which maps instruction addresses into human readable lables.
...
Once combined with some simulation verilog this will display the current function in modelsim.
