RAS needs to be reset or preloaded. For now I just reset it.
...
Fixed bug with the instruction class.
Most tests now pass. Only Wally-JAL and the compressed instruction tests fail. Currently the bpred does not support compressed. This will be in the next version.

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.

Hacked the sram memory models to reset their internal registers. This allows the simulation to run but is only temporary.
...
About 149307ns of simulation run.

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.

We now have a solid rough draft of the 2 bit sat counter branch predictor with BTB and RAS.
...
This is not yet tested but the system verilog does compile.

added branch predictor 2 bit table + SRAM model. The SRAM model is only approximate, but it does correctly model the read and write pipelined behavior.

Busybear: start checking CSRs
...
scounteren and mcounteren are currenly manually deleted from the CSRs list
(see slack channl #linux-bringup)
and 3 of the CSRs referenced are skipped because of weird locations for them
oh and this doesn't check their initial state, just their changing. This could be a problem
