9471dcd296 Refactored the fpga and testbench so the RVVI can be synthesized cleanly and simulated without any major code changes.
Adds three new configuration parameters to control enabling the RVVI packetizer and how much latency should exist between packets and the initial startup delay.

28752303be Added ZCA/ZCF/ZCD/ZCB support. Doesn't break regression, but not tested. Need to get tests for Zcb. Draft tests are in riscv-arch-test but not yet committed there 2023-10-04 12:28:12 -07:00

95c653e7df Fixes the bpred-sim.py to support command line parameterization of the branch predictor while using the new parameterization. This is definitely a hack, but I don't see a better way. 2023-09-15 14:05:26 -05:00

b756b248b4 Wow. The newest version of Vivado does not like the enums as parameters.
The solution is simple.  I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

a8a8422557 Updated parameterization types. Modelsim version 2022.1 did requires defaults to a 32 bit integer. The base and ranges for the address decoder need to be larger. 2023-06-09 09:28:24 -05:00

1315a0bf4a Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check. 2023-05-26 16:00:14 -05:00
