850d8c2b24 Fixed slight bug in config from parameterization. 2023-07-07 16:33:34 -05:00
Ross Thompson
4b3b590f21 Fpga does not correctly boot linux. I think the solution here is to revert out all substantive changes except for parameterization and then add them back in one at a time. This is necessary because the parameterization is not completed in one contiguous group of commits. 2023-06-22 12:55:49 -05:00

e3cf1419ed Deleted remaining old configs except fpga as I still need to create the parameterized version. 2023-06-15 14:08:13 -05:00

44c72c20e2 Actually removed old `define configuration file for rv64gc. There were a lot of dangling problems. 2023-06-15 14:05:44 -05:00

9bae203d1c 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

80cdb02d43 Changes required to make verilator compile wally's testbench to c++. Not actually tested in simulation yet. 2023-05-31 16:51:00 -05:00
Ross Thompson
e56497101a Updated source code to be compatible with verilator 5.011 for lint only. 2023-05-31 10:44:23 -05:00

340aac0934 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
Ross Thompson
7c364d5a77 Updated mmu's tlb and hptw to use Lim's parameterization. 2023-05-24 18:02:22 -05:00
Ross Thompson
d3123fc00a Updated a large number of the source files to use parameters rather than `defines. Based on Lim's work. So far there is no simulation slow down. 2023-05-24 14:05:44 -05:00

c5aeb08e5c Trying to figure out why the parameterization slowed down modelsim so much. 2023-05-24 12:44:42 -05:00

63473a1477 Changed DIVN comparison from NF to NF+2. Shouldn't make a difference on our word sizes of XLEN=32/64, NF = 10/23/52) but is more proper in the general case. 2023-05-15 03:51:59 -07:00
