43f6b7cfa3 fixed bug in testvector extract script 
- old script skips first 2 lines in rv32m case, new script only skips first line

9b3a876656 fixed bug in rv32M test vector generation code 
- prior code skipped every other line in the reference file, so it only generated half the test vectors, with half of them having the wrong answer
- prior code also opened test vector file to be written to in "append" mode, and I changed to write mode (so that the script overwrites instead of adding to an existing file)

b8474b208e Uncore is now parameterized. 2023-05-26 16:24:12 -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

923c00b928 I think I've solved the slow down issue. Parameters can't be mixed with cvw_t and other types. 2023-05-26 13:56:51 -05:00

3765ebfb9f PMA checker's address decoder is now parameterized. I did not see bit slicing in Lim's code. I'm not sure how they got around this issue. 2023-05-26 11:06:48 -05:00

Ross Thompson
7fc53226ac MDU and hazard unit now also parameterized. Based on Lim's work. Again I want to clarify this their work. Not mine. I'm just doing this because the merge had an issue. 2023-05-24 15:01:35 -05:00

8f9151b125 More parameterization. Based on Lim's work. EBU, IFU (except bpred), and IEU done. 2023-05-24 14:56:02 -05:00

e33db7f9a7 More parameterization. Copied Lim. Still no slow down. 2023-05-24 14:49:22 -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
