a963e50e88 It's a bit hacky, but the plic now passes the regression test and should be compatible with the fpga. 2023-07-06 14:07:37 -05:00

786329b11d Fix items related to testing of TestFloat that were not always matching. The issue resulted due to the repeat statement that interferes with the always block. I separated the two to allow them to work correctly 2023-06-26 10:14:49 -05:00

7aecd72c35 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

fixed bug in combined intdivrem testvector extract script
 2023-06-22 12:38:45 -04:00

f6a3474550 fixed bug in testvector extract script 
-old script skips first 2 lines in rv32m case, new script only skips first line
- 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)

66643eb78e Update sim-testfloat to fix errors due to bad config element. I am not sure of the reasoning, but the specific path to the testvector was not getting inserted in Questa. This modification also adds features to test individualized tests (.e.g, binary16 only) -- documentation is added in the FPbuild.txt file 2023-06-20 17:26:54 -05:00
