ba3aed8760 Finally fixed bug with the set associative design. The issue was not in the LRU but instead in the way selection mux.
Also forgot to include cacheLRU.sv file.

c9775de3b2 testbench hack to ignore MTVAL for illegal instr faults; testbench upgrade to not check PCW for illegal instr faults; testbench hack to not check speculative instrs following an MRET (it seems MRET has 1 stage more latency than a branch instr) 2021-07-20 05:40:39 -04:00

2ee97efb9c Fixed a complex bug in the dcache, where back to back loads would lose data on the load before a stall occurred. The solution was to modify the logic for SelAdrM in the dcache so that a stall would cause the SRAM to reread the address in the Memory stage rather than Execution stage. This also required updating the ReadDataWEn control so it is always enabled on ~StallW. 2021-07-19 12:32:16 -05:00
