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
