fc7016eea6 Fixed the AMO dcache bug. The subword write needs to occur before the AMO logic.
Fixed logic for trace update in the M and W stages.  The M stage should not update if there
is an instruction fault.

9be10cdc8b Partial conversion of the linux trace checking to read in the file in the Memory Stage so it is possible to overwrite registers, memory, and interrupts. 2021-08-06 16:06:50 -05:00

3582be4dbb Fixed issue with desync of PCW and ExpectedPCW in linux test bench. The ERROR macro had a 10 ns delay which caused the trace to skip 1 instruction. 2021-08-05 16:49:03 -05:00

b9902b0560 Fixed how the dcache and page table walker stall cpu so that once a tlb miss occurs the CPU is always stalled until the walk is complete, the tlb updated, and the dcache fetched and hits. 2021-07-15 11:00:42 -05:00
