36dfff5ee8 Adjust Verilog testbench to use new debug_stats_pcr signal that has been exported to the top level. It is the or-reduction of the stats pcr for each core. Push rocket (export stats pcr to top level). This scheme is cleaner than digging into the hierarchy. 2013-09-25 01:21:41 -07:00

3532ae0b79 From Andrew, actually mark scoreboard when rocc instruction with a writeback is issued. Also, fix an issue with AccumulatorExample not properly tagging its memory requests. Finally, reverted changes from f27429c to more properly follow the spike model (always return previous value of accumulator). 2013-09-24 10:54:09 -07:00
