in tv80_core.v line 1242, original: Pre_XY_F_M<=#1 mcycle; should be Pre_XY_F_M <=#1 (mcycle0)? 1: (mcycle1)? 2: (mcycle2)? 3: (mcycle3)? 4: (mcycle4)? 5: (mcycle5)? 6:7;
comparing to T80 vhdl design, I found this is a mismatch
Change committed, will verify correctness tomorrow and close. Thanks for the report.
