testbench_wb.v: unify verbose output with axi testbench
 2017-04-07 10:05:13 +02:00
Antony Pavlov 7c852571f0 testbench_wb.v: unify verbose output with axi testbench 
Unification of testbench output makes it possible to use the diff
utility for comparing testbench instruction traces.

Alas the testbench and testbench_wb traces are differ
because of interrupts, e.g.

    picorv32$ make testbench_wb.vvp
    iverilog -o testbench_wb.vvp -DCOMPRESSED_ISA -DRISCV_FORMAL testbench_wb.v picorv32.v
    chmod -x testbench_wb.vvp
    picorv32$ make testbench.vvp
    iverilog -o testbench.vvp -DCOMPRESSED_ISA -DRISCV_FORMAL testbench.v picorv32.v
    chmod -x testbench.vvp
    picorv32$ vvp -N testbench_wb.vvp +verbose | head -n 856 > /tmp/testbench_wb.log
    picorv32$ vvp -N testbench.vvp +verbose | head -n 856 > /tmp/testbench.log
    picorv32$ diff -u /tmp/testbench.log /tmp/testbench_wb.log

Antony Pavlov 0967a39c1d testbench_wb.v: fix output stuff 
This patch fixes wishbone testbench output issue:
'DNNE' instead of 'DONE', i.e.

    Cycle counter ......... 546536
    Instruction counter .... 69770
    CPI: 7.83
    DNNE

    ------------------------------------------------------------
    EBREAK instruction at 0x000006C4
