vcd2vpd not found #38

Closed ninode closed 7 years ago

ninode commented 7 years ago

Hello,

I'm running the make run-vpd in the emulator. I get the following: make run-vpd

rm -rf output/rv64ui-p-add.vpd.vcd && mkfifo output/rv64ui-p-add.vpd.vcd
vcd2vpd output/rv64ui-p-add.vpd.vcd output/rv64ui-p-add.vpd > /dev/null &
./emulator-DefaultCPPConfig-debug +dramsim +max-cycles=100000000 +verbose -voutput/rv64ui-p-add.vpd.vcd +loadmem=output/rv64ui-p-add.hex none 3>&1 1>&2 2>&3 | /home/alpha/lowrisc-chip/riscv/bin/spike-dasm  > output/rv64ui-p-add.out && [ $PIPESTATUS -eq 0 ]
/bin/bash: vcd2vpd: command not found

Could you please help me fix it ? Is it necessary to simulate RISCV on Zynq ? Or is there another way ?

Thank you

You are using an old release of lowRISC as this vpd make target has been removed when we replaced VCS with Verilator as the default simulator.

This vcd2vpd command is a utility command provided by Sysnopsys VCS simulator, which is a commercial tool. It should not be necessary as long as the vcd file is generated. You can use gtkWave (a free tool available on most Linux platforms) to see vcd files.

Instead of using the vpd make target, use the vcd make target instead (if I recall it right, we did provide this choice).

Thank you. Are you referring to untetherv2.0 or LowRISC with trace debugger ?

wsong83 commented 7 years ago

Yes, untether-v0.2 and debug-v0.3 has replaced VCS with verilator. There is no C++ emulator in these two. In the tagged-memory-v0.1 version, make target run-vcd should give you vcd files in emulator.
