Hi, Emulator is not generating the vcd waveforms.: ./emulator-freechips.rocketchip.system-DefaultConfig-debug -v rv64ui-p-add.vcd $RISCV/riscv64-unknown-elf/share/riscv-tests/isa/rv64ui-p-add This emulator compiled with JTAG Remote Bitbang client. To enable, use +jtag_rbb_enable=1. Listening on port 46749 FAILED (code = 1701544776, seed 1518438930) after 63868 cycles

Hmm, Probably issue with Jtag. when I removed it from emulator.cc then no warning generate. Can i get any documentations or detail about purpose of JTAG and how it works ? thanks !
