GDBWave

GDB server to debug CPU simulation waveform traces.

See GDBWave - A Post-Simulation Waveform-Based RISC-V GDB Debugging Server.

Usage

Start gdbwave

cd ./src
make run

This does the following:

• Read in an FST file.
• Extract all the instruction addresses with associated simulation timestamp.
• Extract all CPU writes to the CPU register file
• Extract all CPU writes to external memory
• Start a GDB server
• Makes GDB believe that it's dealing with an active or simulated CPU
