XODUS32-5S

A 5 stage 32 bit RISC-V I(Base) extension core

Dependencies

  • sbt
  • openjdk 18

RTL Generation

  1. Edit the assembly.s file with your own assembly code and place the hex instructions in hex.txt in the assembly directory. A template file is also given. Follow the pattern for a successful simulation.

  2. Make sure you're in the root directory of the repository.

sbt
  1. The sbt server will be started. To generate the RTL file,
testOnly Top.TopTest -- -DwriteVcd=1
  1. A Top.vcd file is situated in test_run_dir/XODUS32_5S/. Use a vcd file viewer like gtkwave to view the RTL.

RVFI Log

A log file in the RVFI format can also be generated. Place a disassembly file, named test.s in the scripts directory. From the root directory, cd into the trace directory and execute traceGenerator.sh file.

cd trace
./traceGenerator.sh

A CSV file trace.csv along with a log file trace.log will be generated.
