If cloned into rocket-chip directory use
./install-symlinks
You can then test it using the emulator
cd ../emulator && make CONFIG=Sha3CPPConfig run-asm-tests
You can emulate the software implementation of sha3 by running
./emulator-Top-Sha3CPPConfig pk ../sha3/tests/sha3-sw.rv +dramsim
or
./emulator-Top-Sha3CPPConfig pk ../sha3/tests/sha3-sw-bm.rv +dramsim
You can emulate the accelerated sha3 by running
./emulator-Top-Sha3CPPConfig pk ../sha3/tests/sha3-rocc-bm.rv +dramsim
or
./emulator-Top-Sha3CPPConfig pk ../sha3/tests/sha3-rocc.rv +dramsim
The -bm versions of the code omit the print statements and will complete faster.
