Memepu

TODO fill out.

Verymeme

Example commands:

memecad

memelang

memelang ./src/memepile/{integral,memory,pointer,stdintf,vector,string,token,main}.meme

Running tests

Run run.py to run the tests for both SCHEMATIC and non-SCHEMATIC verilog configurations.

Adding new symbols

Process for adding a new leaf module for verymeme:

Decide which Kicad symbol to use. If it's a new symbol, add data to pcb/kicadtools/ and generate using that.
Write a verilog module corresponding to that symbol
Write a mapping in memecad_map.json for the verilog module and kicad symbol.
Add it as a verilator module in verymeme/verilog/CMakeLists.txt
Add it to the SymbiYosys file in verymeme/verilog/formally_verify.sby

Fuzzing

Build with:

export PFX=./

cmake -DUSE_AFL=yes -DCMAKE_BUILD_TYPE=Release $PFX/verymeme AFL_SKIP_CPUFREQ=yes AFL_PRELOAD=/usr/local/lib/afl/libdislocator.so
afl-fuzz -m 1024M -i $PFX/verymeme/test_data/memelang/parsing -o memelang_fuzz
-x $PFX/verymeme/assets/afl/memelang.dict -- ./memelang @@

Or for persistent mode: cmake -DUSE_AFL=clang -DCMAKE_BUILD_TYPE=Release $PFX/verymeme

AFL_SKIP_CPUFREQ=yes AFL_PRELOAD=/usr/local/lib/afl/libdislocator.so
afl-fuzz -m 1024M -i $PFX/verymeme/test_data/memelang/parsing -o memelang_fuzz
-x $PFX/verymeme/assets/afl/memelang.dict -t 100 -- ./memelang
