# OTBN memutil wrapper | |
This code is a wrapper around `VerilatorMemUtil` (defined in | |
`hw/dv/verilator/cpp`). | |
To use it, depend on the core file. If you're using dvsim, you'll also | |
need to include `otbn_memutil_sim_opts.hjson` in your simulator | |
configuration and add `"{tool}_otbn_memutil_build_opts"` to the | |
`en_build_modes` variable. |
