## Usage

Set parameters `A1_LEN` and `A2_LEN` to the argument size of the
first and second integer. Set `A2LEN_SIZ` equal to
`floor(log2(A2_LEN) + 1)`.

After inputting each integer, pulse `arm` and wait until `fin` goes
high to retreive the output in `outn`.

## Simulating

Simulation is done with Verilator. Run `make`.
