# README

Small assembler that generates Logisim readable memory files for [this](https://gitlab.com/ChUrl/logisim-cpu).
**Since I stopped using Logisim for the CPU design, this repository is succeeded by [this](https://gitlab.com/ChUrl/systemverilog-rom-assembler).**

## Usage

`lasm -i <inputfile> -o <outputfile>`
