# `ver2gal`: Yosys Netlist-to-JEDEC compiler
|
|
|
|
This program converts a Yosys JSON netlist that has been techmapped with the GAL techlib to a JEDEC fuse file to be flashed to hardware.
|
|
|
|
## Build and Install
|
|
|
|
You'll need a relatively recent version of Rust and `cargo`, the package manager. If the version included in your distribution is too old, install `rustup` to install
|
|
a recent stable release.
|
|
|
|
Build with `cargo build`. This will produce a `ver2gal` binary in `target/debug`. The program can be installed globally with `cargo install --path .`.
|
|
|
|
## Usage
|
|
|
|
The primary mode is the `synth` subcommand:
|
|
```
|
|
Usage: ver2gal synth [OPTIONS] <NETLIST> <CONSTRAINTS>
|
|
|
|
Arguments:
|
|
<NETLIST>
|
|
<CONSTRAINTS>
|
|
|
|
Options:
|
|
--chip <CHIP> [default: gal16v8] [possible values: gal16v8, gal22v10]
|
|
-h, --help Print help
|
|
```
|
|
|
|
When provided a netlist JSON file and a PCF constraints file it will produce a `.jed` fuse file called `output.jed`.
|
|
|
|
**Important Note**: This program should be run in the same directory as the `shrink_sop.tcl` script, as it will automatically call the script
|
|
if a SOP needs to be split. This should only be necessary in the `gal22v10` mode.
