Liberty file format parser for Rust

Example usage

Parse libraries from a Liberty file

use liberty_parser::parse_lib;

let lib_str = r#"
library(sample) {
    cell(AND2) {
        area: 1;
    }
}
"#;

for lib in parse_lib(lib_str).unwrap() {
    println!("Library '{}' has {} cells", lib.name, lib.iter_cells().count());
    let area = lib
        .get_cell("AND2")
        .and_then(|c| c.simple_attribute("area"))
        .map_or(-1.0, |v| v.float());
    println!("Cell AND2 has area: {}", area);
}

Limitations

• Doesn't automatically parse files from include statements

• Doesn't parse bus syntax in pin names. For example:

      pin (X[0:3]){
      }
