stupidf 0.2.0

Parsing of STDF file format to DataFrame with Python bindings

stupidf

stupidf is a library for limited parsing of STDF files. The STDF structure can be used directly in rust, or alternatively sent out to Python using the parse_stdf function.

STDF is the Standard Test Data Format and is commonly used for high-volume test of semiconductors in Automated Test Equipment (ATE) systems.

The purpose of the library is to quickly and efficiently parse STDF files (which are a fairly unfriendly binary linked list-based format) into more friendly polars DataFrame format.

Not all record types are implemented because they're not relevant for my purposes. Implementing new records is straight-forward, following the others.

Example

In rust

use stupidf::data::STDF;
use polars::prelude::*;

let verbose = false;
if let Ok(stdf) = STDF::from_fname(&fname, verbose) {
    let df: DataFrame = (&stdf.test_data).into();
    let df_fmti: DataFrame = (&stdf.test_data.test_information).into();
    println!("{df:#?}");
    println!("{df_fmti}");
    }

Also contains Python bindings to this functionality, e.g.

   import stupidf as sf
   stdf = sf.parse_stdf("my_stdf.stdf")
   stdf['df']

Installation

To install the rust CLI binary:

cargo install stupidf

To add the stupidf library to a rust project, add to the Cargol.toml:

[dependencies]
<... snip ...>
stupidf = "0.1.0"

To install the Python bindings and pre-built wheel (linux only currently):

pip install stupidf

Building from source

The rust library can be compiled simply with

cargo build --develop

Docs can be built and viewed with

cargo docs
cargo docs --open

The Python bindings can be made using maturin. Activate the desired virtualenv, then install maturin and use it to build the bindings

pip install maturin
maturin develop
