Liberty parser & datastruct project recommendation

[zao111222333]

Hi,
I know this project from Rust China Conf 2024, that is a great open-source project and I am very interested in. Here I want to recommend my Liberty data structure & parser project which I have maintained for nearly 2 years. https://github.com/zao111222333/liberty-db

This project implements the Liberty syntax (simple/complex/group) and almost all Liberty data structures. Its parser can recognize weird syntax in foundry-provided library (e.g. TSMC), meanwhile the output formatted .lib file is compatible with library compiler.
The parser utilizes Rust’s procedural macros to enhance performance as much as possible through static methods. Additionally, the complete parser & formatter binary implemented with this library is only ~2MB in size.

Here is a benchmark result, the strength of liberty-db are not fully realized, since it also post-processes the data and stores it in specific data structures, in addition to parsing the syntax.

This project will greatly benefit from feedback and suggestions for improvement. Hope we can collaborate, thanks!

Hi Junzhou Thank you for your email and for expressing interest in our project. I also had the chance to review the liberty-db, and I must say, it’s an incredibly valuable initiative. We will continue to keep a close eye on the progress of the liberty-db project, and I look forward to the possibility of more collaboration between iEDA and liberty-db in the future. Best regards, Xingquan

Rightnow the liberty-db's APIs have got stable and will not change. I also add examples for easily getting start, we can have a try and see if that meets the usage scenario of iEDA :)

OK, Thanks for your feedback, we will try to use liberty-db Best regards, Xingquan —————————— Xingquan Li,
