Deno 2.4 Brings Back deno bundle, Improves Dependency Management and Observability
Deno 2.4 brings back bundling, improves dependency updates and telemetry, and makes the runtime more practical for real-world JavaScript projects.
A Python library that reads LEF and DEF files, extracts the RC parasitics and generates their corresponding SPEF file.
python3 -m pip install spef-extractor
spef_extractor <lef_file_path> <def_file_path> <wire_model which can be L or Pi> <edge_capacitance_factor which is a value between 0 and 1 where the default is 1>
```
For example:
```
python3 main.py osu035.lef rle_rec.def L 1
where osu035.lef
is the provided lef file and rle_rec.def
is its corresponding def file. Aftwards, we extract the RC parasitics and output them in a SPEF file named rle_rec.spef
(holds the same name as the def file by default).
In order to parse the lef and def files, we used trimcao's def and lef parser.
During our development, we had to make some assumptions to for the sake of simplicity:
