调研方向

Start by extracting the uploaded Gerber samples and reproducing the import with default settings in KLayout v0.30.7 on Windows. Compare the two samples, including the .art file, and identify whether parsing causes the freeze and memory growth. Done means the files import without runaway memory use and the reported .art extension is supported or its limitation is clarified.

描述

Gerber file parsing failed, the software froze, and memory usage reached 100%.

klayout v0.30.7
windows 10 x64
The PC memory size is 48GB

All parameters are set to default values. Finally, click "Import".
The software may freeze, Windows memory usage may continuously increase, and Gerber files may fail to parse correctly.

3.I have uploaded the Gerber file; please unzip it.

4.Additionally, klayout does not support Gerber files with the *.art extension. I have also uploaded a sample file here.
