GDSImportWizard

Latest version: https://github.com/YongshengGuo/GDSImportWizard/releases/latest

功能简介： 该工具可快速将GDS格式文件导入到Ansys HFSS 3D Layout中进行仿真建模和分析，支持非加密的IRCX文件、itf文件，也支持自定义的工艺文件格式（未直接支持的文件可通过CSV导入定义）。支持应用包括2.5D/3D Package、RF Chip、TSV、Silicon-SI等。

Readme: This toolkit enables fast import of GDS format files into Ansys HFSS 3D Layout for simulation modeling and analysis. It supports non-encrypted IRCX files, itf files, and custom process file formats (unsupported files can be imported through CSV definitions). Applications supported include advanced 2.5D/3D packaging, RF chips, TSV, Silicon-SI, and more.

A smart tool to translate GDSII to HFSS 3DLayout quickly:

  • Extract nets from GDS and import to EDB
  • Extract accurate material property from IRCX
  • Extract accurate layer thickness and stackup from IRCX
  • Automatic generate control xml for AEDT GDSII Importing
  • Support four type dielectric merge when importing (Update in V4.0)
  • Automatic create Via Group and SnapViaGroups
  • Automatic generate components on top and bottom layer for easier port setup
  • Synchronous import to AEDT when EDB prepared
  • Automatic detect and fix of small gaps between layers to avoid mesh Issue (New in V4.0)
  • Support sheet layers to simplify thinner metal layer mesh e.g. 0.001um（ New in V4.0 ）
  • support to generate temperature dependent material （ New in V5.0）
  • Add CSV input template to provide more flexible input for other Technology File（ New in V5.0）
  • Support New TSV Layer feature in 3D Layout 2022R1 (New in V5.0)
  • Support ConvertPolygonToCircle Feature to reduce mesh(New in V5.0)
  • More flexible setting options and enhanced command line(No-GUI) support(windows and Linux)
