Ansoft released Q3D Extractor version 7 on August 23, 2005. The 3D quasi-static electromagnetic tool extracts parasitic circuit parameters from interconnect structures and generates equivalent SPICE circuits. The release added broader CAD and layout import support and a meshing algorithm designed to handle anomalies in imported geometry.
What is Ansoft Q3D Extractor version 7?
Q3D Extractor is a quasi-static electromagnetic parasitic-extraction tool. It analyzes interconnect structures to calculate electrical parameters that can be represented in a circuit model, then automatically generates an equivalent SPICE circuit. EDN reported the version 7 release on August 23, 2005. EDN

What did Q3D Extractor v7 add?
More import options
Version 7 improved importing 3D CAD models and layouts for integrated circuits, printed circuit boards, and packages from third-party tools. This was intended to make it easier to bring design geometry into the extraction workflow.
Meshing designed to tolerate geometric anomalies
Ansoft added a fault-tolerant meshing algorithm to cope with anomalies in geometric data originating in CAD and EDA software. The announcement described the intent as making meshing tolerant of those anomalies; it did not report a success rate or benchmark.

Can Q3D Extractor extract RLC or RLCG parasitics?
Yes. The release report says Q3D Extractor computes 3D RLC and 2D RLCG parameters from interconnect structures, then automatically generates an equivalent SPICE circuit. The two parameter types are tied to different extraction dimensions in the report: 3D RLC and 2D RLCG.
Which operating systems did Q3D Extractor v7 support?
The 2005 release report listed the following platforms:
- Microsoft Windows 2000
- Microsoft Windows XP
- Microsoft Windows Server 2003
- Microsoft Windows XP Professional x64
- Solaris
- HP-UX
- Red Hat Linux
These are the platforms documented for version 7 at release, not an indication of compatibility with current operating systems.
