Tools and vendors
The tools fall into the following broad categories.
Field solvers provide physically accurate solutions. They calculate electromagnetic parameters by directly solving Maxwell's equations. Due to high calculation burden they are applicable only very small designs or to parts of the designs.
Approximate solutions with pattern matching techniques are the only feasible approach to extract parasitics for complete modern integrated circuit designs.
ANSYS Q3D Extractor
ANSYS Q3D Extractor uses method of moments (integral equations) and FEMs to compute capacitive, conductance, inductance and resistance matrices. It uses the fast multipole method (FMM) to accelerate the solution of the integral equations. Outputs from the solver include current and voltage distributions, CG and RL matrices.
FastCap and FastHenry, from MIT (Massachusetts Institute of Technology) are two free parasitics extractor tools for capacitance, and inductance and resistance. Quoted in many scientific articles, they are considered golden references in their field. Windows versions with viewer and editor are freely available from FastFieldSolvers.
StarRC from Synopsys (previously from Avanti) is a universal parasitics extractor tool applicable for a full range of electronic designs.
QRC from Cadence is a parasitic extractor tool for both digital and analog designs and parasitics extraction check have to be carried out to prepare the design for postlayout verification.
QuickCap NX from Synopsys is a parasitic extractor tool for both digital and analog designs. It was based on QuickCap developed by Ralph Iverson of Random Logic Corporation, which was acquired by Magma and Synopsys.
Calibre xACT3D from Mentor Graphics is a parasitic extractor tool for both digital and analog designs. It was based on PexRC developed by Wangqi Qiu and Weiping Shi of Pextra Corporation, which was acquired by Mentor.
CapExt from CapExt AS is a parasitic extractor tool for extracting capacitance from PCBs based on Gerber files.
