Ansys Q3D extractor is a quasi-static 3D solver for extracting lumped RLGC parameters and SPICE models. Ansys Q3D uses three different solvers to create mesh on the design and to get accurate results. All three solvers are different in terms of mesh creation, convergence settings and results. Q3D extractor calculates resistance, capacitance, inductance and RLGC parameters.
In this course, you will learn the basics of Ansys Q3D Signal Integrity and Quasi-static EM field simulation workflows. This course will cover concepts like setting up the workflow; assigning boundaries, nets and terminals; setting up the frequency parameters and sweep; and plotting the results with the field overlays. This course will also cover some basic equations related to capacitance and inductance and then introduce a few basic matrix operations. It introduces two important capacitance matrices — Maxwell and SPICE capacitance matrices. By the end of this course, you will be familiar with a few methods of capacitance and inductance matrix reduction, with related examples.
