Time domain vs frequency domain uses?

Hi Yuva09,

Broadly speaking, there are various sigrity point tools that are intended for Time domain and Frequency domain analysis. In each tool, there are different workflow items that are designed for specific applications.

Here are the Sigrity tools that perform simulations in both time-domain and frequency domain.

Frequency Domain:

PowerSI – It uses frequency domain effectively in analysis of package and board performance due to its electromagnetic field computation engine.

OptimizePI – It does a complete AC frequency analysis of boards and IC packages.

Clarity 3D Layout – This tool is designed for S-parameter model extractions for SI and PI analysis for laminated design structures, such as IC package and PCB designs.

Time-Domain:

SPEED2000/SPEEDEM – It is a layout based Finite-difference time-domain (FDTD) simulation tool, specializes in time domain analysis.

Topology Workbench – It is a general purpose topology exploration environment for what-if analysis of signal, power, or both signal and power together. The Topology Workbench performs automated die-to-die SI analysis in two configurations: Source-synchronous for parallel bus and serial links, with an emphasis on SerDes channels.

The SystemSI technology in this tool uses frequency domain, time domain and statistical analysis methods.
