This page lists Signal Integrity Tools vendors and developers, covering features and license costs of tools from reputable sources.

Why Signal Integrity Tools?

Signal integrity analysis is crucial for high-speed board designs and VLSI circuit designs. It helps identify potential signal impairment issues within the PCB layout before manufacturing. Common issues addressed include:

Impedance mismatches at interconnects
Signal losses through traces
Inconsistencies in differential line spacing or width
Signal or return path problems
Crosstalk
EMI (Electromagnetic Interference)

Signal integrity tools are valuable throughout the design process, from pre-layout to post-layout stages, ensuring the final board meets desired specifications.
