RFSignal Integrity Tools: Vendors and Analysis
Advertisement
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.

A typical workflow includes schematic/layout editing, stackup definition, and output analysis (time waveforms, eye diagrams, and thermal analysis).
