Signal Integrity

Zettaone supports advanced analysis with extensive experience on highspeed interfaces. As clock speeds and data rates are increasing and industry need high-speed interfaces with multi-GHz frequencies, Signal integrity (SI) and power integrity (PI) analysis are key factor achieving a PCB or system level performances. Simulations are performed with leading-edge SI software to ensure the board performance meets as expected. Multiple tools are used to perform a wide range of analysis tasks including 3D EM full-wave extraction, network analysis, channel analysis, AC power analysis and DC power analysis.
