Invarian’s goal is to provide the industry’s best solutions for full-chip sign-off analysis for complex, high-performance integrated circuits (ICs). . Today’s chips are too large and complex for existing tools. Achieving accurate results demands a new paradigm. Success requires attacking the problem from multiple angles. Invarian solutions deal with design complexity in a variety of ways. By shifting the methodology to true time domain we solve the problem of scale. Along with the ability to handle large chips comes shorter simulation runtimes without the sacrifice of accuracy. Invarian tools use algorithms designed for today’s parallel computing systems. We are able to leverage the entire compute environment. Our concurrent analysis delivers efficiency and accuracy that existing tools lack. An easy to use backend flow eliminates cumbersome design modifications. The incredibly smaller process geometries in the advanced silicon process technologies are today so expensive that there can be no risk of design failures and often too much guard-band is added which hinders the competitive edge of truly taking advantage of the processes enablement. Whether designs are massive in size with billions of transistors on a single chip or having complex physical features including true 3D stacking that traditional sign-off analysis tools simply cannot handle. By using Invarian’s solutions, designers have the ability to design with accuracy and have the confidence the taped-out design will yield as expected.

Invarian’s Power Platform delivers all the sign-off analysis solutions needed from IR-drop analysis to thermal analysis and power analysis in a concurrent environment that enables fixes as your go, this ability gives designers the confidence to get the most power and performance capabilities with the fastest sign-off time.

Invarian was formed in 2008 and is headquartered in Sunnyvale, California. We have top tier-one customers validating that our technology correlates with physical measurements in silicon in 40nm, 28nm and designs in 20nm and below including true 3D analysis.
