CharFlo-Cell! is a next-generation characterization solution for standard cell and I/O library, being reliability and manufacturability aware. Using the patented multi-goals bisection method, CharFlo-Cell! analyses inside the cell and performs all kinds of signal integrity checks (e.g. signal noise, glitch, meta-stability, and delay etc) during the iterative process.
With high-throughputs and easy-setup, CharFlo-Cell! is a fully automatic system providing predictable results, and ensuring first silicon success. Together with Legend's circuit simulator MSIM, CharFlo-Cell! provides the best price-performance solution.
