Customer References

MunEDA circuit migration tools are successfully proven in numerous industrial circuit design projects with global semiconductor companies since many years.

Infineon – SRAM Bitcell Analysis of 6T SRAM Bitcell in 65nm with MunEDA WiCkeD High Sigma Worst Case Analysis – verified 2 sigma global and 6 sigma local WCD

After migration to the latest FinFET process node we used MunEDA’s high sigma analysis features to identify in our high performance SRAM memory cells both mismatch and scaled VDD degradation of the read/write stability. Following we have taken advantage of WiCkeD‘s powerful deterministic optimization tools to improve the write signal under consideration of the best area trade-off.

SKHynix – MunEDA’s tools are best-in class for interactive and fully automatic yield analysis and optimization in circuit design. As for every semiconductor company, design targets like high performance and yield are number one research goals that imply both profitability and time to market. We added MunEDA’s solutions to Hynix design environment to follow our track in establishing best design methodologies to our design groups and therefore improve quality assurance to our customers.
