Tempus Timing Signoff Solution 


Massively parallelized timing analysis and physically aware multi-mode, multi-corner optimization for faster design closure and signoff

Cadence® Tempus™ Timing Signoff Solution is a complete standalone tool that delivers silicon-accurate timing signoff and signal integrity analysis that ensures operational chips after tapeout. By tightly coupling the design implementation environment with the timing signoff environment, the Tempus solution enhances timing convergence throughout the design flow and greatly reduces the time to design closure.

The Tempus Timing Signoff Solution provides full-chip static timing analysis (STA) with gate-level delay calculation, signoff-level timing and signal integrity (SI) analysis, statistical timing and leakage analysis, advanced on-chip variation analysis, and the advanced node functionality required for double-patterning and waveform effects.

The solution removes the iteration bottleneck by providing a consistent, integrated Common Timing Engine for both the design implementation stage and the final timing verification stage of the design cycle. As a result, you get correlation and convergence between implementation and signoff for faster timing closure.
