The Challenge Accurate transistor-level analysis of crosstalk-delay As designs go down to 90-nm and below, crosstalk-delay becomes more than 25% of total delay. Prior solutions including traditional static timing analysis with optional 3rd party crosstalk delay analysis do not provide the accuracy and productivity that is required. Concurrent timing and SI is a must to achieve silicon success. Full chip timing verification Transistor- and gate-level static timing analysis need to work together to achieve full chip timing verification (i.e) a seamless and accurate timing analysis flow from custom design to gate-level with PrimeTime is required. To achieve higher productivity, NanoTime has the same commands as PrimeTime whenever they are applicable. Concurrent timing and signal- integrity (SI) analysis provides higher predictability and better productivity over existing solutions. NanoTime offers integrated timing and crosstalk- delay analysis to achieve higher silicon accuracy. With its unmatched ability to recognize complex custom design structures, embedded NanoSim technology for dynamic circuit evaluation and the state-of-the-art RC reduction algorithm, NanoTime delivers accuracy within 5% of HSPICE Ease of use features improves productivity. The ease-of-use features include easy setup with Tcl, the Synopsys common command interpreter; interactive timing analysis that allows multiple analyses in a single session and a seamless flow with PrimeTime that supports Synopsys Design Constraints (SDC). New algorithms that result in a five- fold increase in performance over existing solution without sacrificing accuracy
