Overview With process geometries reaching 90-nanometers (nm) and below, there are many nanometer effects that can impact timing. Accurate analysis of these effects is required to identify real timing issues. Synopsys’ NanoTime tool is the next-generation transistor-level static timing analysis solution that addresses the emerging challenges in signal integrity (SI) analysis associated with custom designs. NanoTime offers concurrent timing and SI analysis, accuracy within five percent of HSPICE®, and the performance required to analyze complex transistor circuits overnight. Its seamless integration with Synopsys’ PrimeTime® product enables full-chip analysis of designs that includes both gate- and transistor-level blocks. NanoTime is a key component of the Synopsys custom design verification solution that includes CustomSim® and HSPICE for circuit simulation and ESP-CV for symbolic simulation.
