Tips for Getting the Best PrimeTime Performance 

At today's advanced technology nodes of 65-nm and below, designs continue to grow in both complexity and size. Turnaround time becomes more difficult and more critical than ever, leading to increased demands on the performance and capacity of design tools.

The 2008.06 PrimeTime® Suite, which includes PrimeTime SI, PrimeTime PX, and PrimeTime VX, delivers 4X faster runtime and 2X less memory over the 2006.12 release to address these demands. With a proven performance and capacity on 50+ million-instance designs, the 2008.06 release sets a new performance standard for both static timing analysis and signal integrity analysis. As a result of the latest enhancements, designers benefit with dramatic productivity boosts in their timing sign-off and timing closure flows.

Tips for Getting the Best PrimeTime Performance
Karen Linser, staff applications engineer in Synopsys’ Implementation Group, describes a few easy ways for getting the best PrimeTime performance and achieving faster sign-off analysis.

Tips for Getting the Best PrimeTime Performance
  • Use binary parasitic files (SBPF format) instead of ASCII files (SPEF format)
  • Avoid Tcl inefficiencies such as generating the same large Tcl collection repeatedly
  • Use set_clock_groups instead of set_false_path to define clock domain relationships
