PrimeTime With Multicore Support 

PrimeTime® static timing analysis (STA) suite includes two key improvements that deliver a dramatic boost to designer productivity. This latest release includes a flexible multicore processing technology that makes more effective use of both single-core and multicore CPUs across today’s compute server farms, better harnessing their compute potential. This release also introduces new runtime optimizations, allowing design engineers to run faster full timing and signal integrity (SI) analysis on their large designs early in the implementation process, thus reducing costly design closure iterations. These improvements work in concert to deliver up to 2X faster runtime and have been confirmed on a suite of leading semiconductor companies’ designs ranging in size from one million to 50 million instances.

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
