Patent addresses fundamental principles for threaded static timing analysis

CLK Design Automation Inc today announced that it has been awarded U. S. Patent 7793243 for Multi-Engine Static Analysis. The patent covers CLK Design Automation’s core technology for threaded and distributed static timing analysis.

"The award of this patent establishes our technology leadership position for threaded and distributed static timing," said Isadore Katz, President and CEO of CLK Design Automation. "This patent covers the core fundamentals of any modern static timing solution that incorporates parallel processing, and integration of the results into a shared database."

CLK Design Automation uses these methods throughout Amber, an integrated suite of static analysis tools for high-performance, cell-based designs. Amber is being used in production on some of the largest and most advanced circuits in design today. Users can analyze bigger circuits faster and more completely, and then isolate problems to make trade-offs and trial solutions in a fraction of the time it takes today.

Amber Path FX leverages this patented technology to deliver accurate, fast, and practical solutions for high accuracy timing of nanometer designs. Amber Path FX uses transistor level statistical static timing analysis (TSSTA) to achieve near SPICE accuracy for both delay and variance. With its multi-threaded simulator, Amber Path FX can evaluate thousands of paths per processor per hour (vs. days per path in SPICE).
