Multimode Analyzer Leverages Power Of Multithreaded Platforms

Among the issues compounding design closure, none is more pressing than the timing, power, and signal-integrity (SI) loop. Timing tools have not scaled with design complexity. Runtimes for SI tools can stretch beyond 24 hours. With hundreds if not thousands of timing violations to clear in a given design before tapeout, tools must evolve to a higher level.

To take timing analysis to the next level of efficiency, CLK Design Automation's Amber Analyzer boasts an architecture that leverages multicore, multiprocessor compute platforms to execute analysis runs 10 times to 20 times faster than other timing analyzers (see the figure).

Everything in the tool's architecture is threaded, including engines, solvers, parsers, database management, and storage. The multimode analyzer digs into leakage power and statistical leakage power. There's also support for on-chip variation and statistical timing.

The Amber Analyzer addresses the need for fully incremental operation across all classes of analysis (timing, SI, and leakage) for any type of design change, including cell swaps, netlist modifications, constraints, or parasitics. Thus, a 50,000-cell swap on a 10 million-instance design takes less than three minutes to analyze for signal integrity. Further, the tool's incremental capability guarantees that the answer it delivers is the same as if the entire design had been run flat.

Turnaround time for incremental analysis is proportional to the size of the design change. So is the memory footprint for the analysis. As a result, incremental jobs can be run on desktop-class machines.

The Amber Analyzer runs on 32-bit and 64-bit Linux platforms and starts at $25,000 for a one-year license. An open C-based API lets users incorporate the analyzer into other tools.
