1 SSV Summit November 2013 Cadence Tempus™ Timing Signoff Solution

2 2© 2013 Cadence Design Systems, Inc. All rights reserved Signoff closure up to 40% of the design flow Need faster runtimes Capacity for +100M cell designs with 100s of timing views Better accuracy to reduce pessimism, power, area Industry needs for n ext g eneration signoff

3 3© 2013 Cadence Design Systems, Inc. All rights reserved The Tempus™ Timing Signoff Solution Tempus – It’s about TIME Up to 10X reduction in closure time Placement and routing aware Unlimited MMMC capacity Massively parallelized computation Scalable to 100s of CPUs Optimized data structures Up to 10X faster path-based analysis (PBA) Advanced process modeling TSMC-certified accuracy

4 4© 2013 Cadence Design Systems, Inc. All rights reserved Optimized multi-threading Distributed processing Incremental & hierarchical analysis Concurrent multi-mode multi- corner analysis Parallelized path based analysis Performance background Stacked performance enablement MMMC Concurrency MMMC Concurrency Incremental Analysis Distributed Processing Flat Single View (Multi-Threading) Technology

5 5© 2013 Cadence Design Systems, Inc. All rights reserved Combines multi-threading with distribution Simple setup –User specifies desired resources Parallelization transparent to user Up to 50M cells analyzed in one hour Low memory footprint Performance metrics Parallelized processing MMMC Concurrency MMMC Concurrency Incremental Analysis Distributed Processing Flat Single View (Multi-Threading)

6 6© 2013 Cadence Design Systems, Inc. All rights reserved Analyzes all modes and corners in one timing session Runs on one compute server More than 2X faster with same hardware –Less than 20% memory overhead per additional timing view Reduces hardware resource requirement Concurrent MMMC view analysis MMMC Concurrency MMMC Concurrency Incremental Analysis Distributed Processing Flat Single View (Multi-Threading)

7 7© 2013 Cadence Design Systems, Inc. All rights reserved Graph based analysis is fast but inherently pessimistic Path based analysis is slow but reduces pessimism –Accurate transitions and derates Tempus solves PBA reporting runtimes –Parallelized computation Path-based analysis (PBA) Reduced pessimism and runtime Pessimism reduction Pessimism reduction
