Design Fusion Common Technology Between Synthesis and P&R
Test Fusion Signoff Fusion ECO Fusion Enables Convergence, Fastest TTR e.g. Congestion . Synthesis P&R Synthesis Technology moves inside P&R for Best QoR Synthesis QoR inside P&R P&R QoR inside Synthesis Unified Optimization Strategy In addition, we are working on ‘Flexible Handoff’ from synt to P&R. This allows the front-end designers to go deeper into physical design – from netlist level all the way to legalized placement. Handoff can be of netlist, pre-legalized placement or legalized placement. May 1, 2018

Signoff Fusion PrimeTime, StarRC, PT-PX & RedHawk for Optimization AND Signoff
Test Fusion Design Fusion ECO Fusion Golden Sign-off Analysis in Optimization Zero Margin Platform Eliminates Pessimism With Signoff fusion, we are using PT and StarRC for signoff and for optimization across the flow. Industry golden signoff tech will be fused with implementation. The timing and analysis engines will be brought to synthesis and P&R. This enables perfect correlation. As a result, the platform becomes zero margin enabled. We are going to extend the backbone to IR and Thermal as well. Exclusive RedHawk Fusion Extends to IR, Thermal May 1, 2018
