更新
Featured Enhancements
Here is a list of some of the important updates made to Tempus Timing Signoff Solution for the 20.2 production release:
Tempus
Tempus Power Integrity Flow
The Tempus Power Integrity Analysis (Tempus PI) solution provides the capability to run IR analysis that is timing-aware, and timing analysis that is IR-aware. The Tempus PI is a seamless integration of the Tempus static timing analysis (STA) and Voltus power and IR drop technologies.
Infinite Depth Path-Based Analysis (IPBA)
The Tempus software supports infinite depth path-based analysis (IPBA). This feature runs faster analysis (vs full depth exhaustive PBA (EPBA)) and attains PBA design coverage with no depth limit per endpoint.
SmartScope Supports Timing Context Models
The Tempus SmartScope feature allows you to perform timing analysis with block context models - which is a top-down hierarchical STA technique. The context model feature allows block timing/glitch analysis and closure with realistic constraints instead of pessimistic block budgeted constraints.
Large Number of Active Timing Views Using SmartMMMC
The Tempus software provides the ability to handle a large number of active timing views using the SmartMMMC feature. This feature is used to enable reduced memory and faster run time when many timing views are enabled during timing or power ECO fixing stage.
New Metal ECO Flow
A new Metal ECO flow, also called Post-Mask ECO, using the Gate Array filler cells has been introduced. In this flow, the timing closure engine performs the netlist change without touching the base layer mask.
