Here is a list of some of the important updates made to Tempus^TM Timing Signoff Solution and Voltus^TM IC Power Integrity Solution for the 20.1 production release:  

Tempus

• Tempus Power Integrity Solution Introduced
  The Tempus Power Integrity (Tempus PI) solution integrates the Tempus and Voltus solutions to: 
  
  - perform IR-aware timing analysis and failure fixing
  - reduce IR drop margins to improve power and area
  - utilize proprietary vectorless-based algorithm to identify critical paths most likely impacted by IR drop
  For detailed information about Tempus PI, refer to the Tempus User Guide on Cadence Support portal.
  
  
• Enhanced Support for Integrated Signoff Closure
  Tempus Signoff ECO now has the capability to perform DRV, Setup, Hold, and Power Optimization together in the path-based analysis (PBA) mode. This functionality is available through the Innovus cockpit. The new flow enhances user experience by providing easy-to-use Tempus ECO solution. It results in fewer iterations for improving power, performance, and area (PPA). 

For more details about the new and enhanced features introduced in this release, see Tempus What's New.

Voltus

• New XP Processing Mode to Achieve Large Capacity and Scalable Performance
  Voltus introduces the new Extensively Parallel (XP) mode aimed at providing performance improvements of up to 5X, making it easier to work on giga-scale designs. The XP mode enhances the Voltus solution's massively parallel execution with more efficient scalability on thousands of CPUs and hundreds of machines.
  For detailed information about the Voltus-XP technology, refer to the Voltus User Guide on Cadence Support portal.
  
  
• Tempus Power Integrity Flow for IR-Sensitive Path Prediction
  The new Tempus Power Integrity (Tempus PI) flow provides a better solution to find and fix IR-sensitive timing paths that result in timing failures. This flow accurately predicts IR drop on the critical paths with Voltus vectorless analysis, and enables automated fixing using Innovus and Tempus IR-ECO. 
  For detailed information about Tempus PI, refer to the Voltus User Guide on Cadence Support portal.
  
  
• Simplification of the Vector Profiler Flow
  The use model of the Vector Profiler flow has been simplified and streamlined for easy adoption and better usability. 
  For detailed information, refer to the Voltus What's New document on Cadence Support portal.
  
  
• Combined Vector Profiling and Dynamic Power Analysis for Multiple Windows
  Supports combining vector profiling and dynamic power analysis to identify windows with maximum activity to further drive dynamic vector-based power analysis.
  For detailed information, refer to the Voltus User Guide on Cadence Support portal.

For more details about these and all the other new and enhanced features introduced in this release, see Voltus What's New.
