SoC Integration & Design Restructuring

Reaching power, performance and area (PPA) requirements for complex SoCs is becoming a real challenge. Restructuring an SoC design by building multiple variants of the same SoC with different PPA scenarios is often needed. STAR provides a complete and powerful automation platform to restructure complex SoCs.

Flow Design Restructuring and SoC Integration

 

High Level Benefits

 Reduce design cycles – From months to days

Save Area – Between 5 to 10%

Reduce simulation time – Between 4 to 10X

Increase IP reuse ratio

 

Typical Applications

Top Level Generation

 

Flow SoC Integration

  • IP Insertion
    • Early start
    • Ability to parameter instances
    • Ability to insert comments
    • Built-in Excel API
    • IPXACT support
  • Monitor SoC integration progress real-time
    • Report unconnected blocks/pins
    • Report clamped pins
    • Report overall connectivity status
  • Automated connectivity insertion
    • By naming convention
    • By configuration file (ie: xls)
    • Attribute/Interface based
    • Ability to clamp pins and to add glue logic

 

Design Restructuring

 

 

  • Split the top level in smaller hard macros
  • Maximize IP reuse
  • Layout density improvement
  • Power-Aware RTL Design Restructuring
  • Implement inter-block connections
