ECO Kits

The Engineering Change Order (ECO) extension library kits give designers the flexibility to create logic elements using metal only for cost-effective design changes. Designers can use these kits after a chip has been placed and routed to accommodate last minute product requirements or correct final verification issues.

Highlights
Features
  • Easy to Use
    • Standard design flow
    • More flexible than spare gates
    • Characterized cells replace randomly placed filler cells or DCAP cells
    • Can be clustered in special row or column areas
    • Characterized with same VTs, PVTs as base libraries
