Faster Database Readiness for Physical Verification: With Calibre Design Enhancer PVR
DescriptionA significant bottleneck in modern physical design is the runtime performance of Place-and-Route (P&R) based filler and DCAP insertion. Current methodologies often require a full removal and reinsertion of fillers during every Engineering Change Order (ECO) cycle. Near tape-out, where multiple iterations are frequent, these excessive delays substantially increase Turnaround Time (TAT) and hinder final design convergence.

To address this, a core innovation has been developed: an OASIS-based filler/DCAP insertion methodology that integrates results back to the P&R environment via Incremental DEF. This flow offers user-controllable options for coverage percentages and filler-type selection—including multi-height and ECO-specific fillers—across diverse designs. Notably, the methodology scales effectively with design complexity; the larger the block or IP, the more significant the runtime benefits achieved, whereas smaller blocks see a more modest value proposition.

This Correct-by-Construction approach leverages signoff-level rule awareness to guarantee DRC-clean insertion, effectively eliminating manual ECO loops and improving predictability. By utilizing RealTime Digital TCL APIs, the flow ensures seamless integration and full compatibility with any standard P&R environment. This optimized approach provides a streamlined path to timing closure and drastically reduces overhead during critical design phases.
