Cadence® Encounter® RTL Compiler Advanced Physical Option delivers real physical interconnect timing to the logic synthesis environment. Its high-capacity global synthesis, combined with the Encounter Digital Implementation System’s production placement engine, helps logic design teams easily predict, visualize, and fix physical issues that affect closure on a project’s performance, power, and area intent. Encounter RTL Compiler Advanced Physical Option speeds physical design closure by improving predictability and convergence on silicon quality goals through a robust suite of physically aware (PA) features.

Features/Benefits
  • Improves predictability of physical design closure
    • Realistic interconnect timing in synthesis means that when goals are met in synthesis, they will also converge in physical design
    • Handoff of legal placement enables the physical design team to start with exactly the same model on which the logic design team signed off
    • Modeling routing congestion during synthesis at a higher level of abstraction helps structure logic to avoid actual congestion issues later on during the routing stage
  • Increases overall quality of silicon
    • Accurately focuses performance optimization on the truly timing-critical logic through register-transfer level (RTL) physically aware mapping (PAM)
    • Predicts and eases congestion in datapath-intensive designs by using physically aware structuring (PAS)
    • Reduces power consumption by eliminating the need to apply excessive performance margin
    • Lowers clock power without impacting timing/congestion by merging single registers into multi-bit registers through physically aware multi-bit cell inferencing (PA-MBCI)
    • Synthesizes at the physical partition level with abstracted physical interconnect timing for the broadest scope of optimization
    • Performs physical optimizations earlier in the implementation process for larger-scale improvements
    • Analyzes and fixes scan chain ordering inefficiencies and reduces ATPG compression/decompression congestion through physically aware DFT (PA-DFT)
  • Reduces schedule risk
    • Eliminates iterations between logic and physical design teams caused by large differences in interconnect timing models
    • Provides early insight into potential congestion issues that can occur during routing
  • Ease of use enables widespread adoption by logic designers
    • Utilizes the same synthesis use model and user interface to which logic designers are accustomed
    • Physical interconnect modeling gives logic designers early insight into problems physical designers will encounter, enforcing smarter RTL design
    • Increases communication between logic and physical design teams
