Runs global/detail routing and performs post-route timing closure. report_timing
Balance the arrival time of the clock signal across the entire die.
Before running placement, ICC requires accurate physical and logical libraries. The guide outlines how to read in your gate-level netlist, logical libraries ( .db ), physical libraries ( .milkyway or Link logical/physical libraries in ICC2), and design constraints ( .sdc ). Phase 2: Floorplanning
What specific are you currently troubleshooting (e.g., Floorplanning, CTS, Routing)? synopsys icc user guide pdf verified
Verified commands: place_opt , psynopt , focal_opt . The user guide details how ICC performs congestion-driven placement. It also includes tables for pre-placement and post-placement optimization strategies.
This section teaches you how to initialize the core area, define die boundaries, place macros, create power rings/straps (PG synthesis), and establish pin placements to minimize congestion later in the flow. Phase 3: Placement and Optimization ( place_opt )
: This is the primary portal for qualified customers. It requires a registered username and password to download official manuals, including the latest IC Compiler II Design Planning User Guide . The guide outlines how to read in your
The final stage ensures the layout is physically ready for manufacturing and fully meets timing requirements across all operating corners. Key Sign-off Steps
This chapter guides you through defining the core boundaries, creating voltage areas, placing macros, and allocating I/O pins.
ICC relies on the Milkyway database, whereas ICC2 uses a highly scalable, multi-threaded polymorphic data model called the NDM (New Data Model) . The user guide details how ICC performs congestion-driven
Once components and clock networks are fixed, the router connects the signal pins using metal layers while adhering to strict foundry manufacturing rules.
