Best-in-Class Quality-of-Results (QoR): Optimized for Power, Performance, and Area (PPA) across advanced nodes, including 7nm, 5nm, and sub-5nm.

Unified Optimization: Features a parallel framework for simultaneous clock and data optimization, reducing design closure time by weeks.

Golden Signoff Accuracy: Native integration with Synopsys PrimeTime for timing and StarRC for extraction ensures that what you see in the tool matches final silicon. The Physical Design Flow in ICC

The standard physical design flow typically follows these major stages: 1. Data Setup and Library Preparation

Before implementation begins, you must establish a "Design Library" (or Container).

Inputs Required: Logical/timing libraries (.db), physical libraries, technology files (.tf), and RC model files (TLU+).

Command: Launch the shell with icc_shell or icc2_shell and use start_gui to open the visual interface. 2. Design Planning and Floorplanning This stage defines the physical "home" for your logic. IC Compiler 1 Workshop

This guide provides a foundational overview of the Synopsys IC Compiler (ICC) physical design flow based on standard industry tutorials and official documentation. 1. Environment & Setup

Before launching the tool, ensure your UNIX/Linux environment is correctly configured with the necessary technology libraries and design files.

Startup Commands: Launch the tool using icc_shell. To enable the graphical interface, use icc_shell -gui or type gui_start within the shell.

Library Creation: Create a Milkyway (or NDM for ICC II) design library to store your design data using the create_mw_lib command.

Data Import: Load your synthesized Verilog netlist (import_designs) and read the Design Constraints file (read_sdc) to define timing requirements. 2. The Physical Design Flow

The standard flow follows a sequential path from floorplanning to final verification:

Floorplanning (create_floorplan): Define the core area, aspect ratio, and I/O pin placement. This stage establishes the physical boundaries of your chip. synopsys icc user guide pdf

Power Planning: Create power and ground networks. Common commands include derive_pg_connection for logical connections and create_rectangular_rings / create_power_straps for the physical mesh.

Placement (place_opt): Automatically place standard cells within the core while optimizing for timing and congestion.

Clock Tree Synthesis (clock_opt): Build the clock distribution network to minimize skew and insertion delay.

Routing (route_opt): Perform global and detailed routing to connect all signals. This is often the most time-intensive step.

Filler Cell Insertion: Fill empty gaps between standard cells to ensure electrical continuity using insert_stdcell_filler. 3. Verification & Export

Once routing is complete, you must verify the design before signoff.

DRC & LVS: Check for Design Rule Violations (verify_drc) and verify that the layout matches the schematic (verify_lvs).

Timing Analysis: Use report_timing at various stages to ensure the design meets its slack requirements.

GDSII Export: Export the final layout for manufacturing using write_stream. Additional Resources
