Execute localized search-and-repair iterations: route_detail -incremental true . 6. Essential ICC/ICC II Command Reference Cheat Sheet

Jamie’s block taped out two days early, clean. Alex needed a three-day extension and still had to ECO-fix 50 timing paths manually.

Add filler cells to maintain well continuity and density rules. Export the design via GDSII or OASIS formats. 3. Essential ICC Command Reference Cheat Sheet

: Automatically positioning standard cells within the floorplan rows while optimizing for area, timing, and congestion. Clock Tree Synthesis (CTS)

Coarse placement, high-fanout net synthesis (HFNS), and legalization.

If an execution crashes abruptly, the physical database may lock or corrupt. Always use check_library and save checkpoint design cells ( save_mw_cel -as stage_name ) at every major milestone of your run script. 6. Accessing Official Documentation and PDFs

Choose an existing block, often denoted as a .dlib file (e.g., ORCA_TOP.dlib ).

Until this point, clocks are treated as ideal networks. CTS builds a physical buffer tree to distribute the clock signal evenly to all sequential elements.

Adjust cell density parameters ( set_congestion_options ) to prevent the placement engine from packing cells too tightly in complex areas. Low Power Optimization

The optimization engine dynamically evaluates constraints across all active scenarios simultaneously to ensure a fix in one mode doesn't break timing in another. Design for Manufacturability (DFM)

Aligns cells precisely to the site rows without overlaps.

Using the start_gui command to launch the visual interface. 3. Getting Started with ICC2 Shell

Chips must perform reliably across extreme operating points—ranging from ultra-low temperatures with high voltage (fast corner) to high temperatures with depressed voltage (slow corner).
