Allocates specific global routing channels to physical layout tracks.
Assigns nets to global routing bins based on resource availability. Track Assignment: Maps nets to specific layout tracks.
ICC automatically swaps standard cells between High-VT (low leakage, slower) and Low-VT (high leakage, faster) versions to hit timing targets without leaking excess power. 5. Troubleshooting Common ICC Errors

Execute clock_opt to build the tree and optimize post-clock timing. Stage 5: Routing and Post-Route Optimization
To push modern designs to their performance limits, engineers must look beyond default scripts and utilize advanced optimization paradigms built into ICC. Multi-Corner Multi-Mode (MCMM) Scenarios

Logical/timing libraries (.db), physical libraries, technology files (.tf), and RC model files (TLU+).
This phase focuses on the initial layout, creating a "floorplan" for the design. The IC Compiler II Design Planning User Guide covers:
The official user guide structures its chapters sequentially, mimicking the standard physical design partition timeline. Below is the breakdown of the vital stages you will find detailed in the PDF.
: Executes Clock Tree Synthesis (CTS) , which balances clock delays across the chip to minimize skew and ensure signal integrity. ICC automatically swaps standard cells between High-VT (low
A typical Synopsys manual can easily exceed 1,000 pages of text, tables, and scripts. To study productively:
Position large IP blocks using automated macros or explicit coordinates via set_cell_location .
Once cells and clock trees are fixed physically, global and detail routers connect signal nets using available metal layers.
Synopsys IC Compiler integrates placement, clock tree synthesis (CTS), routing, and timing closure into a single, cohesive ecosystem. It native-links with Synopsys Design Compiler (synthesis) and PrimeTime (static timing analysis) to ensure maximum correlation and minimal timing violations. Key Capabilities
