Synopsys Icc User Guide Pdf

Building the clock tree, buffering, and routing to meet timing and skew requirements. 5. Routing Global Routing: Analyzing routing feasibility.

Distributes cells globally without considering overlaps. Legalization: Shifts cells to valid rows and grid sites.

While in the icc_shell , you can type man for instant help on specific Tcl commands.

The software installation directory typically contains a /doc folder with all relevant PDF guides. 6.

It's also important to know the successor tool: . ICC2 uses the NDM data model and a distributed multi-threaded architecture for faster runtime on large designs. Many guides are available for ICC2 as well.

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).

The of your design (Floorplanning, Placement, CTS, or Routing) Building the clock tree, buffering, and routing to

Running the place_opt command to perform timing-driven and power-driven placement. 3. Clock Tree Synthesis (CTS)

While ICC performs internal timing analysis, you should run PrimeTime via a concurrent session for sign-off verification. Use the report_timing command within ICC to verify setup and hold slacks:

Specifically engineered to handle multi-corner multi-mode (MCMM) optimization for sub-7nm FinFET and advanced-node designs. Distributes cells globally without considering overlaps

Define clock waveforms, input/output delays, and false paths. Stage 2: Floorplanning and Power Planning

Synopsys keeps its official manuals secure to protect its software. You cannot usually find them through a standard Google search.

Before any placement or routing can occur, the tool requires accurate design data. The user guide outlines how to set up the design library using the database (for classic ICC) or the NDM (New Data Model) library format (for ICC II). It covers: Importing the gate-level netlist (Verilog).
