Icc User Guide Pdf [best] — Synopsys

Essay: Navigating the Synopsys IC Compiler (ICC) Ecosystem The Synopsys IC Compiler (ICC) and its successor, IC Compiler II (ICC II), represent the industry standard for physical design and implementation in Very Large Scale Integration (VLSI). As modern System-on-Chip (SoC) designs grow exponentially in complexity, the IC Compiler User Guide serves as an essential roadmap for engineers to navigate the transition from a synthesized netlist to a production-ready GDSII layout. 1. The Core Physical Design Flow

The primary utility of ICC lies in its ability to execute a convergent, single-pass physical design flow. The user guide outlines three critical commands that drive the majority of the implementation process:

place_opt: Performs initial standard cell placement and simultaneous timing, area, and power optimization.

clock_opt: Executes Clock Tree Synthesis (CTS), which balances clock delays across the chip to minimize skew and ensure signal integrity.

route_opt: Manages global and detailed routing while performing final post-route optimizations to fix design rule violations and timing bottlenecks. 2. Advanced Features and Methodology

Modern versions like IC Compiler II are architected to handle massive designs with over 500 million instances using a highly scalable data model. Key methodologies detailed in the documentation include:

Design Planning and Floorplanning: Crucial for hierarchical designs where a flat layout is no longer feasible due to memory and runtime constraints.

Concurrent Clock and Data (CCD): An optimization engine that simultaneously analyzes clock and data paths to meet aggressive performance targets while minimizing the power footprint.

Signoff-Driven Closure: Integration with PrimeTime allows for golden-accuracy delay calculation directly within the ICC environment, significantly reducing the number of Engineering Change Order (ECO) iterations. 3. Practical Usage and Scripting synopsys icc user guide pdf

While ICC provides a robust Graphical User Interface (GUI) for navigating layouts and querying design objects, professional design environments rely heavily on the Tool Command Language (Tcl). The user guide emphasizes the importance of scripting to guarantee consistency across complex runs that can take hours or days to complete. Engineers use the icc_shell to execute these scripts, enabling automated design import, power grid creation, and final verification checks like Design Rule Checking (DRC) and Layout Versus Schematic (LVS).

Introduction to IC Compiler

Synopsys IC Compiler (ICC) is a comprehensive place and route solution for designing and implementing integrated circuits (ICs). It provides a powerful and flexible environment for designing, optimizing, and verifying complex digital systems. ICC is widely used in the semiconductor industry for designing and implementing System-on-Chip (SoC) designs. Essay: Navigating the Synopsys IC Compiler (ICC) Ecosystem

Key Features of IC Compiler

1. Place and Route: ICC provides a comprehensive place and route solution for designing and implementing ICs. It supports various design styles, including standard cell, gate array, and custom designs.
2. Design Optimization: ICC provides various optimization techniques to improve design performance, power consumption, and area.
3. Timing Analysis: ICC provides built-in timing analysis capabilities to ensure that designs meet required timing specifications.
4. Verification: ICC provides comprehensive verification capabilities, including design rule checking (DRC), layout versus schematic (LVS), and electrical rule checking (ERC).

Basic ICC Workflow

The following are the basic steps involved in using ICC:

1. Design Import: Import the design into ICC using a netlist or a HDL file.
2. Design Preparation: Prepare the design for place and route by setting up the design floorplan, defining design constraints, and specifying technology parameters.
3. Place: Perform the place step to position all design components on the chip.
4. Route: Perform the route step to connect all design components.
5. Optimization: Optimize the design for performance, power, and area.
6. Verification: Perform various verification checks to ensure design correctness.

ICC User Interface

The ICC user interface provides various tools and menus to access different features and functions. The main components of the ICC user interface are:

1. Menu Bar: Provides access to ICC menus and tools.
2. Toolbar: Provides quick access to frequently used ICC tools and functions.
3. Workspace: Displays the design floorplan and various design components.
4. Command Line: Allows users to enter ICC commands and scripts.

Common ICC Commands

Here are some common ICC commands:

1. icc_setup: Sets up the ICC environment and design parameters.
2. read_netlist: Reads a netlist into ICC.
3. place: Performs the place step.
4. route: Performs the route step.
5. opt_design: Optimizes the design for performance, power, and area.
6. verify_drc: Performs design rule checking (DRC).

If you are doing power gating, Chapter 11 (Power and Ground Routing) has the state transition table for Power Switches. Do not guess the PST syntax—copy it from here.

1. The Search is Your Friend

Never read the ICC User Guide cover-to-cover. It is a reference manual. Use Ctrl+F to find exact error messages. For example, search for Error: IMPSP-111 rather than "floorplan error."

D. DPT (Double Patterning) Rules

For 20nm and below, Chapter 14 details coloring constraints. If you ignore this, your design will fail mask verification.
