Synopsys Icc User Guide Pdf Here
Most people run place_opt and clock_opt blindly. The User Guide has a flowchart showing exactly when to use -incremental to save runtime.
Do not download documentation from unverified third-party sites. Synopsys documentation is proprietary and contains sensitive intellectual property regarding algorithms. The only safe and legal way to access these PDFs is via Synopsys SolvNet.
Why this matters: Synopsys updates command syntax frequently. A command found in a 2012 PDF might be deprecated or obsolete in the 2023 release.
The Synopsys IC Compiler (ICC) and its successor, IC Compiler II (ICC II), are the industry-leading solutions for physical implementation, covering everything from design planning to final signoff. The user guides for these tools are essential for mastering the complex flows of place-and-route (P&R). 📘 Core Documentation Overview
Synopsys provides several specialized guides depending on your stage in the design flow. You can find detailed versions like the IC Compiler™ II Multivoltage User Guide to manage complex power domains or the IC Compiler™ II Design Planning User Guide for early-stage floorplanning and hierarchy management. Key Manuals for Your Flow
Implementation User Guide (iccug): The primary manual describing the overall P&R flow.
Command Reference Guide: Detailed Tcl syntax for all ICC2 Useful Commands, such as report_timing and place_opt.
Multivoltage Flow Guide: Focuses on IEEE 1801 (UPF) support for low-power designs.
Data Model Guide: Explains the library and block structure used to store design data. 🚀 The IC Compiler Implementation Flow synopsys icc user guide pdf
The user guide typically breaks down the physical design process into several manageable phases: 1. Design Initialization
Library Setup: Loading technology files (TLU+) and physical libraries. Netlist Import: Reading the gate-level Verilog netlist.
Constraints: Applying SDC (Synopsys Design Constraints) for timing goals. 2. Design Planning & Floorplanning Defining the core and die area boundaries.
Placing macros (SRAMs, IPs) and creating power/ground rings.
You can learn the basics of this in an IC Compiler 1 Workshop module. 3. Placement & Optimization
place_opt: Automatically places standard cells while optimizing for timing and congestion.
Legalization: Ensuring all cells align perfectly with the site rows. 4. Clock Tree Synthesis (CTS)
clock_opt: Building the clock buffer tree to minimize skew and insertion delay. Most people run place_opt and clock_opt blindly
Post-CTS Optimization: Fixing hold time violations introduced by the new clock tree. 5. Routing
Global Routing: Planning the general path of wires to avoid congestion.
Detail Routing: Finalizing the metal traces using the Zroute engine to meet DRC (Design Rule Check) requirements. 🛠️ How to Access Official Guides
For the most up-to-date and authorized PDFs, you should use official channels:
SolvNetPlus: Synopsys' primary support portal. Registered users can access the Quick Guide to SolvNet to learn how to download the latest Synopsys Documentation.
man Pages: While in the icc_shell, you can type man for instant help on specific Tcl commands.
Learning Paths: Explore curated Synopsys Learning Journeys for structured training on IC Compiler II.
💡 Key Tip: Use the write_script command in ICC to export your current session's settings into a Tcl script. This is often more helpful for debugging than the general user guide alone! This is the most common confusion
Are you currently working on a flat or hierarchical design, and are there specific violations (like timing or DRC) you're trying to solve? I can help you find the specific commands or flow steps to address them.
This is the most common confusion. Synopsys discontinued the original IC Compiler (ICC) in favor of IC Compiler II (ICC2) around 2014-2016.
Before downloading any PDF, you must confirm which tool version you are using. They are related but fundamentally different, and using the wrong manual is the most common mistake beginners make.
Tip: If your script commands look like create_route_guide, you are likely in ICC II. If you are using derive_pg_connection heavily for older flows, you might be in classic ICC.
For 20nm and below, Chapter 14 details coloring constraints. If you ignore this, your design will fail mask verification.
While the official PDF is supreme, there are complementary resources:
Legally and officially, the ICC User Guide is distributed exclusively with a licensed Synopsys installation.
Warning: Be cautious of random PDFs on GitHub or public forums. Many are outdated (ICC vs. ICC2) or contain watermarks that violate NDAs.
