Timing Constraints Editor User Guide

Libero SoC v2025.1

Introduction to the Timing Constraints Editor

The Timing Constraints Editor, part of the Libero SoC Design Suite v2025.1, is a powerful tool designed to help users create, view, and modify timing constraints for their digital designs. This guide provides a detailed walkthrough of its features, enabling users to effectively manage timing requirements and exceptions to ensure optimal design performance.

Key Features and Functionality

The editor offers a user-friendly interface organized into several key areas:

Constraint Browser: Categorizes constraints into Requirements, Exceptions, and Advanced settings, facilitating organized management.
Constraints List: Presents constraints in a spreadsheet format, allowing for detailed editing of parameters.
Constraints Adder: Provides intuitive methods for adding new constraints, either through a dedicated dialog box or direct entry.

Users can define various types of constraints, including:

Clock Constraints
Generated Clock Constraints
Input and Output Delay Constraints
Timing Exceptions such as False Paths and Multicycle Paths
Advanced constraints like Clock Latency and Clock Groups

The guide also includes a comprehensive reference for SmartTime Tcl commands, offering advanced control and automation capabilities for constraint management.

Getting Started

To begin using the Timing Constraints Editor, users can access it through the Libero SoC software. The guide outlines multiple methods for adding constraints, ensuring flexibility for different user preferences and workflows. For detailed instructions and examples, refer to the specific sections within this document.

For further assistance and support, Microchip Technology provides resources through its Microchip FPGA Support portal.
