Tech Tip: How to Design a Single-Point Ground or “Star Point Component”

A single-point ground, often called a “star point component,” is a crucial design technique in electrical layouts. It involves creating a controlled short-circuit between two points of different electrical potentials, improving signal integrity, and reducing noise in complex circuits.

What is a Single-Point Ground?

This method connects specified nets within a layout design at a single point, known as the “star point.” This point, where different nets converge, is represented by a component pin known as a “star point pin.”

The Role of the Star Point Component

A component that includes this special pin is called a “star point component.” The star point pin acts as the common ground, ensuring all nets connect at a single, controlled location.

How to Set Up a Star Point Component

To implement this in your design, follow the steps outlined in the video below. This tutorial, recorded in CR-8000 V2023, covers the detailed setup process for creating a single-point ground.
