Global placement involves assigning a design to a specific location on a board or sheet. This method is commonly used for placing components or symbols in a physical layout.
Detailed placement involves placing individual components or symbols at specific locations on the board or sheet. This method is often used for creating detailed mechanical parts or circuitry.
Here's a simple example to illustrate the difference:
Global Placement:
You have a board with a rectangle empty space.
You want to place a component in the center of the space.
You use a global placement method to assign the component to the center point.
Detailed Placement:
You have the same board with a detailed layout of a printed circuit board.
You need to place specific components on different tracks and components.
You use a detailed placement method to ensure each component is placed correctly.
Examples:
Global placement: When creating a printed circuit board layout, you might assign the entire schematic to the board.
Detailed placement: When building a mechanical part, you might place each screw and nut individually by hand
