4.6. Electrical Rules Check tool

The icon gives access to the electrical rules check (ERC) tool.

This tool performs a design verification and is particularly useful to detect forgotten connections, and inconsistencies.

Once you have run the ERC, Eeschema places markers to highlight problems. The diagnosis can then be given by left clicking on the marker. An error file can also be generated.

4.6.1. Main ERC dialog

Errors are displayed in the Electrical Rules Checker dialog box:

• Total count of errors and warnings.
• Errors count.
• Warnings count.

Option:

• Create ERC file report: check this option to generate an ERC report file.

Commands:

• Delete Markers: to remove all ERC error/warnings markers.
• Run: to perform an Electrical Rules Check.
• Close: to exit this dialog box.

Note:

• Clicking on an error message jumps to the corresponding marker in the schematic.

4.6.2. ERC options dialog

This tab allows you to establish connectivity rules between pins; you can choose between 3 options for each case:

• No error
• Warning
• Error

Each square of the matrix can be modified by clicking on it.
