Electrical Rule Checker (ERC)

Purpose:

Verify electrical schematic against logical and electrical rules

Detect potential problems in the schematic before the routing stage

Capabilities and Features:

Detect unconnected inputs and outputs

Verify power supply consistency of components

Detect signal conflicts (output-output, power-ground)

Check bus and differential pair integrity

Control electrical consistency of hierarchical blocks

Connections with Other Sections:

Directly integrated into Schematic Editor

Interacts with Component Library Manager to verify electrical characteristics

Connected with Circuit Simulator for preliminary functionality verification
