Electrical Rules Check (ERC) in PCB Design - Dashboard Guide

Dashboard Mode - Electrical Rules Check (ERC)

Dashboard Goal

Check and analyze electrical rule violations in PCB design to ensure circuit safety and correctness.

Sample Data: ERC Violations Summary

Violation ID	Type	Severity	Net Name	Pin 1	Pin 2	Description	Count
V001	Short Circuit	High	GND	U1.1	U2.3	Unexpected connection between pins	3
V002	Open Circuit	Medium	VCC	U3.5	U4.2	Missing connection on power net	2
V003	Pin Conflict	Low	DATA	U5.7	U6.7	Multiple outputs driving same net	1
V004	Missing Power	High	RESET	U7.4		Pin not connected to power source	4
V005	Floating Pin	Medium	CLK	U8.2		Pin not connected to any net	2

Dashboard Components

• KPI Card: Total Violations
  Formula: SUM(Count)
  Result: 12
• KPI Card: High Severity Violations
  Formula: SUMX(FILTER(Data, Severity = "High"), Count)
  Result: 7
• Bar Chart: Violations by Type
  Data: Sum of Count grouped by Type
  Values: Short Circuit=3, Open Circuit=2, Pin Conflict=1, Missing Power=4, Floating Pin=2
• Table: Detailed Violations
  Shows all columns from sample data for detailed review

Interactivity

User can filter violations by Severity or Type using slicers. Filtering updates KPI cards, bar chart, and detailed table simultaneously to focus on specific issues.

Self Check

If you add a filter for Severity = High, which components update?

• KPI Cards update to show total violations and high severity violations only for filtered data (Total Violations = 7, High Severity = 7)
• Bar Chart updates to show counts only for high severity types (Short Circuit=3, Missing Power=4)
• Detailed Table shows only rows with High severity violations (V001 and V004)
