Clearance rules for different nets in PCB Design - Dashboard Guide

Dashboard Mode - Clearance rules for different nets

Dashboard Goal

Understand and compare clearance rules applied to different nets in a PCB design to ensure proper spacing and avoid electrical shorts.

Sample Data: Clearance Rules by Net

Net Name	Net Type	Minimum Clearance (mil)	Maximum Clearance (mil)	Standard Clearance (mil)
Power	High Current	10	20	15
Signal_A	Signal	5	10	7
Signal_B	Signal	6	12	8
Ground	Reference	8	15	12
Clock	High Speed	7	14	10
Reset	Control	5	9	7

Dashboard Components

• KPI Card: Average Minimum Clearance
  Formula: Average of 'Minimum Clearance (mil)' column.
  Result: (10+5+6+8+7+5)/6 = 6.83 mil
• Bar Chart: Minimum Clearance by Net
  X-axis: Net Name
  Y-axis: Minimum Clearance (mil)
  Shows clearance needed for each net.
• Table: Clearance Details
  Shows all columns from sample data for detailed comparison.
• Line Chart: Clearance Range (Min to Max) by Net
  X-axis: Net Name
  Y-axis: Clearance (mil)
  Lines show min and max clearance for each net to visualize range.

Interactivity

Filter by Net Type to update all components:

• KPI card recalculates average minimum clearance for selected net types.
• Bar chart updates to show minimum clearance only for filtered nets.
• Table filters rows to show only selected net types.
• Line chart updates clearance ranges for filtered nets.

All components respond to the same filter to maintain consistent analysis.

Self Check

If you add a filter for Net Type = Signal, which nets remain and how do components update?

• Nets remaining: Signal_A and Signal_B.
• KPI card shows average minimum clearance: (5 + 6)/2 = 5.5 mil.
• Bar chart shows minimum clearance bars for Signal_A and Signal_B only.
• Table shows only rows for Signal_A and Signal_B.
• Line chart shows clearance ranges for Signal_A and Signal_B.

Key Result

Dashboard shows clearance rules for different PCB nets with average, detailed table, and visual range comparison.
