Wiring connections between components in PCB Design - Dashboard Guide

Dashboard Mode - Wiring connections between components

Goal

Understand how wiring connections between components affect the overall PCB design and signal flow.

Sample Data

Component	Pin	Connected To	Wire Length (mm)	Signal Type
U1	Pin1	R1 Pin1	15	Power
U1	Pin2	C1 Pin1	10	Signal
R1	Pin2	U2 Pin1	20	Signal
C1	Pin2	GND	5	Ground
U2	Pin2	LED1 Anode	12	Signal
LED1	Cathode	GND	8	Ground

Dashboard Components

• Total Wire Length (mm): Sum of all wire lengths.
  Formula: =SUM([Wire Length (mm)])
  Result: 70 mm
• Signal Wire Length: Sum of wire lengths where Signal Type = 'Signal'.
  Formula: =SUMX(FILTER(Table, [Signal Type] = "Signal"), [Wire Length (mm)])
  Result: 42 mm
• Power Wire Length: Sum of wire lengths where Signal Type = 'Power'.
  Formula: =SUMX(FILTER(Table, [Signal Type] = "Power"), [Wire Length (mm)])
  Result: 15 mm
• Ground Wire Length: Sum of wire lengths where Signal Type = 'Ground'.
  Formula: =SUMX(FILTER(Table, [Signal Type] = "Ground"), [Wire Length (mm)])
  Result: 13 mm
• Wire Length by Component: Bar chart showing total wire length connected to each component.
  Calculation: Sum of wire lengths grouped by Component.
  Example data points: U1=25 mm, R1=20 mm, C1=5 mm, U2=12 mm, LED1=8 mm
• Connection Table: Table listing each connection with Component, Pin, Connected To, Wire Length, and Signal Type for detailed view.

Interactivity

A filter for Signal Type allows users to select one or multiple signal types (Power, Signal, Ground). When applied:

• KPI cards update to show sums only for selected signal types.
• The bar chart updates to show wire lengths for components connected by the selected signal types.
• The connection table filters rows to show only connections matching the selected signal types.

This helps focus on specific wiring categories and analyze their impact on the PCB design.

Self Check

Question: If you add a filter to show only Signal type wires, which components have wire lengths shown in the bar chart?

Answer: Components U1, R1, and U2 will show wire lengths because they have connections with Signal type wires.

Key Result

Dashboard shows total and categorized wire lengths between PCB components with interactive filtering by signal type.
