Why routing connects the circuit physically in PCB Design - Dashboard Impact

Dashboard Mode - Why routing connects the circuit physically

Goal

Understand how routing physically connects components in a circuit to ensure electrical signals flow correctly.

Sample Data: Circuit Components and Connections

Component	Pin	Connected To	Signal Type
Resistor R1	Pin 1	Capacitor C1 Pin 1	Analog
Capacitor C1	Pin 2	IC U1 Pin 3	Analog
IC U1	Pin 3	LED D1 Anode	Digital
LED D1	Cathode	Ground	Digital
Power Supply	VCC	IC U1 Pin 1	Power
IC U1	Pin 1	Power Supply VCC	Power

Dashboard Components

• KPI Card: Total Components - Counts all unique components in the circuit.
  Formula: COUNTROWS(DISTINCT(Components[Component]))
  Result: 5
• KPI Card: Total Connections - Counts all physical connections (routes) between pins.
  Formula: COUNTROWS(Connections)
  Result: 6
• Bar Chart: Connections by Signal Type - Shows number of connections per signal type (Analog, Digital, Power).
  Formula: GROUPBY(Connections, Connections[Signal Type], "Count", COUNTROWS(CURRENTGROUP()))
  Result: Analog=2, Digital=2, Power=2
• Network Diagram: Physical Routing Map - Visualizes components as nodes and routes as edges showing physical connections.
  Data: Uses Components and Connections tables.
  Purpose: Demonstrates how routing physically links pins to complete the circuit.
• Table: Connection Details - Lists each connection with source component/pin and destination component/pin.
  Data: Connections table as shown in sample data.

Interactivity

Filter by Signal Type: Selecting a signal type (Analog, Digital, Power) updates the bar chart, network diagram, and connection details table to show only those connections.

Search Component: Typing a component name filters the network diagram and connection details to show routes involving that component.

Self Check

If you add a filter for Signal Type = Digital, which components update?

• The bar chart will show only the count for Digital connections.
• The network diagram will display only nodes and routes involved in Digital signals.
• The connection details table will list only connections with Digital signal type.
• The KPI cards remain the same as they count all components and connections overall.

Key Result

Dashboard shows how routing physically connects circuit components by visualizing connections, counts, and signal types.
