Why advanced routing handles high-speed signals in PCB Design - Dashboard Impact
Sample Data: PCB Signal Routing Parameters
| Signal ID | Length (mm) | Impedance (Ohms) | Cross Talk (dB) | Signal Speed (Gbps) | Routing Type |
|---|---|---|---|---|---|
| S1 | 50 | 50 | -40 | 1 | Basic |
| S2 | 75 | 45 | -30 | 2.5 | Basic |
| S3 | 60 | 50 | -50 | 3 | Advanced |
| S4 | 80 | 48 | -45 | 5 | Advanced |
| S5 | 55 | 52 | -35 | 1.5 | Basic |
| S6 | 70 | 50 | -48 | 4 | Advanced |
Dashboard Components
- KPI Card: Average Cross Talk (dB)
Formula: Average Cross Talk for Basic vs Advanced Routing
Basic Routing: (-40 -30 -35) / 3 = -35 dB
Advanced Routing: (-50 -45 -48) / 3 = -47.67 dB - Bar Chart: Signal Speed vs Cross Talk by Routing Type
X-axis: Signal Speed (Gbps)
Y-axis: Cross Talk (dB)
Bars grouped by Routing Type (Basic, Advanced)
Shows that Advanced routing maintains lower cross talk at higher speeds - Table: Signal Details
Shows all signals with Length, Impedance, Cross Talk, Speed, and Routing Type

Interactivity
Filter by Routing Type (Basic or Advanced) updates KPI card, bar chart, and table to show only selected routing signals.
Filter by Signal Speed range updates bar chart and table to focus on specific speed ranges.
Self Check
Add a filter for Routing Type = Advanced. Which components update?
- KPI Card updates to show average cross talk for Advanced routing only (-47.67 dB).
- Bar Chart updates to show only Advanced routing signals.
- Signal Details Table filters to show only Advanced routing rows (S3, S4, S6).
Key Result
Dashboard compares signal quality metrics between basic and advanced PCB routing for high-speed signals.
