Impedance analysis

Impedance analysis boosts device performance by managing signal distortion. For optimal high-speed design performance, manage and control the impedance for every critical signal throughout your board.

1. On the PCB Simulation toolbar, click Analyze Signal .
2. Select a signal from the list of signals on the board.
3. Specify the desired frequency.
4. Specify the target impedance (Z0).
5. Specify, as a percentage of the target impedance, the tolerance value that makes up the acceptable impedance range.
6. Click Analyze Signal. The results display in the area below the input boxes.
7. Use the drop-down menu to switch between analysis modes.
8. Select Impedance.

The 7-color scale displays the Impedance levels. The minimum and maximum values on this scale correspond to the range of results for the selected signal.

1. A color swatch in the results column shows Impedance. By default, Fusion arranges in descending order. If needed, you can change the order using other columns.
2. Review analysis results and make appropriate adjustments. Double-clicking a path or segment zooms the canvas to the extent of the object.
3. (Optional) To access more settings, click the Gear icon in the Action bar.
4. (Optional) To toggle canvas overlay display, click either the Impedance or Coupling.
