Crash Course: Induced Voltage Analysis Using SIwave and AEDT Circuit
Step 1: Upload Your PCB
Start by uploading your PCB. Click on the icon to view all the five types that SIwave can support, especially IPC 2581 and ODB++.
Step 2: Access the SIwave Wizard
Click on the orange icon to access the SIwave wizard and select Configure PI Analysis.
Step 3: Induced Voltage Analysis Setup
To perform induced voltage analysis, you need to set up ports:
- Select a power plane, an RF line, or a group of them.
- Assign ports to these selections. For example, place a port on the VRM and another on the CPU to study the coupling field between these two ports.
After configuration, validate the setup. If everything is correct, close the configuration window but do not simulate yet.
Step 4: Simulation
Proceed to the simulation step:
- Click on Compute Induced Voltage.
- Specify your frequency band and the number of frequencies.
- Define the field impacting your PCB, including direction (phi and theta) and polarization. You can specify multiple fields and their normalized polarization magnitudes.
- Launch the simulation.
Step 5: Analyze Results
Once the simulation is complete, review the results:
- Plot the induced voltage on the selected ports.
- View the results in the electronic desktop to see the voltage levels at each port.

Click the orange icon to access the SIwave wizard and select "Configure PI Analysis." To perform induced voltage analysis, select a power plane, RF line, or a group of them and assign ports. Place a port on the VRM and another on the CPU to study how much field is coupled to these two ports.
Click "Configure," then "Validate" to ensure everything is correct. Close both windows and do not simulate.
Next, go to "Simulation" and click "Compute Induced Voltage." Specify your frequency band, number of frequencies, the field hitting your PCB (direction: phi and theta, polarization, magnitude of the normalized polarization), and launch.
Review the results, plotting the induced voltage on both ports to view the voltage at each port on the electronic desktop.
