Hello Everyone, This is Daniel Esmaili
I am an electrical engineer at Ozen Engineering, Inc., an ANSYS ELITE channel partner. Today, I'm going to talk about crosstalk and zero scan using SI-WAVE, a great product from ANSYS.
Presentation Overview
In this presentation, I will cover:
- Verifying the PCB and showing the workflow result.
- Displaying the impedance scan and zero scan results.
- Discussing crosstalk in both frequency and time domains.
We can either execute these projects for you or train you to use the software to take advantage of these features. Please do not hesitate to contact us if you have any questions. At the end of this presentation, I'll provide more information about our company.
Step 1: Verifying the PCB
We use a wizard called the SI-WAVE Workflow Wizard. Here's a brief overview of the process:
- Import the ECAD file.
- Verify each step using the wizard. Errors are flagged by the software, helping us understand any issues.
- Utilize the auto-identify feature for power, ground, and net classification.
- Once verified, a green check mark appears next to each step.
Impedance Scan
After verifying the PCB, we proceed with the impedance scan:
- Access the simulation tab and select the impedance scan (Z0 scan).
- Choose the nets and adjust the nominal impedance and thresholds.
- Launch the scan and review the results, which display trace impedance across different layers.
Crosstalk Scan
The crosstalk scan can be conducted in both frequency and time domains:
Frequency Domain
- Set thresholds for far-end and near-end crosstalk.
- Launch the scan and visualize results, identifying areas of violation or warnings.
Time Domain
- Define driver and receiver types, rise time, voltage, and impedance.
- Launch the scan and review voltage values for far-end and near-end crosstalk.
Conclusion
We are a live channel partner of ANSYS, specializing in physics simulation to solve multidisciplinary engineering problems. Our expertise includes finite element analysis, CFD, and electromagnetics.

Thank you for your attention, and we hope you found this presentation useful.
Title: Crosstalk and Z0 Impedance Scan using SI-Wave Hello everyone, this is Daniel Esmaili. I am an electrical engineer in Ozen Engineering Company. We are an ANSYS ELITE channel partner and today I'm going to talk about the crosstalk and zero scan using SI-Wave, a great product of ANSYS.
In this presentation, I'm going to talk about how we verify the PCB first and show the workflow result, then show the impedance scan and zero scan result. We can do this type of project for you or train you to use the software to take advantage of these great features.
Please do not hesitate to contact us if you have any questions. At the end of this presentation, I'll provide more information about our company. The first step is verifying, and we use a wizard called the SI-WAVE workflow wizard. I imported the ECAD file, and now I need to verify each item.
Once I click on any of them, I need to verify the details, most of which are done by the software. If there is an error, the software will alert us. An additional benefit is the auto-identify feature in SI-Wave for power and ground net classification.
If there is a mistake, you can click it and move the nets up or down using the arrows. Once we go through this wizard one by one, we will see a green checkmark next to each item, indicating it has been successfully verified. Then, we start doing the impedance scan.
To do this, go to the simulation tab and click on impedance scan or Z0 scan. Choose the nets, adjust the nominal impedance and validation threshold, and click launch. The results will be shown in a new window.
In the results window, you can right-click on impedances and select 'display trace impedance.' This will display the impedance values for each net. If you have multiple layers, you can display the impedance for each layer. Hover your mouse over any trace to see its specific impedance value.
Next, I will show you the crosstalk scan. In the software, click on the crosstalk scan tab. Set the time domain and adjust the threshold values for far end, near end, or next for fuel. Once updated, click launch.
The crosstalk scan result will pop up, and you can right-click on it for different viewing options. We are an ANSYS ELITE channel partner, and we provide physics simulation to solve multidisciplinary engineering problems.
We have expertise in finite element analysis, CFDs, and high and low-frequency electromagnetics. If you would like to use the software or have questions, please feel free to reach out at support@ozeninc.com. We do simulation in different areas and would be happy to help you with any projects.
Thank you for watching, and I hope you found this presentation useful.
