SYZ Example Study with SiWave (Ansys)
Hello everyone, this is Daniel Esmaili on behalf of Ozen Engineering, Inc., a channel partner of ANSYS. Today, I'm going to talk about SYZ parameter analysis. We have an example to show you, and I'll start with the content by checking the nets and details. Then, we'll discuss the setup of the port, identify differential nets, generate the ports, and analyze the results.
Checking the Nets and Details
At the beginning, we need to check the nets and details of the PCB board. SIwave is the software we're using for this study. SIwave has a validation check available, which goes through many details of the PCB and checks for errors. If there are any errors, such as disjoint nets or floating nodes, the software will attempt to fix them automatically. If some errors remain, we can address them manually. We recommend running the validation check multiple times to ensure there are no errors.
Study Board and Nets
This is the board we're going to study today. We've chosen two different nets: one is a short net, and the other is a T-shaped continuous net. We will plot the SYZ parameter on these nets.
Identifying Differential Nets
Next, we need to identify differential nets, extended nets, and power and ground nets. The software can automatically identify differential nets. Initially, there may be no differential pairs visible, but after using the auto-identify feature, a list of differential nets will appear. It's crucial to understand how to use the auto-identify feature effectively.
Generating Ports
We need ports to measure the SYZ parameter. There are three ways to generate ports:
- Generate ports on selected nets: Choose some nets and generate ports using the software.
- Generate ports on selected components: Select components of interest and place ports on them.
- Manual port generation: Manually place ports at desired locations.
Running SYZ Parameter Analysis
Once the ports are generated, we run the SYZ parameter analysis. You can select any of the nets connected to your port to view the results. Additionally, we can plot this in the electronic desktop software.
About Ozen Engineering, Inc.
As I mentioned, I'm Daniel Esmaili, an application engineer at Ozen Engineering, Inc. We use multi-physics-based simulation to solve multi-disciplinary problems. If you have any questions or need services related to multi-physics finite element, computational dynamics, or high/low-frequency electromagnetics, please feel free to reach out to us. We are a channel partner of ANSYS.
Plotting and Analysis
We can plot the SYZ parameters and change the scaling from linear to logarithmic to see the differences. This approach helps us understand the S, Y, and Z parameters and study the circuit to identify any misalignments with the design.
Conclusion
I hope you found this information useful. Thank you for your attention.
Title: SYZ Example Study with SIWave (Ansys) Hello everyone. This is Daniel Esmaili, on behalf of Ozen Engineering, a channel partner of Ansys. I'm going to talk about SYZ parameter analysis today.
If you have an example, we're going to show you the following content: 1. Checking nets and details 2. Setting up the port 3. Identifying differential nets 4. Generating ports and analysis 5. Results First, we need to check the nets and details of the PCB board.
We're using SIWave for this study, which has a validation check available on the software. Once we hit that, it goes through the PCB's details and checks for errors. If there are any errors, such as joint net or floating node errors, the software can fix some of them, but not all.
We can use the software to fix as much as we can with the auto-fixing feature, and then do fixes manually.
Next, we run it again, and if there are no errors in the system, we recommend checking a couple of times, such as after the auto-fix and manual-fix, and then checking again to make sure there are no errors. This is the board we're going to study today.
We've chosen two different nets: one is shortened, and the other is a T-shape and a continuous net. We're going to plot the SYZ parameter on them. Once we do that, we need to make sure we identify the differential nets, extended nets, and power and ground nets.
We can use the auto-identify feature to help us with this. To generate ports, we have three ways: 1. Generate ports on selected nets 2. Generate ports on selected components 3. Do it manually Once we generate those ports, we run the SYZ parameter and show you the results.
We can plot this in electronic desktop as well. If you have any questions or need any service about multi-physics finite element or competition of dynamic or high frequency or low frequency electromagnetic, please feel free to reach out to us. We are a light channel partner of Ansys. Thank you.
