Question Answer
Can we build this simulation on HFSS? Absolutely, you can build this simulation in HFSS. You just need to identify the discontinuities in the structure and assign appropriate ports based on the geometry and the operating frequency.
There are so many standards to evaluate crosstalk, such as ICN, ICR, and COM, … which one is suitable for analysis in the time domain or frequency domain? ICR is typically used for frequency domain analysis, derived from the insertion loss ratio to ICO. However, time-domain responses provide a more realistic representation of actual system behavior. COM, on the other hand, is entirely based on frequency domain analysis.
Can we use complete PCB to analyze more realistically? Yes, you can use a complete PCB model for a more realistic analysis. This allows for 3D and discontinuity analysis and evaluating trace behavior and overall system performance. However, it does require a robust system and additional time. The goal in interconnect design is to localize the effects, ensuring the structure neither radiates nor interacts with others. This can be accurately captured using decomposition analysis.
Is PowerSum Xtalk in dBm or dBmV? PowerSum Crosstalk is typically expressed in dB, not in dBm or dBmV.
How about a nonuniform microstrip line? Is it possible to analyze? Yes, a nonuniform microstrip line can be analyzed. By examining the impedance profile, you can observe variations along the trace. You can also define a discontinuity region around the nonuniform section for detailed analysis.
Is the demo file with multiple design cases available to download and play with different parameters? Yes, absolutely. Upon request, a Google Drive link will be provided where you can download the demo file.
