DS90UB954-Q1: Gap between Si analysis and actual machine measurement

Hi team,

We observe the waveform of the actual board and compare it with the simulation results we performed in advance.

Although it was not seen in the simulation, the result that seems as reflection in the actual board is prominent

The probe was modeled, but can you give me advice on what is affecting it?

If possible, I would like to discuss offline to send the environment and waveforms.

Best regards,

Hi Yoshida-san,

Was the simulation only done on the PCB traces themselves? If components and the connector are mounted on the actual board, the simulation results can be off. Feel free to send me your setup and waveforms in a private message.

Best,
