Hello,<\/p>\n

I’m new to Ansys SiWave and would appreciate some assistance.<\/p>\n

When defining a port for a pair of group pins (e.g., Vcc group and GND group), SiWave prompts you to set the reference impedance of the port. How does this reference impedance affect the results (e.g., SYZ solver)? I believe the reference impedance is only used for S parameter measurement as port termination for non-driven ports, as explained in the video below. Is this correct, and is it not used for Y and Z parameter measurements?<\/p>\n
