Title: Impedance setting for ports in Spectre Simulations
Post by jmedina on Nov 8^th, 2006, 1:40pm

Be aware, when using ports in Spectre simulations, a real and imaginary impedance can be defined in the properties menu for the device. When a reactance is specified, this imaginary part is valid only when running small signal analyses like sp, ac, and noise. The reactance will give erroneous results if pss, psp, and pnoise analyses are run. We are reporting this to Cadence as an action item.

J,

The imaginary component of the port reactance should be valid for frequency domain
analysis. Have you tried Harmonic Balance PSS analysis(PSS with tstab=0)?

Best Regards,
