pnoise ignores "no noise" flag on resistors?

Hi,

I am measuring NFdsb for a simple voltage mode passive mixer using pss+pnoise Without any resistance I get NF=5dB. Now I shunt the input with R=50 for matching and NF increases to 10dB. While I am not sure about the numbers it makes sense due to additional noise of the matching resistor.

However, then I set "Generate noise?" to "No" but the result is still the same. I found then the flag "Suppress noise" which I checked too but still same results. In short: pnoise ignores the flag that I do not want to consider the noise from one resistor (this happens a lot, e.g. when the resistor is merely a modeling resistor such as ro).

Is this a bug? How can I turn off noise for a resistor for pnoise?

Thank you. Indeed, I have analogLib from Mentor. It seems to work now though for some strange reasons ... (keeping fingers crossed)
