Can't plot phase noise from pnoise result window in SpectreRF

Dear Cadence,

I followed the instruction manual to simulate phase noise
of a LC oscillator, I run the pss analysis and pnoise analysis.
Then, when I try to plot results of pnoise, I can plot
"Output Noise", however, when I chose "Phase Noise" it
says
"Output nodes of pnoise analysis not saved for pss analysis.
As a result, the above selected function cannot be executed."

I have restarted Cadence, redrew the schematic, set
Output->Save All... and checked "all" everywhere, but I still
cannot plot phase noise. What is my problem?

Best Regards,

Zhiheng

 

What version are you using (what does Help->About... in the CIW say)? I recall
this being a bug at some point in the past, which has been fixed.

I vaguely recall it being an issue if your output nodes contained odd
characters (such as "+" and "-"). If you stuck to alphabetic characters,
all was OK...

Andrew.
