output setup shows a yellow row

I can't find any reports of this specifically to do with the "maestro" output setup (is this Explorer or Assembler? a screenshot might help). Have you adjusted the fonts or font sizes?

I'm not really sure what you are referring to.

Hi Andrew,

This is screenshot of output setup in assembler. 

and the report in CIW as below.

I'm not sure that the hiCreateListBoxField messages are really related to the yellow highlights. I must admit I was trying to remember what produces these yellow highlights (I've forgotten, and it's a Friday afternoon...). Which IC sub-version are you using?

Andrew

Hi, the virtuoso version is IC618-64b.500.24.

Dear sjwprcker,

In reviewing your outputs setup screenshot, it appears the "yellow shaded rows" all contain or define your output name "Nout_PSD". This output is defined as getData("out" ?result "noise"). However, I also noticed this output is listed under (perhaps, my guess) outputs associated with a Transient Noise simulation. However, a Transient Noise simulation will not produce a results of type "noise". Therefore, unless you are also including a small-signal noise simulation, you will not find an analysis of type "noise" and your output Nout_PSD should produce an evaluation error in the results tab. Since it can not be evaluated, your outputs that depend on it (which are also in yellow shaded rows) cannot be evaluated.

Are you also performing a small-signal noise analysis?

The expressions aren't related to transient noise, but instead using a noise analysis in the actimes in a tran analysis. Each of the expressions is retrieving the noise results from a specific time during the transient.

I can reproduce the problem (the hiCreateListBoxField messages are for something else). The yellow highlights indicate that there's a signal referenced in the output which does not exist - which isn't surprising, since out is the name of the output noise, not a signal. The dependent expressions get similarly tagged yellow.

Attempting to edit the expressions afterwards gets very messed up. I'll check to see if there's a CCR on this, and if not, I'll file one.

A workaround I found was to delete the Nout_PSD output, save the maestro view, close it, and then re-open and add Nout_PSD with the expression VN2() which will retrieve the output noise in V^2/Hz.

Hi Andrew,

I understand the yellow highlights coming from the non-signal output. Just be curious that if this is a new feature? I do remember not see such phenomenon before. And why it doesn't display when we run normal noise sim? In that case, out is still not physical output signal, right? Why it is only shown in actime based noise simulation?
