Probing All Currents in ADE Explorer / XL Without Inserting Components or Manual Selection

Hi,

Is there a way to save every single pin current so that I don't have to manually Save each one of them? I see a common issue where regardless of the Save Options settings, current will not probe unless you manually select the nets you want probed. Or unless you insert an analog component from analogLib, such as iProbe or Resistor. However, both these methods are unpractical and can become quite tedious for large circuits...

I've gone to

Outputs --> Save All, and
select "All" for "Select device currents",
Select AC Terminal Currents "yes"
Subcircuit Probe Level "4"

but still no luck.

Is there something I am missing or is this a known bug?

I don't know what version of spectre or spectreX you are using. There is an issue with spectreX that was addressed in a later release. This is detailed at URL:

Further, the following RAK addresses the various save statements and the means of invoking each. Options are detailed that include the number o hierarchies.

I hope this helps life.

Thanks Shawn but I can't view those links at the moment. Need to get an access code first. Can you summarize or send a screenshot?

Please follow through on obtaining an access code. You will find a tremendous amount of useful information within the Cadence On-line Support resource. Unfortunately, the Adobe versions of the two URL I provided can not be attached to this post.

You might also want to just set "subcktprobelvl" (although saving the current through every subckt pin at multiple levels of the hierarchy can be quite costly in terms of simulation time for a big circuit). In ADE you can also just click on the instance when selecting outputs to be saved to save the current through every pin of that instance.

Shawn's right though - getting access to support.cadence.com is a very good idea.
