displaying custom text in a schematic info balloon when hovering over an instance

DerekH

Hi,

I've recently been playing around with info balloons in a schematic view. I was wondering, is it possible to display some pertinent text in a balloon when hovering over an instance?

Something like "This amplifier does such-and-such", so that someone else can hover over individual devices or instances and get information on what they're do. 

My apologies if there's already something else that does this.

Thanks

Derek

  • I know this is an old post I'm responding to, but I really like the idea Derek proposed here. It would avoid cluttering up the schematic with lots of permanent notes. If it is possible, can the info text also be set/read from within an Ocean script?

    There's no generic "info balloon" capability for schematics. Enhancement CCR 585834 (and a number of duplicates) is asking for this, but it's not been implemented so far. These requests were triggered when we added similar capability to the layout editor (which does have the ability to do this).

    The Annotation capability (where you can annotate schematic parameters, operating point parameters and so on) does offer the ability to show info balloons over the instance, but it's (mostly) limited to ADE simulation purposes. You could potentially  add a CDF parameter for your component and then have that displayed via the annotation mechanism, but it's not really designed for the purpose you are asking about.

    Regards,

    Andrew.

    Thanks for clarifying. Good to know it's already on an enhancement request list. The notion of adding a cdf parameter makes sense, but I don't think there is a direct way for e.g. users of a TSMC library of primitives to add cdf parameters to those components. Don't suppose you know any indirect ways ;-)...

    Theoretically you could define a new CDF parameter in user CDF so that it was only defined in memory (the actual values would get stored on the instances, so they would show up again in the next session when you re-defined the user CDF), and then annotate that. However, this is very clunky and rather sensitive to doing things like File->Refresh where you could unwittingly discard all the user CDF.

    Personally I probably wouldn't create a flow that depended on doing it this way. There's no other workaround that I can think of though if you really wanted to do this.

    Regards,

    Andrew.

    Agreed - and thanks for your assistance. I'll (patiently) wait for the enhancement request to materialize then. 

  • Hi,

    Do you where I can define what parameters to be displayed when hovering over an instance?

    With my current configuration the ref des and component value is shown when i hover over an component. It would be neat if I was able to add the footprint to that list.

    I thought I could reuse this post even if it is a bit old.

    Thanks,

    Alexander

    Alexander,

    Which tool are you using? "Ref Des" and "Footprint" sound rather PCB-centric terms so I'm guessing you may not be using Virtuoso...

    Sorry, I am using OrCAD Capture.

    Thanks,

    Hi Alexander,

    OK, in that case you're in the wrong forum. You should post this question in the PCB Design forum instead (we also ask you in this forum not to post on the end of old threads, and to provide tool and version details, which would spot this kind of posting in the wrong place).

    Kind Regards,

    Andrew
