    How to display Object Properties on schematics? Reply

        Hi,

    I am new to Cadence Virtuoso Schematic Editor. I had a quick question.

    I have a user defined property on instances in my schematics. If I select the instance and press key 'q', it gives me a pop-up menu for 'Edit Object Properties'. There, I do see the property listed in the User Property section and having a Local Value assigned to it.

    However, the Display option next to it is off by default. I was wondering if there is a way to turn it on 'only' for this very property by default so that I don't have to go and change the 'Display->off' option to 'Display->value' by hand for every instance.

    Any help would be sincerely appreciated.

    Thank you.

    I would assume that such a user property would originate from its symbol. So, I will go and open the symbol of this instance and check in Edit->properties->Cellview

    I will turn on the value option for this particular property in question and check and save my symbol. Now, it should be visible for all instances.

    rairaj,

    Thanks for responding.

    I cannot edit the symbol since it is a cell from the stdcell library. So, that option seems tough.

    If I change the 'Display->off' option to 'Display->value' option in Edit Object Properties menu of that instance, then I do see the value getting displayed on the schematic. So, I was thinking that there is a way I can make this possible at the schematic level without editing at the symbol level.

    However, I do not know how to save the preference. I also do not know how can I make it the default Display option for all instances which have a certain value to this property.

    Thanks again.

    Load this code:

    procedure(CCSPropDisplay(cellname propName)
    let( (cv prop)
    cv = geGetWindowCellView()
    foreach(inst cv~>instances
    if(inst~>cellName == cellname
    then
    if(prop=dbFindProp(inst propName)
    then
    ;;check for existence of assocTextDisplay
    unless(prop~>assocTextDisplays
    dbCreateTextDisplay(prop inst list("device" "annotate")
    list("justify" "orient")
    list(xCoord(lowerLeft(inst~>bBox)) yCoord(upperRight(inst~>bBox)))
    "centerCenter" "R0" "stick" 0.0625)
    printf("\nCreated textDisplay Object")
    )
    prop~>assocTextDisplays~>isVisible =t
    )
    ) ;if
    ; dbSave(cv)
    ) ;foreach
    ) ;let
    ) ;proc


    Open your cellview. Call:

    CCSpropDisplay("mycell" "myprop")

    Replace "mycell" with actual cell whose props you are looking at and myprop is the property name.
