Need function to find the parameter names on objects in layout: ASAP

If  you need an urgent response, you should contact customer support. These forums are covered by volunteers in the community (even though I respond a lot - it's not part of my job at Cadence to respond to questions here).

It wouldn't be axlDBGetProperties as that's an Allegro (PCB tools) function.

The fact that you have an engineering hotfix build would suggest to me that you're a mainstream customer - so please go to customer support. That is what it's for! I don't have ICADV12.2 on my local machine (I'm not in the office) so I can't test this (nor do I have the bandwidth today anyway).

Andrew.

Hi Andrew... I am actually a contractor, so I do not have that access to the support, which is why i am asking here. Thanks anyway for replying

I'm sure you can get access to support even if you get somebody in the company you're contracting to to log the case.

Andrew.

Not to go into details due to my confidentiality agreement ...but, really... that is not possible. All I need is the skill function name for retrieving the parameter names... not fully written program. My question was not directed to you specifically, but to the entire board in hopes I could get a little help, which was what i thought this forum was for. . If you're to busy to look into it, I understand, perhaps someone else can chime in if they know the answer. Otherwise I'll just keep on trying myself.

I wrote a convenience function that I assign to a bindkey to help me quickly get some information. If I select an object and run this function, then the following happens:

The cellview ID is assigned to variable cv.
The selected object is assigned to variable x.
If the selected object is a rod object, the rod object id is assigned to variable r.
Each of the properties on the selected object are printed with the property name, property value and the cdf prompt if there is a cdf. This should tell you the name of the property you are looking for. For vias, it gets parameters from the viaHeader~>overrideParams.

I use Virtuoso 6, not ICADV 12, but I think it should still work. Just select your via and run this command:

procedure(mysel()
  let((promptTable)
    x=car(geGetSelectedSet())
    promptTable = makeTable("cdfPrompts" nil)
    when(x~>objType=="inst"
        cdf = cdfGetInstCDF(x)
        foreach(p cdf~>parameters
            promptTable[p~>name] = p~>prompt
        )
    )
    printf("x = %L (%L)\n" x x~>objType)
    r=rodGetObj(x)
    printf("r = %L\n" r)
    if(x~>prop || x~>viaHeader~>overrideParams then
        printf(" \nProperties on selected object:\n")
        printf("CDF Prompt Property Name (type) Value\n")
        printf("============================================================\n")
        foreach(prop x~>prop
            printf("%-25s = %-25s: %L\n" promptTable[prop~>name]||"no cdf" sprintf(nil "%s (%s)" prop~>name prop~>valueType) prop~>value)
        )
        when(x~>objType=="customVia" || x~>objType=="stdVia"
            printf("%s\n" x~>objType)
            foreach(prop x~>viaHeader~>overrideParams
                printf("%-25s = %-25s: %L\n" promptTable[car(prop)]||"no cdf" sprintf(nil "%s" car(prop) ) cadr(prop))
            )
        )
    else
        printf("No properties on selected object\n")
    )
    t
  )
)

Hi Boomme,

I think that you want to look at these functions: 

dbSetViaLayer1Control( 
d_viaId
t_colorControl
 )


dbSetViaLayer2Control( 
d_viaId
t_colorControl
 )

The colorControl argument has values like noColor, noShift, shift1 and so on. There is also a dbSetViaLayerControl() function and a dbGetViaLayerControl() function.

The above should allow you to code something to change the via metal colors (the cut layer can be controlled by dbSetViaCutLayerControl() )

Best regards,

Lawrence.

Thanks guys for the replies...Since my previous post, I actually had just located and figured out on my own the dbSetViaLayer2Contol functions... and already implemented it (works great). And I copied and tried your code dmay - it seems to print out a lot of great info for cells/cells - but when i tried it for the vias or shapes it errors out to the "no properties on selected object" message. I know there still has to be a way to list/find out the attribute parameters variable field names for objects, shapes, cells, etc. - I've wished I had that info a thousand times over the past years. Thanks again for replying everyone.

For an object in the database, you can simply type obj~>? to find the attribute names and obj~>?? to find the names and values. So for example:

car(geGetSelSet())~>?

will find the attribute names of the first selected object. This doesn't help you when the thing you need to set has to be done via an API - not everything is available via an attribute.

Regards,

Andrew.
