Differentiate drcs: Symbol Vs Design

SambaKantipudi

Hello All,

I have symbols in my library that were intentionally created to violate DRC rules.

After logic import, they are transferred to the layout editor, along with their DRCs.

The command axlDBGetDesign()->drcs gives me all the DRCs in the design.

Which SKILL commands or functions can differentiate between Symbol DRCs and Design DRCs?

Thank you very much in advance.

    Hi Samba,

    This is an interesting question. You can check this by looking at the 2 entities generating the error. There is a DRC_ID->violations property that returns the list of figures causing error. By looking at their entity_id->parent and up you can figure out if they are coming from the same symbol or not.

    However, please note that in layout, you can attach a property to the Symbol (via Edit-> Object Properties), named Nodrc_Sym_Same_Pin = True that helps you get rid of these errors for good. This assumes you know very well what library is doing.

    Hello  

    violations~>parent~>type

    violations~>parent~>objType

    I tried the same, but was unsuccessful.

    For an example:

    Shape to Shape drc error, part of symbol was shown as design drc.

    Doesnt know how to proceed further!!

    Thanks

    Try the code below, it should give you a starting point. I am sorry, parent indeed didn't set you in the right direction.

    ; the code below works in my case for a pin to pin DRC. You might adjust your code a bit to cover all scenarios
    axlSetFindFilter(?enabled `("NOALL" "DRCS") ?onButtons `("DRCS"))
    ; after entering next line, you must click on an error to move on
    mySymbol = car(axlGetSelSet(axlSingleSelectPoint()))
    parentList = mySymbol->violations
    first = car(parentList)
    myComponent = first->component
    mySymbol = myComponent->symbol
    myRefDes = mySymbol->refdes
    axlClearSelSet()

    the output, after entering this line by line is shown below, as you can see, it shows the RefDes at the end.:

    note: last lines can be optimiezed into this:

    myRefDes = first->component->symbol->refdes
