db command to get power pin co-ordinates for a given Macro

deeps

 Hi,

    I am trying to get the power pin co-ordinate details for a given Macro, 

        Is there a way by using db commands we can get the exact co-ordinate details of the power pins that are present on the Macro.I am using dbGet command to get the co-ordinate details of the macro location.

 

thanks

    Thanks JG,

    That's the way I'd do it too.  One additional command to be aware of is "dbTransform" that performs the translation you're referring to which converts the cell-level coords to chip-level.

    For example, if you have a cell that's instantated at 0, 884.82 with R270 orientation, you can translate each of the pgTerm rects to chip coordinates like this:

    encounter 26> dbGet selected.pt
    {0 884.82}
    encounter 27> dbGet selected.orient
    R270

    encounter 28>dbGet selected.cell.pgTerms.pins.allShapes.shapes.rect                                                                             
    {5.355 226.625 34.645 235} {5.355 226.625 34.645 235} {5.355 226.625 34.645 235} {5.355 226.625 34.645 235} {5.355 207.72 34.645 235} {5.355 207.72 34.645 235}

    encounter 29> foreach rect [dbGet selected.cell.pgTerms.pins.allShapes.shapes.rect] {puts "[dbTransform -localPt $rect -inst [dbGet selected]]"}
    {226.625 919.465} {235 890.175}
    {226.625 919.465} {235 890.175}
    {226.625 919.465} {235 890.175}
    {226.625 919.465} {235 890.175}
    {207.72 919.465} {235 890.175}
    {207.72 919.465} {235 890.175}

    Hope this helps,
