Finding pin locations

archive

Hi, I use this to find an instance location: set instPtr [dbGetInstByName $instName] set loc [dbInstBox $instPtr] set llx [dbDBUToMicrons [lindex $loc 0]] set lly [dbDBUToMicrons [lindex $loc 1]] set urx [dbDBUToMicrons [lindex $loc 2]] set ury [dbDBUToMicrons [lindex $loc 3]] But, How do I find a pin location? Thanks Chris

  • Hi Chris,

    You can use:

    dbForEachCellFterm

    To go through each cell pin.

    You can then pass each ftermPtr from dbForEachCellFterm to:

    dbFtermLoc

    To get the pin location.

    set pinLoc [dbFtermLoc $ftermPtr]

    Then lindex into pinLoc:

    set x_loc [lindex $pinLoc 0]
    set y_loc [lindex $pinLoc 1]

    You'll also want to convert from db units to microns like you did in your cell example.

    Good luck!
