    Leela,

    Is this in a schematic, a symbol, or a layout (where probably you'd want 10 individual pins)?

    In general you'd do:

    net=dbMakeNet(cvId "pinname<1:10>")
    pinMaster=dbOpenCellViewByType("basic" "ipin" "symbol")
    pinFig=dbCreateInst(cvId pinMaster "" 0:0 "R0")
    pin=dbCreatePin(net pinFig)

    Or you could use:

    pinMaster=dbOpenCellViewByType("basic" "ipin" "symbol")
    schCreatePin(cvId pinMaster "pinname<1:10" "input" nil 0:0 "R0")

    Something like that.

    Andrew.

    Obviously you'll need to create separate pins for each bit, so you'd do something like:

    pinWidth=0.5
    pinPitch=1.2:0
    pinOrigin=0:0
    pinLayer="Metal1"
    pinDirection="input"
    busPin="pinname<1:10>"
    foreach(pinName dbProduceMemName(busPin)
      ; create the pin shape, then the net (if it doesn't already exist), and then create the pin
      pinFig=dbCreateRect(cvId pinLayer list(pinOrigin xCoord(pinOrigin)+pinWidth:yCoord(pinOrigin)+pinWidth))
      net=dbMakeNet(cvId pinName)
      pin=dbCreatePin(net pinFig)
      ; make sure the terminal direction is what we want too
      pin~>term~>direction=pinDirection
      pinOrigin=xCoord(pinOrigin)+xCoord(pinPitch):yCoord(pinOrigin)+yCoord(pinPitch)
    )

    Regards,

    Andrew.

     Thank you, I used "dbProduceMemName()" in foreach loop to get each pin bit and then created a pin.  Its working good.
