Reply To: Pin attributes

[alvin]

Assuming I have defined cellA and it has the pin ‘lb’ which is set to be at the bottom left corner of the cell. I want to put a space in y-direction of 50 um between cellA and the sequent cell (cellB) automatically without knowing the actual size of cellA.
I found if I do this:

nd.cp.goto_pin(cellA.pin['lb'])
nd.cp.move(0,-50,0)
cellB.put()

It returns an error:

Exception: Not allowed to create a node outside the scope of max one level deep.

associated with the use of

nd.cp.move(0,-50,0)

after using

nd.cp.goto_pin

However, there is no error if I do this:

nd.cp.goto_pin(cellA.pin['lb'])
xya = nd.cp.here()
nd.cp.goto(xya.x,xya.y)
nd.cp.move(0,-50,0)
cellB.put()

It is a little bit troublesome!! Is there any way I can use

nd.cp.move(0,-50,0)

right away?
