I am building in layout decoder9->512 , is where any way to copy the pin
names out<0> ,out<1>... out<511> automatically without writing each
name?

I wrote a pcell to do this for me. It generates a set of shape pins on a
given layer (you'll have to change this in the code yourself) with a
given name and spacing. You can add it to your layout, flatten it whilst
preserving pins and then change the layer and direction according to
your needs.

Improvements, as ever, gratefully received.

In the "Create Pin" form you can enter out<0-511>, assign a x or y pitch and
Click to expand...
place them all with one click (if its a symbolic pin) or draw the shape for the
first pin and all others will be placed with the pitch.
Ofcourse that means you have to have all the shapes of your signals placed with
that pitch.

Sorry, ofcourse it has to be out<0:511>
 
It works only in the schematic composer.
I wish we had this feature in the layout editor too -- I will request a
PCR for this.

No, Marc is correct and made me look stupid :)

In my defense, I needed to pcell to do this anyway as I needed seperate
pin labels.

Did you actually test it? This is working since some years for the Layout too
when creating Pins.

It wasnt my intention to make you look stupid. ;)
What you mean with seperate pin labels? You can control the layer of the labels
independent from the pin layer from the same Create->Pin menu.

The design kit we use demands normal pins for diva but label "pins" for
Assura. Assura didn't recognise the labels attached to the diva pins
even if they were on the correct layer so I had to create the
seperately. Most vexing.

I did not test it properly. It works now :)

that's because they were not labels but 'text displays'.
