Hey Dan,
Have you tried using Allegro's 'Setup>Unused Pad Suppression' before generating
the ODB++ data?
the translator's "Unconnected Pads" optional parameters are disabled, since the
unused pads are already removed...

Hi Daniel
I think it is a bug cause by the offset...
The only pads to which it works are the pads where the c-line passes through
the middle of the oblong. (and not the drill)

Hi everybody
I have a situation where on inner layers some pads are being suppressed and
others are not. My intention is to have only the un-used pads suppressed.
In the picture, route.jpg, you will see the routing on an inner layer. In the
second row, there is routing going to three separate pads of the same
component. Notice how each route enters the pads.
In the pictures, pad-def1.jpg and pad-def2.jpg, it shows how the padstack is
defined. The option "Allow suppression of unconnected internal pads" is checked
on. The same offset for this padstack is used on all layers.
The picture, outpout-param.jpg, shows the parameters used when creating the
ODB++ output. The option "Suppress Unconnected Pads" is checked on.
The picture, results.jpg, shows the results in Valor. The padstack in the
middle is shown with its routing, but the padstacks on the ends are not shown
with their routing. It only seems to translate if the routing is coming from
below. I have changed the routing on the end pads to verify this.
This situation occurs using rel 16.2 and rel 16.3. We are still using
Valor/Enterprise release v8.21 bit still occurs with its latest translator.
Any ideas? I hope all the pictures come through so that you can see the
situation.
Thank you
Daniel
