The geometrical transformations are described according to that model.

<p>This table is to translate <em>default</em> VIAs into real via. In the symbolic layout

the default VIA is simply a point and a set of layers. All layers are converted

in squares shapes centered on the VIA coordinate. The one dimension given is the

size of the side of that square.</p>
|

<p>Note that although we are refering to VIAs, which for the purists are between two

metal layers, this table also describe <em>contacts</em>.</p>
