Is there a way to set a component type to component type rule? What I =
mean is that certain component types tend to have different rules... =
such as 0402 to 0402 verses 0402 to SOT or BGA.
The only rules I have found are pad to pad... which does not allow for =
different type rules.
I spoke to some other designers and they offered two solutions: One is =
to build visual indicators into the parts so you can tell if your 0402 =
is too close to another 0402 or BGA... great, no DRC there. The other =
solution is simply use grids and place them... again no DRC.
I have different customers that require different spacings. One =
customer wants 20 mils between 0402 pads, another wants 25. Customer 1 =
wants 50 mils between BGA and 0402, customer 2 wants 40 mils between BGA =
and any other comp. =20
With other tools I had the ability to assign components to a component =
type and then assign rules of type to type. I don't see a way to do =
that in Allegro (15.1) (very similar to net type rules in Allegro, for =
component to component spacing)
What do you do?
