Greetings,
I have a design
where I need to connect nets of different names. While I've done this many
times, there's a hitch in this design. My boss is very uncomfortable with my
present method of combing nets because it take an interaction with the board
shop to make my intention clear. I create a different layer and I call it
ADD_ETCH and it is laid across the gap to connect two different nets. This does
not create a DRC in the layout but when implemented at the board facility it
will create a DRC. Of course, when the board is in CAM, I will get a phone call
(every time) to confirm my intent. I now have to come up with a method to have
the connection show up when viewed with an external Gerber
tool.
The way I intend
to approach this is wait until the design is almost near completion and change
both nets to STATIC SOLID vice DYNAMIC SHAPE. I will then drop a polygon of
appropriate dimensions across the gap(layers of concern are internal). I am
presuming this will cause a DRC. My questions are:
1) Is this method
reliable?
2) Changing from one
shape type to another will not change the attributes of either shape, correct?
For example, if I have a net named GND and the other is GND_PWR, the layers that
these net names are assigned to retain their original names,
correct?
This exercise is to
be able to see a physical connection when viewed by a typical gerb tool. Any
advice or clarification will be greatly appreciated. Referrals to specific
literature would be useful also. Thanks.
Cheers,
