if we open a PCB file that doesn't specify an annulus min width then
the annulus min width should be set to the min width of the copper
lines.
I like the idea of expanding the vendor files to provide for the DRC
and drill mappings, making it a file that has the parameters seems
like a goo

Guys,
In Settings -> Sizes
-I have min annulus ring set to 5mil.
-Minimum copper width is set to 8mil.
My vias have a 10mil drill, 21mil outer
diameter. This should yield a 5.5mil
annular radius on the vias.
When doing DRC, it complains with:
"Via annular ring is too smal

I'm feeling dense today...a PC parallel port wire's fastest speed
is ~2.7MHz with no wait state mode, so you couldn't operate
at full speed talking to a SPI bus of a microcontroller...

I came across this in a trade magazine, Chip Design, and copy excerpts
that suggest what the "best of breed" tools can do. The author sees the
collection of abilities
as most valuable, and it seems not to be a copyright conflict to use a similar
collection of features,
just common sense.

Dear all,
Hi John,
Larry got my idea, he interprets it correctly.
Hi Larry,
Thank you very much for your answer, actually before starting the prototype,
i have the idea of using drivers source code, but i think about the
following scenario, if the hardware designer want to simulate his hardware
