Until I add netclass support, probably sometime next year, your best
option is to export to DSN from PCBNEW and then manually edit the DSN
file and create your own netclasses in the DSN file using a text
editor. This is cumbersome the first time, but it is worth the
effort. I do this once, then save off the portion of text that needs
to be pasted in, so that I can paste it in again on another, future
round trip to freerouter.
You may need a copy of the DSN specification to fully understand the
format.
Here is a sample of what I paste into the end of the network scope, i.e. :
(network <existing stuff> <paste here> )
Here is a sample paste fragment that creates a new netclass called
"powers". It tells freerouter that all power traces should be wider,
i.e. 16 mils, with clearance of 4 mils, and with a via 18 mils wide
with a hole of 12 mils wide. (Note that this is simply a reference to
a via that was already used elsewhere, you cannot define a NEW via
here.) The default netclass uses a trace width of 4 mils in this
board, so this netclass definition creates a group of exceptions to
that default:
Paste sample:
(class powers GND V3.3 V3.3D V3.3A V1.8 V1.8A
COMMON V5.0 EGND VCCPOE VCC_FT
N-000477 N-000479
(circuit (use_via Via[0-5]_18:12_mil))
(rule (width 16)(clearance 4))
)
Hope this helps,
Dick
