[Xcircuit-dev] RE: XCircuit netlist to pcb problems

[Eric Y. C. <er...@al...>]

Hi Tim.  I used defaults for both runs.  I did remember 1/6 in.
The 2.3.3 did not work, but the 2.5.4 did.  It came up with the
correct netlist (having connectivity).  Note that the 2.5.4 did
not produce a picture in which the diode end points lined up
with each other (now clear from your explanation).  But, the
netlist extraction worked just fine, presumably due to the
tolerance for accepting a connection.

The 2.3.3 drew a picture that was less well aligned.  This 
could have been the root cause, or it could have been a
netlisting bug.

Anyway, I am now using 2.5.4 (which has incidentally had less
crashing problems than 2.3.3 as well).  It works just great for
the netlisting, aside from the asthetically displeasing diode
picture.  Should enforce a 45 degree prohibition :-).  Just
kidding.

Thanks for all the help.

Eric
