Anyway, I'm not wire wrapping boards. I'm making PCBs and I almost always have mixed analog/digital on the same board. I prefer to keep the digital grunge out of my analog area. Sure, the auto router might like to find a path for a data pin right next to an op-amp input, but *I* don't want it there. I want to keep the data bus in a tight area, I'm not worried about crosstalk from data pin to data pin because the lines are settled by the time a chip select comes along.

He said it was a big cross talk problem. He wanted point-to-point with just a little slack in the wire length. Looks like some things never change. Tom Absolutely, I learned this from my WW days also. If you wanted the WW card to work with the least amount of noise, you never ran neat bundles Mike * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
