Hi, I had something very similar a few years ago, and it was caused by a circular board outline, which the autorouter doesn't like. Have you got any arcs in your board outline?

The router happily goes through the SMD fanout, memory & pattern routers but part way through the push 'n' shove pass it does a DRC and exits. No status report, no error message, no crash - it just stops. I've double checked that the board is within system capabilities, corrected a few off-grid components and even re-fanned out four 1152-pin BGAs to make sure the vias are all on-grid. There are still off-grid pads, but that sort of thing hasn't stopped the router on previous designs. The router seems to be objecting to something, albeit in a slightly more restrained manner than usual, but the question is what? Any hints/tips/solutions gratefully received. (BTW, the Protel version is P99SE/SP6 and the PC is an 800-and-something MHz P3 with 512M SDRAM running Windows 2000 Professional) Regards, Andy Gulliver ************************************************************************ * Tracking #: 0D6407EFA3F3654C90CDEC4D07962F5AD27F0FD9 * ************************************************************************ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 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/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
