I created this pad, inside pad is signal pad, outside is GND,
the net wiring is okay
but when i do routing of inside signal pin, it displayed : E-[SPMHAC-20]Unsuccessful route:cannot find a path through the obstacles.
if the outside circle closed, then no this problem , i can use via for routing signal pin . But we don't want to use via for high speed.
Who can help me ?
The error is telling you that the route width does not meet the DRC rules while routing. Turn off DRC while routing in the OPTIONS tab and route. Be sure to solve the problem with clearances before completing the board.
In reply to redwire:
I open more bigger window, it's okay for general signal, but after I set this signal to be DP pair, then have another problem , it cannot be connected to the other net with the same symbol. Strange
It made me crazy for this symbol.
In reply to newstyle:
Can you post a board file with the problem? There is a solution but it is difficult to solve directly on the forum.
Thanks, the problem solved.
I changed to routing from outside to thie pin, then it's okay. Every strange.
The forum is very good, i started from scrtch, but learned much. Thanks,
