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 ?
