Why does auto routing on altium freeze ?

[bianchi77]

Guys,

I tried to do auto routing on altium but the software is freezing,
Anyone has a clue why ?

I only connect one net and create the edge connector by myself, is it because of my connector ?
Please see my screenshot attached,

Thanks

Hi,
Please check your Design Rules.

there can be situation like in schematic both are not properly connected so therefore can't be connected in layout also,
secondly auto router stops routing when it doesn't find any space to make a trace, since you are using a BGA, defined on top layer it is not finding a way to pass cross all other pads because it will short, nor it is finding any space to insert via and route on the bottom layer!!!
