Trying to connect the PG aroung the block to the ring (sroute blockpins).
As seen the attachment the sroute, routes only gnd on the top and vdd on the sides. And leaves vdd on top and gnd on sides open.
sroute does not leave any warnings or errors.
Thanks for your replies..
Sorry just found the reason.
the space inbetween ring and the block is small enough to insert the vias.
But I think there should be an option to choose the via size in this case. ... Encounter uses a default sizes.
