Is there a convenient way to specify the order of nets for each side in a power ring created by addRing in encounter? By default it keeps the order but I'd like the order along my top edge to be VSS, VDD while having VDD, VSS on the bottom edge. My starting point is:
addRing \
-around user_defined \
-user_defined_region [list $llx $lly $urx $lly $urx $ury $llx $ury] \
-width 1.0
-spacing 0.5 \
-offset 0.0 \
-layer {top M1 bottom M1 left M2 right M2} \
-nets [list {*}$myvdd {*}$myvss]
I have tried using "-skip_side top" and then adding addStrip to try and add the top of the right with swapped VDD/VSS but can't seem to figure out the right magic to get that to work.
Any tips? This seems like it shouldn't be that unusual.
Thanks
