Hi!
currently I tried use A foundry ported to B foundry,
and find abnormal from Fluid Guard Ring issue,
this Fluid Guard Ring just can't show the NPLUS layer
I'm sure I recreate A and B foundry Fluid Guard Ring procedure(sorry I needed mark the foundry pdk name),
is the foundry PDK cause or the my porting script mismatch?
or my create Fluid Guard Ring in CIW Technology File Manager procedure wrongs?
should I change any action?
the pic in layout ported from A to B foundry like this show pcell Eval Failed
and zoom in like this, I know just the NPLUS can't thru the porting script(other layer ported and correct).
warning message as below
I thought the layer lock before layer name data.
(in A foundry is "SN" layer, B foundry is "NPLUS" layer)
but another layer ported correct,
I'm confuse if my set wrong, should be all layer abnormal,
but just "SN" layer ported failed,
thanks tour reply!
Best Regards.
