Not that I want to use global power node (i.e., vdd! and gnd!), but the digital core library from the foundary already vdd! gnd gnd! defined in its layout.
That's why I am having a problem....any suggestion??? Even without any physical wire connection between gnd! (since it has been used in digital library, I used gnd! for my digital part) and AVSS (my analog vss), Calibre LVS check recognize them as connected!
Even in hierarchy structure, for example, I envoke the inverter (from foundary) without assigning any pin on gnd! port, Calibre LVS check recognize that layer as gnd!. What should I do?
Best,
