I am trying to run the LVS of a mixed-signal system and for some blocks I want to use the LVS BOX statement to skip them during LVS.
For most of the cells this works correctly but for two of them I am having a "Layout extra pin" issue. I have checekd the netlist generated by Calibre from the layout and these pins are actually there but if I look for them in the layout, they do not exist. These extra pins always have a numerical name such as "27", "30" or "89".
Do you know what could be happening?
Thanks in advance.
