Why this is happing ? i have no idea
Cell analog in netlist has not been loaded.
This is the spice netlist i want to be loaded for port matching in magic.

@Partha Singha Roy what does the cell contain?

@Partha Singha Roy: You have a mismatch between your layout, which is called
ANALOG_0
, and the netlist, which is called
analog
. Upper/lowercase is probably not important, but the
_0
is.
