Decoder Cadence ADE Simulation problem

Decoder Cadence ADE Simulation problem(I did not see this error never before))

Hello Experts,

I was designing a 2x4 decoder for my use in the implementation of FPGA CLB. when i try to simulate the decoder circuit using the cadence ADE i am getting errors as below.

WARNING (OSSHNL-117): Ignoring switch view 'schematic' of cell 'gnd' in library 'basic', as it does not contain
any instance. To netlist this cell, add this switch view to the stop list or to
ignore any specific instance set the property 'nlAction' to value "ignore" on
this cell view.

WARNING (OSSHNL-117): Ignoring switch view 'schematic' of cell 'vdd' in library 'basic', as it does not contain
any instance. To netlist this cell, add this switch view to the stop list or to
ignore any specific instance set the property 'nlAction' to value "ignore" on
this cell view.

WARNING (OSSHNL-160): The primitive, 'NCSU_Analog_Parts/vdc/spectre', was not used in the last netlisting session in this
current run directory. Therefore, re-netlisting all cell views where this
primitive is instantiated.

Netlist Warning: The netlisting procedure specified for (NCSU_Digital_Parts nfet spectre) is
obsolete. You can convert your library with the
Tools - Conversion Tool Box menu on the CIW.

*Error* ilGetString: arg must be symbol or string - progn(bn)
*Error* ilGetString: arg must be symbol or string - progn(bn)

I am attaching my schematic and the circuit(created by importing the symbol and adding the voltage sources) i used for the simulation.

Please help me. iam stuck

You want to either use the Hierarchy editor and assert
the proper / intended stop-view (probably "spectre") or
look at the views list that ADE has (one of the simulator
options pulldowns, I forget which). You'll see lists that
go like "schematic cmos.sch symbol spectre". Look at
what views actually exist under your basic/gnd symbol
and make sure its -appropriate- stop-view shows up in
the stop list, and that schematic does not (you can't
do anything useful, stopping at a schematic view and
failing to netlist anything lower). schematic needs to be
in the switch view list and absent from the stop view list.
Same goes for cmos.sch and cmos_sch.
