Vector net cannot be connected to a Spice/Spectre instance by port name.

Hi, I am running an AMS-spectre simulation and I have an issue during post-layout simulation. I have a subcircuit which includes vector as the input. However, when I use the dspf file(post layout netlist), I receive an error in not detecting the vector. I have checked the pins orders in post-layout netlist and is fine. ( I don't have this error for normal netlist even where the vectors are defined) I wonder how I can solve this issue? Is there an issue for instance of defining vectors? bit or bit[1]? Below is the error I receive. ncsim: *E,SYERROR (~/mmsim.38/1/mmsim/netlist/netlist.vams,61|32): Vector net cannot be connected to a Spice/Spectre instance by port name. adc_ana Iadc_ana0(.thermo( thermo[62:0] ), .comp_in( comp_in_int ), .vin( cap_in ), .bin( bin[5:0] ), .insw_en( insw_en_int ), .insw_en_n( insw_en_n_int ), .ref_en( ref_en_int )) BR, Nami
