Strange Issues in spiceIn

Hi, all

 I have a problem during spiceIn.  I want to import hspice to schematic, but I get an error of:

Inst: RXM0
Found net 'AIN'.
Found net 'AINOUT'.
Master Cell: 'resistor'.
Did not find 'silterraC13.resistor:symbol'.
ERROR (SPICEIN-24): Spice In did not find the symbol view of the master cell 'resistor' of the instance
'RXM0' in the subcircuit 'ANALOGIO60_33'. Specify the reference library that has the symbol
view of the master cell, or use device-mapping to map 'resistor' to a different

Actually, in the spice file, the model of RXM0 is not resistor but "sbpp". And sbpp does exist in the reference library.

.subckt ANALOGIO60_33 AIN AINOUT AVDD33 AVSS33 VDD VSS VSSIO VREF DIFREF
DXDM16 AVSS33 AIN pnt AREA=75.717P PJ=112.208528U
DXDM17 AIN AVDD33 pnt AREA=75.717P PJ=112.208528U
DXDM14 AINOUT AVDD33 pnt M=4 AREA=75.717P PJ=112.208528U
DXDM15 AVSS33 AINOUT pnt M=4 AREA=75.717P PJ=112.208528U
MM6 AVSS33 AVDD33 AVSS33 AVSS33 nm_33 W=324U L=8U M=1
RXM0 AIN AINOUT sbpp w=6U l=6U
.ends

 When I mapped "resistor" to "sbpp" in device mapping file, all the resistors in the spice file are mapped to sbpp. 

 The cadence version is IC6.1.5, any one knows how to fix this ?

Thank you!

    Dear Andrew,

      In the netlist, there are 2 different types of resistors: sbpp and snp. So the device mapping file I am using is:

     devSelect := resistor snp
            propMatch := subtype snp

     devSelect := resistor sbpp
            propMatch := subtype sbpp

    But  there are still problems after spicein.

    the resistor defination in netlist is :

     RXM2_I59_I1_I0 I1_I0_NET0126 I59_I1_I0_NET069 sbpp w=1U l=26U

    in spicein.log, 

     Inst: RXM2_I59_I1_I0
            Created net 'I1_I0_NET0126'.
            Created net 'I59_I1_I0_NET069'.

            Master Cell 'resistor' mapped to 'snp'.
            Did not find 'analogLib.snp:symbol'.
            Master Cellview: 'silterraC13.snp:symbol' found.
            Created instance 'RXM2_I59_I1_I0'.
            Created connection between net 'I1_I0_NET0126' and term 'PLUS'.
            Created connection between net 'I59_I1_I0_NET069' and term 'MINUS'.
            Created propName='model'; propType='string'; propVal='resistor'.
            Created propName='calculatedparam'; propType='string'; propVal='Length'.
            Created propName='r'; propType='string'; propVal='sbpp'.
            Created propName='segW'; propType='string'; propVal='1e-06'.
            Created propName='segL'; propType='string'; propVal='2.6e-05'.

     It seems that spicein didn't treat "sbpp" as a subtype, but the resistance value. So that only the first mapping commands "devSelect := resistor snp     propMatch := subtype snp " is effective, and all the "sbpp" and "snp"resistors are mapped to "snp",  also the resistance value is set to a string "sbpp" or "snp".   How to map correctly in tis case?

    Thank you!
