OSS netlisting inherited gnd problem

Dear all,

we are having a strange issue when netlising our design with the OSS netlister (via runams command-line).

Some of the inherited grounds nets are being strangely netliested. For instance, an inherited net that should be netlisted as \vss! ; is being netlisted as \vss_vss! ;  that is, its name is being duplicated. This causes elaboration errors.

Here's what we see: 

 // Verilog-AMS netlist generated by the AMS netlister, version 5.10.41.500.6.149.

// Cadence Design Systems, Inc.

(* cds_ams_schematic *)

module and2_2 ( x,a,b );

 output   x;  input   a;  input   b;

 wire (* 

integer inh_conn_prop_name ="vdd";

integer inh_conn_def_value

= "cds_globals.\\vdd!";

*)

\vdd! ;

wire (*

integer inh_conn_prop_name ="vss";

integer inh_conn_def_value

= "cds_globals.\\vss!";

*)

\vss! ; 

  \nmos  #(.ad(( max(1.120 , 0.7) * 0.805 )), .nrd(( 0.28 / 1.120 )), .vds("2.5"),

.pd(( 2.0 * ( max(1.120 , 0.7) + 0.805 ) )), .w(1.120), .lpe(0), .as(( max(1.120 , 0.7) * 0.805 )),

.nrs(( 0.28 / 1.120 )), .np(1), .ps(( 2.0 * ( max(1.120 , 0.7) + 0.805 ) )),

.l(0.28)) (*

integer library_binding ="smos8mv_ams";

*)

N53 ( x,

nnet6, \vss! , \vss!  );

\nmos  #(.ad(( max(0.630 , 0.7) * 0.805 )), .nrd(( 0.28 / 0.630 )), .vds("2.5"),

.pd(( 2.0 * ( max(0.630 , 0.7) + 0.805 ) )), .w(0.630), .lpe(0), .as(( max(0.630 , 0.7) * 0.805 )),

.nrs(( 0.28 / 0.630 )), .np(1), .ps(( 2.0 * ( max(0.630 , 0.7) + 0.805 ) )),

.l(0.28)) (*

------------------------------------

using runams (OSS NETLISTER),FOR THE SAME “AND2_2”, I got a different format netlist, which gave ncelab errors.

2)     ---------------------

module and2_2 (x, a, b);

output  x;

input  a, b;

wire (*

integer inh_conn_prop_name ="vdd";

integer inh_conn_def_value ="cds_globals.\\vdd! ";*)

cdsNet1;

wire (*

integer inh_conn_prop_name ="vss";

integer inh_conn_def_value ="cds_globals.\\vss! ";*)

cdsNet0;

wire (*

integer inh_conn_prop_name ="vss";

integer inh_conn_def_value ="cds_globals.\\vss! ";

*)

\vss_vss! ;

\nmos #(.l(0.28), .w(1.120), .as("(max((1.120),0.7)*0.805)"),

    .ps("(2.0*(max((1.120),0.7)+0.805))"),

    .ad("(max((1.120),0.7)*0.805)"),

    .pd("(2.0*(max((1.120),0.7)+0.805))"), .nrd("(0.28/(1.120))"),

    .nrs("(0.28/(1.120))"), .lpe(0), .np(1), .vds(2.5)) N53 (x, nnet6

    , cdsNet0, \vss_vss! );

So the cdsNet1, cdsNet0, \vss_vss! Are all the ncelab errors.

Any ideas? 

thanks for your support.
