Verilog A model of TFET

Hi All,
I am using verilog A model ofTFET from Penn State University which is given below.

`include "constants.vams"
`include "disciplines.vams"
module NTFET(d,g,s);
inout d,g,s;
electrical g,d,s;
real Ids, Cgs, Cgd, Qs, Qd,Qg;
parameter real W=1; //Device width
analog begin
Ids=$table_model(V(d,s), (V(g,s)), "IdVg-NTFET_Lg20nm.tbl","1LL,1LL");
Cgd=$table_model(V(d,s), (V(g,s)), "CGD-NTFET_Lg20nm.tbl","1LL,1LL");
Cgs=$table_model(V(d,s), (V(g,s)), "CGS-NTFET_Lg20nm.tbl","1LL,1LL");
if(analysis("dc")) begin
 I(d,s) <+ 1*Ids*W;
end
else begin
 
if(analysis("tran")) begin
 Qd = (-1*W*Cgd)*(V(g,d));
 Qs = (-1*W*Cgs)*(V(g,s));
 Qg=-1*(Qd+Qs);
 I(d,s) <+ 1*Ids*W ;
 I(d) <+ ddt(Qd);
 I(s) <+ ddt(Qs);
 I(g)<+ ddt(Qg);
 end 
end
end
endmodule

If anybody could help me in ac analysis from this model , I ll be thankful to him/her.

Thanks
