Hi
Here verilogA code for transformer
// VerilogA for edaboard, transformer, veriloga
`include "constants.vams"
`include "disciplines.vams"
module transformer(pr1,pr2,sec1,sec2);
inout pr1,pr2,sec1,sec2;
electrical pr1,pr2,sec1,sec2;
parameter real n1 = 1.0 from [1:inf); //number of turns in primary winding
parameter real n2 = 3.0 from [1:inf); //number of turns in secondary winding
parameter real L = 1n from (0:inf); //inductance per one turn in H
parameter real k = 0.97 from [0:1]; //mutual coupling factor
parameter real R1 = 1.0 from [0:inf); //resistance of primary winding in Ohm
parameter real R2 = 3.0 from [0:inf); //resistance of secondary winding in Ohm
real F1,F2;
analog begin
F1 = L*(n1*I(pr1,pr2)-k*n2*I(sec1,sec2)); //magnetic flow through primary winding
F2 = L*(n2*I(sec1,sec2)-k*n1*I(pr1,pr2)); //magnetic flow through secondary winding
V(pr1,pr2)<+R1*I(pr1,pr2)+n1*ddt(F1);
V(sec1,sec2)<+R2*I(sec1,sec2)+n2*ddt(F2);
end
endmodule
Appreciate any suggestions about improving it.
Regards.
