只里是我写的veriloga的代码
// VerilogA for ADV7180_CLAMP, CLAMP_demo, veriloga
`include "constants.vams"
`include "disciplines.vams"
module CLAMP_demo(clamp_ctrl,SIGNAL,DC_OUT,AC_OUT,SEL_HL,LEVEL_H,LEVEL_L);
input SIGNAL,SEL_HL,clamp_ctrl,LEVEL_H,LEVEL_L;
electrical SIGNAL,SEL_HL,clamp_ctrl,LEVEL_H,LEVEL_L;
output DC_OUT,AC_OUT;
electrical DC_OUT,AC_OUT;
real X,Y,Z;
analog begin
@(initial_step) begin
Z=0;
end
@(cross(V(clamp_ctrl)-1.7,+1)) begin
if (V(SEL_HL)>1.7)
begin
Y=1*(V(LEVEL_H)-V(SIGNAL));
X=V(LEVEL_H);
end
else
begin
Y=1*(V(LEVEL_L)-V(SIGNAL));
X=V(LEVEL_L);
end
Z=Z+Y;
end
V(AC_OUT)<+V(SIGNAL)+Y;
V(DC_OUT)<+X;
end
endmodule
