Hello,
I am planning to write a verilog-A code for a 4 bit serial in parallel out shift register. But I am getting an error. Any idea about this ?
Here is my code..
And this is the error...
I am planning to write a verilog-A code for a 4 bit serial in parallel out shift register. But I am getting an error. Any idea about this ?
Here is my code..
Code:
`include "constants.vams"
`include "disciplines.vams"
module SIPO_4(din, clk, reset, dout0,dout1,dout2,dout3);
output dout0,dout1,dout2,dout3 ;
input din ;
integer din ;
input clk ;
electrical clk ;
input reset ;
electrical reset ;
parameter real vtrans = 0.5;
integer temp[3:0];
analog begin
@ ( cross ( V(clk) - vtrans, +1)) begin
if (V(reset) == 1) begin
temp[3] <= 0;
temp[2] <= 0;
temp[1] <= 0;
temp[0] <= 0;
end
else begin
temp[3] <= din;
temp[2] <= temp[3];
temp[1] <= temp[2];
temp[0] <= temp[1];
end
dout3 <= temp[3];
dout2 <= temp[2];
dout1 <= temp[1];
dout0 <= temp[0];
endmoduleAnd this is the error...
