Hello,I have written code for s27 benchmark circuit and counter,I have given output of counter to s27 circuit.When I run the view RTL schematic its showing following error:
ERROR:Xst:528 - Multi-source in Unit <s27test2> on signal <out<3>>; this signal is connected to multiple drivers.
Drivers are:
Primary input port <G3>
Output signal of FDR instance <str1/d_3>
how to resolve this?
I have used instantiation.Below is the code

Code:
module s27test2(G1,G2,G3,G0,clock,reset,out,G17);
input clock,reset,G1,G2,G3,G0;
output [3:0]out;
output G17;
counter str1 (.clk(clock),.rst(reset),.d(out));
assign G0=out[0];
assign G1=out[1];
assign G2=out[2];
assign G3=out[3];
s27 str2(.CK(clock),.g0(G0),.g1(G1),.g2(G2),.g3(G3),.g17(G17));
endmodule
