Sir,
For the following code while operating "INIT" command,
error coming is "cannot perform flatten herarchy.
Please tell me what's the problem with the code?
VIS supports using both posedge and negedge in the same code or not?
*******************************************************momodule main(clk,load,add,sub);
input load,clk;
output add,sub;
wire load,clk;
reg loadl;
reg[3:0] add,sub;
initial begin add=0;sub=0;end
always@ (posedge clk)
begin
loadl=load;
end
always@ (posedge clk)
begin
if(loadl) begin add=5;sub=5;end
end
always@ (posedge clk)
begin
add=add+1;
sub=sub-1;
end
endmodule
Thanking you
Vanessa
