hi
I have written this code in vivado and I'm using kintex 7 fpga.
I receive this errors:
what should I do?
thanks.
I have written this code in vivado and I'm using kintex 7 fpga.
Code:
module top(
input sys_clk, //(* io_buffer_type = "NONE" *)
output tx,
input rx
);
//(* IOB = "true" *)
(* IOB = "false" *) reg [51:0] count = 0;
(* IOB = "false" *) reg reset = 0;
design_1_wrapper microBlaze(.clk(sys_clk),.rst(reset),.uart_rtl_rxd(rx),.uart_rtl_txd(tx));
always @(posedge sys_clk)
begin
count <= count + 1 ;
if ( count > 52'h3 && count < 52'h00F )
begin
reset <= 0;
end
else
begin
reset <= 1 ;
end
end
endmodule
I receive this errors:
