hi folks
how r u all. hey i'm facing a problem as usual. pleas check a simple program which is given below
module led(HEX,LED);
input HEX;
output LED;
reg LED;
always @(HEX)
begin
case (HEX)
1'b0 : LED = 1'b1; //1
1'b1 : LED = 1'b0; //2
default : LED = 1'b0; //0
endcase
end
this program was compliled and synthesised using ISE 5.2/ this program compiles and synthesise without any error or warning. now here comes the problem when i give the constraints for pins for this file it successfully genrates the bit file as well as sucessfully the mcs file is genrated. when the mcs file is loaded to the fpga prom it doesnot executes. can anybody tell me y this is happeneing. what could be the error over here. what is the possible solution. i'm using spatranIIE XC2S300E fpga on the board supplied by MEMEC.
thanx in advance.
