Thanks for the reply crossrulz and congrats..
If i use a greater than condition,when the sine wave goes positive ,it would give true value.But when the sine wave again becomes negative,the if condition gives a false.My requirement is when the sine wave goes positive,i should able to generate a square wave continously regardless of the sine wave condition.However,i did this part using an SR latch and a switch.I have attached the block diagram.But the problem now is,when the square wave starts to give output,the sine wave appears like a stepped function.I have attached that picture as well.Cant,both the generators simultaneously generate waveforms?Is there some changes i have to do with FPGA Clock?
