Could you please give the logic in verilog..

p_input is a pipeline, a shift register is used to delay the input signal “i_input”.
It is a simple trick the generate the delayed version of the signal, in this case 3 registers (0 to 2) and derive the rising and falling edge

What does it do in the circuit? Why did you define it as 3 bits? What happened in lines 35, 36 and 37 ?! Thank you for your reply

If you don’t need to synthesise the code, you can use VHDL like a programming language.
In this case you can find a lot of algorithm in literature

In my application, I need to measure the frequency and amplitude of an incoming sinusoidal signal (analog). And this has to be done in VHDL (not synthesisable, because this isn’t on FPGA but outside). Is it possible to do? If yes, then please could you help me with this?
Thanks in advance.
