Max10 propagation delay and frequency error

In a Max10 10M02SCE144I7G I have a variable frequency input signal from 0Hz to about 80kHz. On that signal I apply a digital filter to remove the glitches (without changing the frequency with a gloa...

Hi,

If you have connected the input to output without any logical operations, You have to see the same signal with the same frequency.

  1. How are you are comparing the signals using Oscilloscope and probing on hardware right?
  2. Which pin in hardware are you checking/probing?

If you are seeing different signals.

  1. You are checking at the wrong place on the hardware/PCB board.
  2. The output of FPGA is passing through passive or active components.
