Finding the primitive polynomial of an LFSR

The aim of this task is to find the primitive polynomial of an LFSR whose sequence is displayed on LEDs.

Specifications

An FPGA generates a 4 bit LFSR at the rate of 1 Hz. The 4 bits are displayed on 4 LEDs on the buttons and LEDs board.

The primitive polynomial of the LFSR is to be found.
