• Folder structure:

  • test_cases/
    • input/
      • input waveforms, generated by MATLAB, including:
        • Sine Waves with 50, 49, 51, 5, 200 kHz, with phase angles: 0°, 30°, 45°, 90°, 120°
        • Rectangular Waves with 50, 16, 10, 200 kHz, with phase angles: 0°, 30°, 45°, 90°, 120°
        • Triangle wave, 50 kHz, with 0° and 90° phase angle
    • expected/
      • expected results of the corrosponding waveforms, generated by MATLAB
    • file format: 1 sample per line, in HEX
  • goertzel_testcases.m
    • simulation using MATLAB
  • goertzel.vhd
    • Goertzel algorithm implemented in VHDL
  • goertzel_tb.vhd
    • test bench for goertzel.vhd, using the test cases in test_cases/

• Naming convention in VHDL:

  • Hungarian notation, as mentioned in the lecture slides

  • use capital letters for the first letter of the signal name

  • use all capital letters for constants

  • suffix:

    • I/O/B at the end of the suffix, indicating the direction of the signal

      • I for input
      • O for output
      • B for bidirectional

    • S/C at the beginning of the suffix, indicating the type of the signal

      • S for signal
      • C for clock

    • e.g. Ena_SI, Rst_RBI, Clk_CI

    • _D if internal signal

  • Reset: Rst_CI

  • Clock: Clk_RBI
