Introduction Test Procedure

Introduction

This document describes a number of tests that can be performed to verify that the design works as it should.

Within each test procedure, the tests are denoted as bullet-points, followed by some text describing what to do. Results are denoted as "-> something", where something is the expected result.

A description of the hardware is shown below: alt tag The above image shows:

  • Nexys4DDR development board,
  • VGA port connected to a vga monitor capable of 800x600 @ 50Hz and 60Hz
  • USB port connected to a simple USB keyboard,
  • PROG/UART port connected to host-PC, for two reasons:
  • to provide power to the Nexys board, and
  • to allow serial comms between Nexys and host-PC. The host-PC should have the m65dbg running or a suitable serial-port program. I use picocom.
  • SDMICRO port has a SDcard inserted, SDcard should contain the following files at a minimum:
  • bit03141732_dev..._1541f08~.bit (or similar) BOOTLOGO.M65 (optional) CHARROM.M65 MEGA65.D81 MEGA65.ROM
  • FPGA-Switches (SW-x) all in their OFF position, which is DOWN, if using a Nexys4 or Nexys4DDR development board.

Test Procedure

All tests, unless otherwise noted, begin with the hardware as described above in the "Introduction" section above.

For the individual tests, please see below.

  • Power and BOOT-up - applies power and describes what should happen when the buttons/switches are manipulated.
  • c65 mode - navigates around the c65 environment exploring its features.

The End.
