Suggestion for how to test the minimig:

Sequence:
Jumper 2-3 (MCU TxD)
MCU(PIC18) verify it's own operation and sends result too TxD (builtin?)
Checks: 20 MHz clock, Flash interface, Rs232(rxd,rts,cts), FPGA jtag
Upload test config-1 to FPGA.
Check FPGA selftest is ok.
Upload test config-2 to FPGA.
FPGA
Check RAM with patterns.
Check CPU with opcode run.
Send picture pattern to VGA
Check Keyboard with challenge-response.
Check Mouse with challenge-response.
Send 1 kHz to Left => Silence => 2 kHz Right => Silence => Repeat..
Display joystick1 + joystick2 + keyboard + mouse
Testing FPGA:
Latch -> ALU+1 -> Latch -> ALU+1 -> Latch -> Repeat..


A test would be useful to test the board when building or when a malfunction is suspected.
