How to make custom target board?

I usually received this message when my processor was not functioning. There may be many reasons for it.

If you already tested a working processor design with the board than, check how you connect reset, some of my designs worked with the reset_n connected to VCC but lately I usualy have to use a timer generating a reset pusle (I am not sure it this timer is realy needed, since at the same time I changed the chip from Cyclone to Cyclone II and changed Quartus to a newer version).

If it is the first time you try to start the board than:

- check power supply

- check if you get the clock (connect a blinking led to a timer connected to the clock)

- check the reset signal for the processor

- try a processor without an external chips, use internal RAM (this way you know that at least the Altera chip works)

- try the full design
