Verilog HDL(SPI) help needed

Hey guys, I'm trying to write a code of SPI, and I have 0 experience in this :

The device needs to be designed to provide translation between the RS232 and SPI protocols in
either one of the following modes:
• A1 is a RS232 receiver. It will receive a serial bit-stream from a PC and perform the
necessary error checking on the data. It will then pass the data onto A0.
• A0 is a SPI transmitter. It will receive the data from A1 and convert it into the SPI protocol
bit-stream and transmit it onto B1. It will function as an SPI master device.
• B1 is a SPI receiver. It will receive an appropriately formatted SPI protocol bit-stream and
pass it onto B0. It will function as an SPI slave device.
• B0 is a RS232 transmitter. It will convert the data received from B1 into a suitable RS232
bit-stream and transmit it onto a receiving PC.

Which looks something like this:


I've found codes of writing SPI in: fpga4fun.com - SPI - A simple implementation

Now there are two problems, how do I show it on an Altera DE1 Board, since there are no indication of which pins are the MISO,MOSI, etc....
And, how do I write codes for SPI master device?

I don't understand the question.

If you don't know verilog, you can't.
