What I would like to do is start a thread on this where I can post everything we're doing step-by-step for others to follow along and perhaps even suggest improvements. I'm not concerned with any actual finished product at this time. In short, this entire project is just for leaning how to program the Cyclone II efficiently. Then I can go back into the VHDL and see what I would need to do there to reproduce the schematics I created by hand. The reason I want to do this is so I can work in schematic mode for a while to see if there are ways to reduce gate count in the design. My ultimate goal is to re-design this entire project using the schematic alone without typing in any VHDL. For some reason I'm just not having any luck connecting individual pins to a bus. I understand electronics and I've worked with many schematic programs in the past so it's not that I don't understand schematics. Well, for one thing, I'd like to learn how to work with the Schematic diagram better. I have a specific goal in mind that I would like to achieve. And then I wanted to modified the schematic, but I'm running into problems there when I tried to break out pins on a bus.
I was able to create a schematic file using the original VHDL code. However, in spite of the great success up to this point I still have a lot of things I'm not understanding.
In fact, I even modified it some to do a few different things and to my utter shock and amazement even my modifications worked as expected. I typed it all in, complied it, downloaded it onto the board, and it does exactly what it's supposed to do. I've typed in a VHDL hardware description from a YouTube tutorial that uses the same software and the same board I have.
I'm hoping to find other hobbyists who could help me learn, or perhaps we could learn together? So far I've installed the software and USB Blaster. The boards I have: FPGA Altera Cyclone II EP2C5 CPLD Altera MAX II EPM240 I'm totally NEW to this so I have almost no clue what I'm doing. I've just downloaded Altrea's Quartus II version 11.1 software to program some Cyclone II FPGA boards I have.
