Honored ContributorI worked my way through the tutorial, no problems till I got to the code development on the Eclipse based tool. It almost worked, various errors when trying to download to the chip. I was using an eclipse workspace that is shared by other tools I use, ARM, MSP430 etc. Creating a new workspace just for the Altera/Nios stuff fixed it.
I managed to delete the JTAG UART and replace it with a generic UART and got that to work through the DE0 UART hardware. :-) (small victories...) I still have no idea how to do any timing analysis, need to study that. Need to keep studying Verilog. I am not sure how to implement large parallel IO ports and to translate them to a buffer. These would come from ADCs and there would be, I assume, some sort of clock and strobe signals... A lot of this feels very dubious in that developing this way is SO dependent of fixed software tools, so much of it consists of "black boxes". I worry that if something breaks I will not be able to fix it. Like the random error messages from the Eclipse tool that I eventually fixed by creating a new workspace. I am used to microcontrollers where the hardware is fixed and I have my choice of many tools. I am also concerned about IP pricing. The Altera website is TERRIBLE, why don't the have a simple pricing matrix? Rich
