Wow - that TCL script is pretty handy and worked first time! Really impressive! Ok, I've sucessfully downloaded your basic program into my nano, and it works well. There was a single curious item: my first attempt (Start...) failed. I tried the other modes, of which only passive serial was available, and it failed as well. I then tried JTAG again, and it programmed immediately; the LED counter ran as expected. I've reviewed the code, and as you mentioned, it is pretty rudimentary but very easy to comprehend. What I'll continue to review this morning is your SDC file and how to define the pins assignment/layout (something that I'm not yet familiar with). (It is obvious that I need to add TCL to my programming languages. I've noticed that it is the programming language in Quartus, so it makes sense to learn it as well.) Oh, one other short note: I'm not really new to FPGA devices and programming. My first design (a pair of Xilinx FPGAs) was done in the late '80s and a second design (can't remember if it was one or two Xilinx devices) was done in the early '90s. Of course, the tools have improved dramatically since then! I'm simply trying to catch up on the new stuff ala Altera. Thanks so much for the work that you put into these samples/templates! They both are very useful to me now. If you are ever in Plano, TX, I owe you lunch! Dave
