Are there an simple but complete VHDL projects available for Quartus 14.0 that include a VHDL test bench file? Simple meaning that the design is a counter or shift register. It has been about 10 years since I used Quartus and it is very different. I would like a known good project to experiment with to get started again. Ideally a zip file with all the files and sub-folders already in the correct places. Scott

Hey Scott, Do you have a development kit? If so, which one? (I might have an example project for it). Cheers, Dave

Dave, This is my second reply. The first one hasn't shown up. I ordered a Terasic DE1-SoC. Using their golden top file I then translated it into VHDL adding some code so that a counter would cause some of the 7 segment digits to count up in hex. I am using the web tools for now. The code compiles without problem. Now I was trying to create a test bench. Most of my simulation experience was with .VEC files in the Maxplus and Maxplus II days. Scott

Hi Scott, --- Quote Start --- I ordered a Terasic DE1-SoC --- Quote End --- Sorry, I don't have that one :) --- Quote Start --- I was trying to create a test bench --- Quote End --- You've got several options, depending on how complicated your system is. For example, lets say you use the ARM processor on the SoC and you connect to your hex display. What should you simulate; 1. Everything? Eg., the whole ARM processor including booting U-Boot and/or Linux, and then running an application to toggle the I/O connected to your display 2. The specific component you just designed? Eg., create a testbench with the hex display and the bus interface used to read/write to the hex display registers. Obviously (2) is what you really want to look at. The bus interface is what you really want to understand how to simulate, as once you understand how to interface your hex display to the ARM core, you've got the basics for interfacing anything. You've got a couple of ways you can interface to the hex display from a Qsys system (Altera's system builder); 1. Use an existing component such as the PIO core, and then use that to control your hex display 2. Create a _hw.tcl file that descibes your hex display as an Avalon-MM or AXI component I'd recommend understanding both methods. How does this sound? What parts of this description do you understand, and which parts do you not? Cheers, Dave

Dave, I picked that board because it has a 1MHz A/D. The code will eventually be for several faster A/Ds. Too fast for the ARM to be directly involved. So, initially I will be working in logic only. Any simple example (no CPU) will do for now. I can port it to the board I have. A counter or shift register or some other function easy to follow. Scott

ModelSim-Altera has it's own GUI. The tutorials I ran used that. I used to do everything command line driven but some tools I use no longer give that option so I am adapting.

Ah, sorry, I misinterpreted your question.

If you followed the Modelsim tutorials, then I think it produces a log file. If you look at that log file, it essentially uses all the commands I wrote in the sim.tcl script.

You can use the Modelsim GUI to build; hex_display_pkg.vhd, hex_display.vhd, and hex_display_tb.vhd, and then figure out whatever the GUI equivalent to "vsim hex_display_tb" is and then whatever the GUI command for "do scripts/hex_display_tb.do" is. Personally I've never had much of a reason to use the GUI "GUI" elements, when the Tcl console works great! (And arguably, it is part of the GUI) :)

Cheers,
Dave
