I need help just understanding this program for class

Hola Lew,

L Red. I need help with the compiling and doing the synthesis and the simulation. For instance, that program that I copied into the body of my post, I know that it compiled correctly, however, when I got to the simulation part it still gave me errors. Then I got those to go away (and I don't remember how), well after that I tried to run the program in hopes that I would either see a timing diagram or an actual circuit operation simulation. But, apparently I do not know what I am doing thus I am lost confused and frustrated!!!!! Is there an easier way to do this, something that has a step by step operation to it?

You sound pretty freaked out, which is certainly understandable if this is your first time seeing AHDL, and new to programming in general. I don't have much experience with AHDL, but I might be able to help you out (though I'm not promising anything).

Quartus. And yes I am following a lab manual and I am trying to figure out what all is supp0osed to be included say with rogramming a circuit. i.e., If I am told to design a circuit for instance. I need a circuit to provide a high when AB & ABC + !AB + C is true. I know how to write it using AHDL, but when I write it as a code, what is next, do I set it up for a timing analysis or can I actually build the circuit and see it perform with actual devices or can I set it up like multisim using schematic drawing and watch it perform. I am lost on seeing whether my programming is causing the circuit to actually perform the way that I wrote it. I guess that I am trying to figure out the steps and the process of actually completing or using the software to its full capacity. I hope I haven't confused you (as I am now confused). But maybe you can help???????

Whoa! You are indeed, in full freakout mode homie. So I take it this is for a class, and you're following every step in a lab manual? Moreover, I would imagine that the due date for this lab is fast approaching, which is only adding to your sense of panic.

1. Write a HDL program that describes the circuits function, debug it as necessary.

2. Do functional testing on your program to ensure that it functions as intended.

3. Once step two is done, a designer pics a programmable logic device, and then does timing simulation. Timing simulations are basically functional simulations but with timing delays between the input and outputs.

4. Finally the chosen device is programmed and actually tested for proper functionality. Of course, this assumes that steps 1 through 3 went off with out a hitch.

The above tdf file can be compiled as a top design file by Quartus, it can be also simulated by the Quartus simulator. What are you asking in particular?

teaching AHDL when the Altera simulator is slated to be discontinued is a bit worrisome.

A course that doesn't emphasize how an HDL is to be used is even more worrisome.

I concur, I concur. It is actually giving me the blues in all of my other courses. It's like I am having to learn to do 2 classes in one.
