Hi JW,
thank you bery much for the advices, very usefull. Thanks to you and to Dan for having continued the discussion. Unfortunately, the approval system doesn't let me to answer reactively to the posts.
However, at the university I used Altera Quartus II for a very little project, and the integrated simulator (modelsim). One month ago, during my personal study, I tried to use GHDL with GTKwave but I had some troubles.
I have a question for you: you suggest to use ISE, and Vivado only when it will be necessary. But in the Xilinx website, I see that ISE is no longer supported from 2013, and the suggested software to use is Vivado. In order to use my own study to let me hire, isn't better that I use a software that is supported by the Xilinx and, I suppose, used by the industry?
However, thanks for the suggested books. I'm now studying on "Hubert Kaeslin-Top-Down Digital VLSI Design_ From Architectures to Gate-Level Circuits and FPGAs". Is a really good book from my point of view.

Sounds good to me. The more, the merrier. It's a pity this forum has no private message feature.

Let's get in touch. But in order to prevent pubishing our private e-mail to the whole internet shall we contact via linkedin? You can find me with my last name: G r i m m e r

Cheers,

Not quite: everyone on OpenCores has an OpenCores e-mail forwarding address. Private messages can be sent via these addresses.

Hi Dan, thanks for the hint. I was not aware of it, but it is actually stated in the Site FAQs, just that it is all the way down:


I wonder why that is not stated in the personal account info page or in a welcome message when creating the account, it's such a central piece of information. But maybe I'm just a moron ;-) Anyhow, thanks a lot.

Daniele,

If you've been paying attention, since you wrote there have been several requests for help. The most recent request has been for an OpenCores huffman encoder. Sounds simple enough. Anything you are interested in?

There's also been an interest expressed in a working PCIe controller, as well as getting Linux running on MinSoC.

Please consider yourself invited to play a part!

Yours,

Dan

Hi Dan,
thank you for the advices. In these day I did some simple design in Vivado, to take confidence with VHDL, that I was forgetting. I did a very simple shifter, but parametrized. I want to realize a parallel, pipelined and parametrized multiplier, but I'm struggling, and also I don't know if it is usefull (indeed, I'm implementing a multiplier of 2 number of N and M bit respectively, unsigned, and the output is M+N bit long to avoid the carry and then to perform the sum full parallelized, but I guess that this solution is senseless. However, even if I would implement for a Learning scope, I'm find some issue in generate the structure of the following adders (attached file).
However I did correctly the shifters and a testbench for the sifters. I'll take a look at the project you have mentioned.
Cheers,

Daniele

Daniele,

Building a multiply within Verilog/VHDL is a fun topic that I would like to participate in. It just doesn't seem appropriate to continue this thread with it.

Want to start a new thread? I can tell you of my experiences ...

Yours,

Dan

Even I am in for a team to learn working on basic projects!! I am a graduate student majoring in digital design and I am not convinced enough of my RTL coding skills. I always look up to a group which is willing to learn and share ideas! Let me know if a group is being formed and a project is decided! I am pretty much open to learning any new stuff to start off with!

Bhaskar

Ok Dan, it's a good idea. I'm going to open a new thread.

Hi Bhaskar,

We are currently 3 guys (deltax, srinivasbakki and me) trying ourselves on a fast integer division core with modulo. We thrive to make one division operation in as few cycles as feasible, the core being fully parameterized and staying true with the euclidian definition of the modulo operation.

This might have been done numerous times before and even trivial for some, but for us it seems like a good starting point.

Want to join?

Cheers,
Roland
