publishing IP

Hi

I am making a VGA display IP (receive caracter code in a buffer and display it on a VGA screen) , yet it's nearly finish (make some last parameters generics and make a documentation+ more commentary of my code) So my questions are

*What kind of licensing you recommend to me (if you think it should) , I dont want to make money, I make it just for educative purpose (and also to make me a name in FPGA world :) ) *I wanted to post it on opencores.org but the website seems to be laggy :/ anywhere else where I can post it??

As I finish that IP I 'm looking for new and interesting project does anyone have any idea of IP, I can do and test at home (I 've got the digilent spartan 3 board) ?? I was thinking of doing a PS/2 keyboard interface and RS/232 port for trying to make a kind of SoC , what do you think about that??

Regards,

Alexis

There are a couple of common licenses that may be appropriate - some of them may even be in use (modified) for use specifically with ip cores - opencores.org should have some :) (IIRC).

You could consider the (or a) BSD-style license - This basically lets anyone do anything with the code - they just have to retain your copyright notice on it (AFAIU).

or you could consider a GPL-style license - This puts several restrictions on what people may do with it - such as requiring them to release source if they modify it, and restricting what they can integrate it in to without releasing source.

One thing I guess you could consider is that the GPL can make things difficult for companies that want to integrate your IP block into a commercial product, because of the requirement to redistribute source code.

You could also just make the code completely public domain (or write your own license)- there are pros and cons to each of these approaches.

Good luck :)

Hi,

Try an ASCII terminal implemented on the Spartan-3 Starter Kit. Go to

and look at Lab #7. It is a fun project. I tried it myself, using PicoBlaze.

Well, not a big problem. Such companies are free to contact the author for a different licensing of the same source if they have different needs.

That is true, yes. It is something that definitely needs to be handled before work starts though, otherwise it's just a risk factor :) I guess it would be no more work than buying an IP core, except that there's no guarantee of getting a different licence.

Only true if the gpl licenced ip comes to them unmodified.

because the modified (improved, hopefully) version of your IP is not _your_ IP anymore. It belongs to all contributors.

But what are the other choices ?

You can't reasonably suggest other people to improve your work and claim all rights over what they did. That means a "use as is but no right to modify" licensing. So, no improvement to expect.
