Selling Microblaze based Machines

Are you using the cores in an Altera part? ;-) Cheers, Syms.

I think Xilinx's stand is if you sell a core that targets a Xilinx FPGA or CPLD fabric they don't care.

Xilinx is in the business of selling parts not microblaze or Picoblaze IP.

And since without major modification the Microblaze and Picoblaze are a Xilinx only core, you have nothing to worry about.

Eric,

Correct. We want you to sell lots of silicon (that we provide). That is why many (most, almost all) of the Xilinx IP has a 'license once, use as much as you like in a product' agreement.

There are some fine points:

(d) ?Licensed Project? means a project using the Licensed Materials to create (i) a single bitstream (using one or more instances of the Licensed Materials) for use in one or more printed circuit boards; or (ii) one or more bitstreams (using one or more instances of the Licensed Materials) for use in a single printed circuit board. Derivative or follow-on projects, with the exception of bug fixes to remedy errors in Licensed Products, are not part of the Licensed Project as defined herein.

So, we do like to see some revenue from you using the core again in another pcb or project...seems fair?

All of the details:

Aust> I think Xilinx's stand is if you sell a core that targets a Xilinx FPGA

To clarify this "?Licensed Products? means any integrated circuits manufactured by Xilinx that are programmed with a bitstream generated by use of the Licensed Materials."

Yes, but that is not quite what the legalese actually says:

Any significant revisions of either PCB or Software seem to be excluded. Indeed, even bug fixes are only allowed on the Xilinx flows, not to the users designs!!

In fact, given that "Licensed Products" does _not_ include Xilinx SW, this seems to say the ONLY exception is Silicon related bug fixes!

Under this wording, Xilinx can legally charge you again for SW bug fixes.

Seems that even Version improvements are also excluded ?

Now, one hopes Xilinx does what Austin says, and not what the agreement states, but some legal depts might worry about that.

Of course, Xilinx could rewrite that poor wording.....

Jim,

I suggest those who are serious about these sorts of legal agreements hand the agreement to their company's attorney.

I gave only one example, of a 'project license'. There is also a 'site license'.

So far, 97% of them like the agreement enough not to mess with it.

If you don't like our terms, then we are more than happy to agree on terms which will make both you and Xilinx happy.

Austin
