The board has an FPGA which contains the \"magic\", an analog path, and a digital path to the outside world. The digital path needs a 3.3V/5V interface. There are two opamps that serve as filters with gain. There is a need for several (3-4) LDOs.

I\'m waiting to hear back from someone from Renesas, who can discuss this with me, or a disti FAE. There are a lot of questions about how to turn these into a custom part number to meet my needs.

Anyone have experience with using these in production?

If you want to ensure \'N\' is an accurate assessment of their
\"usage of your design\" (royalty), then you need to be a gatekeeper
for something that is related to N, in some way.

One of the simple ways is a single unreadable programmable component
that you retain control of and supply one per unit made. Once you
share your secrets with a third party they can clone the thing as they
wish.

Yes.  Dallas (?) made some \"unique 1-wire coins\" that had individual codes
that you could recognize in software -- with a suitable polynomial.  This
allowed you to ship a coin as an activation token for your product.  Or,
as a REactivation token (e.g., for timed licensing)

....

But, if they can read the source code, then they can *see* what you are
doing.
if they want to eliminate that (artificial) dependency (\"to cheat you\"),
they
can easily do so.

Exactly my original point - unless the secured device implements some
critical function, the design can be changed to eliminate the need for it.

Ricky is still approaching this as an engineer, not a business-man.
Don and I have both been telling him that you can really only approach
this problem with trust and contracts, not hardware. Unless he makes all
the hardware himself.

We have handled that using Escrow services. Simply archive a virtual

agency, and write the appropriate agreement dictating under what
conditions they can open the safe and to whom they should give a copy of
the contents.

Exactly right. Consider their motivational model, and write suitable

Escrow services have nothing to do with IT Protection contract

You don\'t need any third party, you need a lawyer to work for you to ink a contract and need your bank to get money paid back


----
Escrow services can allow money or documents to change hands without either party assuming any risk. An escrow service essentially acts as a disinterested third party and takes possession of the money or documents until the transaction is complete. In exchange for the services, the escrow service will generally charge a flat fee.

Exactly. My experiences predate the use of VMs so we just archived
copies of all the design documents and tools with legal terms defining
how they could be reclaimed -- and by whom. The customer really did
not want to NEED to exercise this option -- cuz it means a big headache
for them as they don\'t have the expertise to even understand the
material archived. *But*, it\'s \"insurance\"; you don\'t want to make
a 30 year, 7 figure investment in equipment and discover that the
vendor went out of business 2 weeks later!

Locked hardware is just an invitation for them to break it.

Locked hardware (or software) is often far easier to break than
one imagines. Unless you\'ve actually sat down and made it a GOAL
to crack something, you likely don\'t realize how resourceful you
can be in such attacks!

And, the business isn\'t the same as the *staff*, there. Some
precocious engineer may want to dig into your \"secrets\" just
as a challenge. And, once he\'s cracked them, it\'s highly
unlikely that he\'s NOT going to tell others what he\'s learned!

\"Trust\" (mistrust?) needn\'t be based on whether or not the
party is ethical, scrupulous, etc. Rather, you have to
evaluate how much \"faith\" you have in their assertions.

SWMBO often misplaces kitchen utensils. (I never \"clean up\". Our
arrangement is that I will cook, bake, wash dishes/utensils -- but
not put stuff away or clean the {counter,stove}tops.) When I go
looking for something and can\'t find it WHERE IT IS SUPPOSED TO BE,
she will swear up and down, \"That\'s where I put it!\"

And, I\'m sure she *believes* that!

But, I don\'t TRUST these assertions. It\'s not that I think
she is lying. Or, trying to screw me over. But, too often, I find
things in some other place -- possibly because she was distracted
when she put it away and *forgot* the fact that she had misplaced
it there.

Showing her where I eventually find it usually is met with
a simple, \"Oh... I must have put it there when I...\" (the
fact that she\'d JUST SAID otherwise magically gets ignored)

OTOH, if I was unable to speak for my own medical needs, I would have
no problem \"trusting\" her to \"do the right thing\" -- whatever that
might be in those circumstances. Regardless of her own personal
preferences/biases.

blah blah blah

if contract value is T$100 or more, you need IP lawyer to work for you.

If you are a small entity you can hire bigger third party to buy and resell your IP, making margin profit, taking your risk.

Anyway, with every problem you finish in a court, what is highly expensive for a small entity.

So small entities enter into small low-risk contracts or build a company to make big money.

Most of the projects I\'ve worked on in my (relatively short with respect to

agreed price and the design is yours to do with as you will\" and handing off.
It\'s the terms a number of clients tend to prefer, I charge them
one-time-big-price and they seem comfortable with that.
I think it\'s easier. You charge enough to make it worth your while.
THEY know what it will cost them. If they go on to make big money
on the product, so be it. They\'ll have been happy to have worked with
you. If the product flops, its hard for them to rationalize that they
paid you too much (they knew the price, up front).

I can\'t charge as much for the design as I can make on the sales, nowhere near. I\'ve made around $4 million on the current board, maybe $5 million, I don\'t think I\'ve added it up. I think the sales have been around $7 million. I expect the sales on the new design to come close to that over the next decade. There\'s no way I can get them to pay me anything like that, for the design.

I can get them to pay for the boards if I make them. So far, they\'ve been happy to pay what I ask, because they have so much markup on the product my boards go into.

Once they look at manufacturing costs, and see a very low number compared to the price charged, the jig is up. I\'m pretty sure they won\'t bother looking at manufacturing costs until they have a need to. Either way, the agreement has to be strict enough, that even if they make the boards, I get my share.

This makes me think the two customized chips will need to have a significant price, enough to take the edge off what I want as a royalty, but not so high, they want to ditch them. Maybe, make one more expensive than the other. But first, I need to get Greenpak to talk to me.

To fake something you have to pass it off as something which it isn\'t, and what a a posts is such bare-faced idiocy that it won\'t pass as anything else but idiocy.

A a may be stupid enough not to realise this, which would make him a faker-manque.

The board has an FPGA which contains the \"magic\", an analog path, and a digital path to the outside world. The digital path needs a 3.3V/5V interface. There are two opamps that serve as filters with gain. There is a need for several (3-4) LDOs.

I\'ve found a couple of chips from Greenpaks that could help here. One is a \"Programmable Mixed-Signal Matrix\" which could replace the opamps and provide a configurable gain using the programmable \"rheostat\". Another has four LDOs which would be useful and *might* be able to serve as the level shifter.

I\'m waiting to hear back from someone from Renesas, who can discuss this with me, or a disti FAE. There are a lot of questions about how to turn these into a custom part number to meet my needs.

Anyone have experience with using these in production?

Please let me know if you\'re able to get anyone and how it goes, It
seems like the Renesas acquisition of Dialog\'s lineup has been sloppy as
hell

I thought someone here has used the Greenpak parts before. Maybe it was another group.

BTW I noticed you talked about level shifting, a number of GreenPak
parts have dual supply pins and can intrinsically level shift between
3.3 and 5V, you put your 3.3 I/O on one set of color-coded pins and the
5V on the other set, easily done.

Nah it was me (though there another guy here who\'s used them also, \"BoB\"
I believe.)

I\'ve done a number of designs with them in the past couple years so if
you have any questions I might be able to help.

I\'m a bit unclear about the programming. When they have an I2C port, does that mean they can be programmed via that? I\'m looking at the SLG47004 and SLG46580. Can the SLG46580 LDOs be set to power up to a given voltage? I don\'t see a means of sequencing the power up of the LDO, other than perhaps through the I2C port. They talk about writing to registers that reflect the non-volatile memory. It\'s not clear if there are registers that are not loaded from the NVM.

Do all of their parts have factory programmed NVM? Do their parts let you configure everything from the I2C port, or do the parts need to be replaced when reprogrammed?

Whew! I started typing this around noon and have been slammed all afternoon!

Looks like the respin is going to be rewarding. They are talking about 18,000 units next year and more in the following two years! I just need to design it with an FPGA that I can actually buy, not to mention the other parts on the board. I hope the availability of the Greenpak units is not too bad.

I don\'t think the parts that are otherwise useful have the dual voltages. I just need 3.3V I/O that are 5V tolerant. I\'m not finding that on the parts that otherwise look interesting.
