*nod* Fair enough. I want to be proved wrong here. :-)

No. I may end up there in about four months, though.

*nod* My experience is that support is always non-existent, for just
about anything. :-P No matter what you pay for or who you talk to, it's
not worth the money or time. You get any source code and documentation
you can and you figure it out.

Fair enough.

*nod* OGP would need 10 customers like you to make a go of this,
ignoring NRE costs, which will still be huge. I hope I am too
pessimistic and there is a chance here...

Sure. Cell ASICs fit inside that bracket easily. I looked at having one
made around a year ago, and a 50K gate design was a $2.50/part in 10K
lots, I think, and NRE was quite reasonable. 200MHz was quite reachable
too, and the had onboard PLLs.

This is one of my problems with the OGA design.. I think it's too much
with too high NRE costs...

Cheers,
