 it depends on what you take into account.  if someone else pays the
NREs to the foundry, i.e. a university agrees to collaborate and is
offered access to a foundry for either free or at reduced rates,
$250k-$500k comes off that amount, straight away.

 if only wanting to reach a target of say producing the design files
(HDL), that's a different target entirely as well, and if someone else
can take over at that point (and make the actual money selling
product), then that's one way to ensure that the goal's reached [but
not guarantee financial benefit from it].

 so it was a throwaway comment written in about 30 seconds with no
strict analysis done.  last time i collaborated with an associate to
come up with a proper figure it was around USD $5m (for a client) and
it took us around five days to put that together.

 however that particular deal excluded certain resources and had
specific requirements.

 excellent.  well, when that happens, let's talk (on or off list), you
let me know what you can raise and i'll put the time in - which will
be several days not a few moments - to work out what can be done, and
what side-deals will be needed, if necessary.
