Why don't manufacturers don't offer device libraries? Surely they've
got the most to gain by making it easy to drop-in their products. Maybe
they don't think it's a factor in product selection; maybe they're
right. (I'm not just talking about the package footprint, but the pin
assignments, ERC attributes, etc.)
It sounds common to set aside a library of "trusted" devices that
survived a board spin without a glaring defect. I don't know that I'd
change this approach, but I'd trust a library from the manufacturer more
than one created from a datasheet by me or the EDA vendor.
What about devices for Spice models? I'm not a Spice user (yet), but
this is something else that's traded on the underground instead of just
provided by the manufacturers...
I talked recently with the (marketing) guy that owns the website for a
large mfr. They're re-designing the site to be more "designer-centric",
and shoving the marketing / corporate glitz to the background, which
seems like a smart move. They claim to be doing the whole thing based
on focus groups with real designers, supposedly even ignoring internal
opinions. I'll be interested to see the result.
I mentioned the idea of providing device libraries for download, and he
swears not one person mentioned it as a nice-to-have during their
research. Is this just so status-quo that nobody thinks to ask for
them, or am I missing something?
