What parts do
not have published programming algorithms? I you are buying your
I have yet to find a reasomably complex PLD (that is something more than
one of the ispGALs) that is 100% documented. That is to say that you can
go from logic equations to chip without any proprietary software, either
the logic compiler or the programming software.
I would love to be wrong about this -- if anyone knows of such a device,
let me know, please!
own parts, just avoid chips or manufacturers that
don't provide this
information.
