Re: Quinn-McClaskey Algorithm?

[luciano@canuck.Berkeley.EDU (Luciano Lavagno)]

I know this does NOT strictly belong to any of the groups I am posting
it to, but many people are asking information, so I will try to settle
the question.
1) the Quine-McCluskey algorithm is a well known algorithm to obtain a
minimum sum-of-products (e.g. f = a b' c + a' b + c') representation
of a logic function
(that is a function with domain {0,1}^n and range {0,1}) from an
initial non-optimal sum-of-products representation of it.
This finds applications mainly in combinational logic circuit
synthesis (but not only there...).
2) the best implementation of this algorithm that I am aware of, is
part of the "espresso" logic minimization program. It is available
from this university for a nominal fee (there is also anonymous ftp,
but that's a bit trickier...). Just send e-mail to
erl@janus.berkeley.edu and ask them. Let me know if you have any
problem...
