NAME
minterm - minterm file format
DESCRIPTION
The minterm file format consists of at least one binary valued function
definition. A function definition begins .o n ... followed by line(s)
that have the form term:mask ... The first n following .o is a numeric
symbol of the function (usually an output pin number of a rom or pal
integrated circuit). Any other n's are numeric symbols of input binary
variables. Term and mask are decimal numbers.
There is a correspondence between the bits of the numbers in binary
representation and the input symbols, the first input symbol is associ-
ated with the least significant bit. The meaning of a bit with value 1
in mask is `do care', and the meaning of a bit with value 1 in term is
`input must be 1'. Thus the term:mask is a implicant, and a set of
them when or'ed together describes the input conditions for which the
output symbol will have a value of 1.
For example:
.o 3 1 2
3:3
.o 4 1 2
1:3 2:3 3:3
.o 5 2 3
1:3 2:3
.o 11
.o 9
0:0
Output 3 is the and function of inputs 1 and 2; output 4 is the or
function of inputs 1 and 2 (quine(10.1) would change this to 1:1 2:2);
output 5 is the exclusive-or function of inputs 2 and 3; output 11 is a
constant 0 and output 9 is a constant 1.
