FIT PLA We want to realize, with the help of a FIT PLA structure (according to the structure described in section 14.4.2), a set of 210gic functions,fl andj2, expressed by the list of their true vertices (noted here R(i, j, .. )):

fl

(a,

b, c) = R (2, 3, 7), j2

(a,

b, c) = R (3, 4, 5, 7).

1. Determine the number of product terms necessary to implement these two functions in a PLA.

2. Give the symbolic structure of the resulting FIT PLA, by inc1uding the parity lines.

3. Find the complete test sequence of this circuit by indicating the faults detected by each vector.
