PHIPLA, a new algorithm for logic minimization, is presented. The algorithm sets out to find optimal sum-of-products representations for a set of Boolean functions, thus contributing to area minimization of the Programmable Logic Array corresponding to the set of functions.  The results of a comparative study of PHIPLA and two other algorithms, SPAM and PRESTOL-II, are presented. From these results it is concluded that PHIPLA generates representations which are competitive with those generated by SPAM and PRESTOL-II, whilst the algorithm is extremely fast for small problems (up to 12 variables).
