Abstract

In this paper we define and study the properties of projected don't cares, a category of don't cares dynamically built by the minimization algorithm during the synthesis phase. Our target is to exploit projected don't cares properties in order to obtain more compact networks. In particular, we show the use of projected don't care conditions in two synthesis techniques, i.e., using a Boolean and an algebraic algorithm. Experimental results show that in the Boolean case 65 % of the considered benchmarks achieve more compact area when implemented using projected don't cares. The benefit in the algebraic approach is reduced (35 % of instances benefit from the proposed technique), even if there are examples with an interesting decrease of the area.
