Foldback Bus
Figure 1. ATF1504AS Macrocell
0950N–PLD–07/02
Each macrocell also generates a foldback product term. This signal goes to the regional
bus and is available to four macrocells. The foldback is an inverse polarity of one of the
macrocell’s product terms. The sixteen foldback terms in each region allow generation
of high fan-in sum terms (up to sixteen product terms) with a nominal additional delay.
