ATF1500ABV Macrocell
10. ATF1500ABV Macrocell
The ATF1500ABV macrocell is flexible enough to support highly complex logic functions operat-
ing at high speed. The macrocell consists of five sections: product terms and product term select
multiplexer; OR/XOR/CASCADE logic; a flip-flop; output select and enable; and logic array
inputs.
10.1
Product Terms and Select Mux
Each ATF1500ABV macrocell has five product terms. Each product term receives as its inputs
all signals from both the global bus and regional bus.
The product term select multiplexer (PTMUX) allocates the five product terms as needed to the
macrocell logic gates and control signals. The PTMUX programming is determined by the design
compiler, which selects the optimum macrocell configuration.
10.2
OR/XOR/CASCADE Logic
The ATF1500ABV macrocell’s OR/XOR/CASCADE logic structure is designed to efficiently sup-
port all types of logic. Within a single macrocell, all the product terms can be routed to the OR
gate, creating a five-input AND/OR sum term. With the addition of the CASIN from neighboring
