Abstract

This paper presents a new technique for iterative decomposition of multiple-output Boolean functions with an embedded heuristics to order variables. The algorithm produces a cascade of LUTs that implements the given function and simultaneously constructs a sub-optimal Multi-Terminal Binary Decision Diagram (MTBDD). The LUT cascade can be used for pipelined processing on FPGAs or at a non-traditional synthesis of large combinational and sequential circuits. On the other hand, suboptimal MTBBDs can serve as prototypes for efficient firmware implementation, especially when a micro-programmed controller that firmware runs on supports multi-way branching.  A novel technique is illustrated on a practical example of the m x n wavefront allocator (m = n = 4, 20 inputs, 16 outputs). It may be quite useful as a more flexible alternative implementation of digital systems with increased testability and improved manufacturability.
