Yamashita et. al.  introduced a new category for expressing the flexibility that a node can have in a multi-level network. Originally presented in the context of FPGA synthesis, the paper has wider implications which were discussed in  . SPFDs are essentially a set of incompletely specified functions. The increased flexibility that they offer is obtained by allowing both a node to change as well as its immediate fanins. The challenge with SPFDs is (1) to compute them in an efficient way,doi:10.1145/288548.288584 dblp:conf/iccad/SinhaB98 fatcat:xryygwnusjcs5p5jfx2gyzqqge
