Bottom up synthesis based on fuzzy schedules

Tai A. Ly, Jack T. Mowchenko
1991 Proceedings of the 28th conference on ACM/IEEE design automation conference - DAC '91  
In this paper, we present a new bottom up synthesis formulation designed for full allocation of data path operations and data values prior to scheduling.  ...  This work is novel because it treats unscheduled operations as having uncertain schedules, then applies fuzzy set theory to quantify these uncertainties during allocation.  ...  Discussions In this section, we compare fuzzy allocation with probability based bottom-up synthesis [lo] and with design partitioning [71.  ...
