- Using the Minimum Set of Input Combinations to Minimize the Area of Local Routing Networks in Logic Clusters Containing Logically Equivalent I/Os in FPGAs
- Mapping digital circuits onto field-programmable gate arrays (FPGAs) usually consists of two steps. First, circuits are mapped into look-up tables (LUTs). Then, LUTs are mapped onto physical resources. The configuration of LUTs is usually determined during the first step and remains unchanged throughout the second. In this talk, we demonstrate that by reconfiguring LUTs during the second step, one can increase the flexibility of FPGA routing resources. This increase in flexibility can then be used to reduce the implementation area of FPGAs.
