Abstract: Embodiments herein are directed to systems and techniques for supporting heterogeneous logic architecture in programmable devices, such as field-programmable gate arrays (FPGAs). heterogeneous logic architectures may include additional logic elements (e.g., AND-inverter cones (AICs)) in addition to lookup tables (LUTs). Accordingly, it may be desirable to provide a compiler flow that supports heterogeneous FPGA architecture, taking advantage of a combination of LUTs and other logic elements (e.g., AICs) to improve resource utilization (e.g., die area, wire length) and improve maximum clock frequency and compile time.
