Optimally solve LUT mapping and retiming simultaneously; there are so few things we can solve optimally, and so few things we can afford to address together, it’s refreshing see formulations where you can provide optimal results across multiple traditional levels of decomposition. As with flowmap, there are later papers which take this further and provide more efficient and general solutions, but the earlier papers introduce the cleanest problems and key ideas.

Since interconnect is the dominant area (and delay and energy) contributor on FPGAs, architectural optimizations which try to provide adequate interconnec to use all the logic may quite inefficient; this paper turns the question around and asks how the two should be balanced together. This provides a clean, parameterized formulation of this tradeoff.
