* Initial lookahead for FPGA interchange.Keith Rothman2021-03-231-0/+400
Currently the lookahead is disabled by default because of the time to compute and RAM usage. However it does appear to work reasonably well in testing. Further effort is required to lower RAM usage after initial computation, and explore trade-off for cheaper time to compute. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>
