This build took 11 hours on an Intel Skulltrail NUC w/ 32 GB DRAM, but I believe there are ways to speed this up going forwards (incremental and/or hierarchical builds, out of context synthesis). For example, the XCVI9P is a 3 die (3 "super logic region") device and by setting up a hierarchical design flow I think I can place and route each SLR separately (at the same time) across more (x86) cores on my build box. The inter-SLR interconnect nets are just some quite regular 300b wide Hoplite NOC links and clock and reset.
