(ref: https://news.ycombinator.com/item?id=33032036)<p>I'm looking for multiple FPGAs on a single board. The prior request got only a single response, the HTG-847 ( https://www.xilinx.com/products/boards-and-kits/1-fb2a7b.html ). However, the board is too expensive and could not be programmed by open source software.<p>The ideal case is a single board with 4 chips (and a scalable design to other powers of 2).<p>The goal is a board to experiment with various software / hardware architectures that is fully programmable.<p>The only solution seems to be to create such a board. At the moment I'm looking the Artix 7 100T chip
(https://docs.xilinx.com/v/u/en-US/ds181_Artix_7_Data_Sheet). It can be programmed with open source software.<p>Suggestions, comments, and snide remarks are most welcome.
Any board like that would probably be extremely niche and thus expensive, since there is no obvious "correct" way how it should be done for a general case.<p>I'd look into finding a board with little extras and wiring up (potentially through a simple backplane) multiple ones of those. Or go for one big FPGA and just run different topologies between components inside that.
