Well, for comparison, the cost of a current 100K LUT FPGA on a board is: $250 for Xilinx Artix-7: https://store.digilentinc.com/arty-a7-artix-7-fpga-developme

- happycube 7y agoI haven't played with mine yet, but there's an open toolchain for the ECP5 :)
- panpanna 7y agoNote that you can't easily compare LUT count between vendors or even among a vendors different architectures. In any case, I think ecp5 is partially supported by open source tools which should make it much more interesting to hobbyists.
- freemint 7y agoAlso Lattice only does LUT4. (Their internal look up tables have 4 inputs) The Artix-7 has LUT6. From what i heard that means you need more than 1.6 times more LUT4 than LUT6. Not including the fact that Artix-7 includes other hardware features which are sometimes wired in to a desgin
