Because it’s a personal project, this is going to end up being personal choice, but I also want to give a try to any language that has enough tool support to target Xilinx and Altera FPGAs. This will be obvious ones like VHDL and Verilog, or like myHDL, which first converts to one of the major languages prior to synthesis. I’d like to focus on languages that either have a current wide usage, or seem posed to get that sort of up take. But I’m also going to try to not spend a lot of time on any in the same class like C to hardware, or DSP / graphics controller language adapted for FPGA.
