Hi all, I'm looking for a sub-$20 FPGA board (including everything needed to actually use it). Requirements: * The device must have reasonable free software that can handle schematic capture and Verilog (Altera and Xilinx would be easily sufficient). * Can manage at least 1K gates and 20 flip-flops.
Strongly desired: * At least one debounced button useable on a GPIO line (not reset for example) * At least six switches readable by the FPGA. * At least six LEDs writable by the FPGA. * At least four GPIO pins that are reasonably accessible. * Actually costing closer to $10. * Can power off of USB without any other supply. * Can manage at least 5K gates and 50 flip-flops.
Would prefer: * At least twice as much I/O as described above. More is better. * Compatible at some level with some larger FPGA line (Altera DEx line in an ideal world).
I'm going to go vendor shopping in a few weeks, but I thought I'd see if anyone knows of anything close to this that's on the market.
We'd be looking at around 5K-15K ordered, all for academic purposes. Failing finding a board, we are willing to design and manufacture our own (as a far second choice). So suggestions on parts would be welcome.
Also, any thoughts on using a cheap microcontroller to emulate an FPGA would be of interest.
I've found some things that aren't all that close. * Digilent C-Mod -- $22 in quantity of 1, needs external programmer, no I/O on-board AFAICT. * Polmaddie2. No switches, way too much $$$, but pretty good otherwise. Way more GPIO/FPGA than we need.
Thanks in advance, Mark
