FPGA: ECS Introduction The Xlinix WebPACK tools come with an editor called ECS, "Engineering Capture System." Basically, this is an editor that allows you to create modules (Verilog term) or entities (VHDL term) by drawing schematics. Yes: by drawing schematics you can program your FPGA. It's way powerful. I just discovered ECS the other day. I wired up an ALU to some external connections. It wasn't rocket science, and learning was slow. But this web page will describe how to do the same thing. I will include a copy of the project, as well as just the source code. My goal with this web page will be to allow others to get a start using the ECS tool.
