Oh, a USB PHY chip. Yeah, that might be the way to go now that we're not counting I/O pins. >> 1:1 block mapping.

Partly it's a challenge and partly it's something I'd like to have around for another project. > Please do yourself a favor, and put a small micr0controller in the FPGA. > Get it working, then you can optimize and write HDL for it. We've talked about a soft microcontroller, an actual microcontroller, and just writing it in some sort of microcode. Want to get the SD card working first so Noel can start using the prototype board as an actual storage device. > What FPGAs are you using? Xilinx Artix 7. More specifically, we're using a ZTEX 2.13 FPGA module for our prototyping. Unless some good reason came up, I was thinking to stick with the same FPGA.
