Mr. Usselman, Hi. I saw on your website that you've successfully tested the USB2.0 IP core on a Xilinx Spartan 2 xc2s50-6. Where you able to test it on a whole system? What PHY IC did you use? Also, is it possible for you to provide the testbenches you used in verifying the core? Thanks. -- To unsubscribe from usb mailing list please visit http://www.opencores.org/mailinglists.shtml
