Hello, my name is Lukasz Kielbowicz and I am a student of Wroclaw Technical University. I came from Poland. Recently I have started my first FPGA design. I want to make a relay card controlled by USB from a PC host. I have found on opencores a free IP core of USB 1.1 writen by Rudolf Usselmann, but as I have added it to my project in Xilinx ISE 8.2i and made from it a schematic element, the result was bigger, than whole schematic sheet and had many inputs and outputs. I would like to use some easyier IP core, that would have only 2 inputs (USBDP and USBDM) and 12 outputs (8 bit parallel data outputs and 4 controll lines), like a FT245R (http://www.ftdichip.com/Documents/DataSheets/DS_FT245R_v105.pdf page 5). Could you help me in my design? I would be very pleased, because I do not know enybody good in FPGA and my colleagues know less than me. Best regards.
