Hi, I have download the USB1_funct IP from http://www.opencores.org/projects.cgi/web/usb1_funct/overview and tried to download it on Spartan 3E but I have Error Map I looked at the Map Report and I got this : Number of bonded IOBs: 306 out of 232 131% (OVERMAPPED) and this Error : ERROR:Pack:18 - The design is too large for the given device and package. Please check the Design Summary section to see which resource requirement for your design exceeds the resources available in the device. Can anyone help how to fix it -- View this message in context: http://www.nabble.com/usb1_funct-Map-Error-tf3988331.html#a11324378 Sent from the OpenCores - USB mailing list archive at Nabble.com.
