We have designs where we needed more uarts, but didn't have any more room/ I/O pins on the virtex, so we have implemented an uartlite compatible interface in a S3E connected through a 16bit bus. Not exactly brilliant hw design, but it works and it keeps the sw support to a minimum. -- Bye, Peter Korsgaard
