I've also had bad luck with FIFOs. I eventually gave up and switched to a scheme that uses BRAMs instead. I'm using snap blocks to readout data from the design i'm currently working on. >I believe the error originates at the output line: >ERROR FROM TCL (opb_asyncfifo_simulink2ppc) This is over my head, but there must be someone on this list who knows more about yellow blocks. >I am missing the xilinx core license for ethernetlite and am not able >to compile anything with the LWIP block in place. Are the FIFO >errors related to this? Seems unlikely, but it's possible. Can you cut-and-paste the errors that you're getting? Billy
