From AHG: The following warnings are normal: WARNING:Xst:1348 - Unit Reg8OD is merged (output interface has tristates) WARNING:Xst:1348 - Unit TSBuffer8 is merged (output interface has tristates) Tristate I/O often (or always) gives warnings using the Xilinx tools. If those are the only items he noticed then he might either need pull up resistors on any lines that need to be outputs or software help using the DataPort class. -- -- Bryan Armstrong bryan.armstrong-6tN4nzCoH/[email protected] _______________________________________________ TINI mailing list TINI-6tN4nzCoH/[email protected] To UNSUBSCRIBE, edit your profile, or see list archives: http://lists.dalsemi.com/mailman/listinfo/tini
