Right, FPGAs don't really have internal tri-state (or wired-or) busses. If you had two I2C modules connected to the same pins, the I/O/T model allows you to combine them at one output. If the module just took 'SDA' and did the tri-stating internally then I would expect you to get that error when you connected another I2C module. -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
