you don't always need the tri-state bus.

the tri-state bus is needed mostly when you want to share pins with cfi flash or sdram.

eg, smc91111.

it is easier to build the component without avalon tri-state bus, and make your io port data bus tri-state with logic.

eg, lcd or many others on de2 board.

hi

be carefull with "inout" use inside an FPGA, it&#39;s easier to use to bus one "in" and the other "out" and multiplexe them.

for I/O pins there is no problem to use "inout", but with an internal signal ... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif
