Hello,
This is obviously a beginner question, but I am getting some odd behavior from a tri-state mux, and was just wondering if someone could check the correctness of this code:
inout [7:0] bus;
wire bus_oe;
wire select;
wire [7:0] data1;
wire [7:0] data2;
assign bus = bus_oe ? (select ? data1:data2): 8'hZZ;
The behavior sought is: if 'bus_oe' is false then 'bus' is HiZ, otherwise if 'select' is true connect 'bus' to 'data1', if false connect 'bus' to 'data2'.
I am using Quartus II 10.0 with a cyclone II chip.
Thanks,
Wahran
