WebDec 12, 2015 · A port that is declared as input (output) but used as an output (input) or inout may be coerced to inout. If not coerced to inout, a warning has to be issued. In practice, everything ends up as an inout, and you may or may not get a warning. So, you can do pretty much anything in a simulator, but a linter or a synthesiser should pick up any ... WebProblem regarding inout port assignment. Hello there, I want to interface a chip with FPGA and it has 8 data pins (bidirectional). Some time to give command to the chip I need to write to these data lines and some times I need to read from these data lines, Hence I am defining these 8 data lines as "inout reg [7:0] Data" in my verilog code.

Therefore it is recommended to put all inout signals at the top-level (with the associated 'Z' driving logic), and use plain old in and out ports throughout your design. In fact, given an inout port "DataBus", I create signals "DataBus_in" and "DataBus_out". pinoy in croatia
