Building the FPGA bitstream file requires proprietary tools, but all the simulation can be done with just the Free Software - Icarus Verilog and GTKWave. Should I use IOBUF primitive or ODDR2 primitive? I'm pretty sure that "set_property IOB TRUE" is for requesting the placer to sticking flip-flops in the IOB and is not for requesting an IOBUF primitive to be used. Functional Categories I/O Components DesignElement Description IBUF Primitive:InputBuffer IBUFDS Primitive:DifferentialSignalingInputBufferwithOptionalDelay I have a question regarding Xilinx Vivado.

I wish we will be able to do a full P8X32A simulation before the end of this month ! When the tristate buffer output is "Z" you can read from the inout port, when the buffer is driving the line, it acts as an output. The ALT_IOBUF primitive allows you to do the following: Make an on-chip termination (OCT) assignment to a bidirectional pin from a lower-level entity.

The problem with using the Xilinx primitives (if you don't need them) is that it renders your logic specific to a Xilinx device, so if you ever switch to either a Lattice, Intel, or an ASIC design flow, or even an open source simulator, you'd need to start over with a new set of primitives.
