You will need a signal to bypass the value to the port in these cases. Difference between VHDL port mode out and Verilog output. Quote: > Is a Verilog output the same as a VHDL > port with mode out or a port with mode buffer. Actually, neither. In Verilog, port direction is just an indication, not a restriction and all pins are really inout due to net collapsing.

Port Modes: An in port can be read but not updated within the module, carrying information into the module. (An in port cannot appear on the left hand side of a signal assignment A module is a self-contained unit of VHDL code. Modules communicate with the outside world through the entity. Port map is the part of the module instantiation where you declare which local signals the module’s inputs and outputs shall be connected to. Inside entity, input-output pins of a circuit are declared using keyword PORT PORT (means interfacing pins) are declared with port_name, port_mode, and port_type port_name – it’s a user-defined name of the input-output pin port_mode – there are four types of port mode IN, OUT, INOUT and BUFFER. VHDL Port Map is the Process of mapping the input/ Output Ports of Component in Main Module.

You have good answers already for older tools - but if you use some tool which supports VHDL-2008, you are allowed to read output ports directly. You may need to enable this with a command line option. If your tools don't support it, whinge at the supplier until they do!

VHDL allows buffer port mode when a signal is used both internally, and as an output port when there is only one internal driver. Buffer ports are a potential source of errors during synthesis, and complicate validation of post-synthesis results through simulation. reference: Chapter 5, Xilinx Vivado Synthesis Guide

connecting port of mode OUT with port of mode BUFFER. 10. Emacs VHDL editing mode (vhdl-mode.el version 2.74) 11. Emacs VHDL editing mode (vhdl-mode.el version 2.71) 12. Emacs VHDL editing mode (vhdl-mode.el version 2.56.1.1) In VHDL, you can define an entity with ports and it translates to a block design with the port being either it’s input or output. You can use the port signals to drive other signals, however you can’t drive them inside a process.
