VHDL does not allow you to "read" a signal that is declared as an output port. (Think hardware: why can't you do this in real hardware?) So the simple and correct solution is to declare an internal (to the entity's architecture) signal and use that signal as the target (left-hand-side) of the assignment.

direction) and the type of each port on the entity : entity HALFADD is port (A,B : in bit; SUM, CARRY : Each port has a mode that defines a direction: in, out, inout, or buffer. Modes in, out, and inout all have the obvious meanings. Ports declared to be of type out may not be read. Therefore, the assignment: c1 <= c0; would be illegal since c0 is declared to be an out port.

You may want to search for "status" in all code, to see if a "status" port with mode out is referenced for read. If so, the problem can be fixed in VHDL-2002 if an internal signal is driven by the component, and the internal signal then drives the out port. This internal signal may then be read internally. could anyone please tell me what linkage ports are for and how to use them?

From the VHDL-2002 Standard: a) For a formal port of mode in, the associated actual must be a port of mode in, inout, or buffer. b) For a formal port of mode out, the associated actual must be a port of mode out, inout, or buffer. c) For a formal port of mode inout, the associated actual must be a port of mode …

ACTION: Associate a single port or signal with the formal port, or change the formal port's mode to IN. This is a Most important question of gk exam. Question is : In VHDL, the mode of a port does not define: , Options is : 1. an input., 2. an output., 3.both an input and an output., 4. the TYPE of the bit., 5.

The dual port ram is generated using different write and read clock. In the VHDL code of multi-port RAM, the write and read clock are connected to the same input clock signal generating a single clock domain. Figure 4 reports the RTL-viewer of Altera Quartus II of the multi-port RAM VHDL implementation. All ports must have an identiﬁed mode. Allowable Modes: • IN Flow is into the entity (input only) • OUT Flow is out of the entity (output only) • INOUT Flow may be either in or out (either in or out) • BUFFER An OUTPUT that can be read from (mode: in) (mode: inout) ram_wr_n (mode: buffer) bobs_block state_0 (mode:out) clock data From the VHDL-2002 Standard: a) For a formal port of mode in, the associated actual must be a port of mode in, inout, or buffer.

This mode is different from inout mode. The source of buffer port can only be internal. In a VHDL Design File ( .vhd) at the specified location, you associated the specified actual port with the specified formal port. However, you cannot associate an actual port of the specified mode with a formal port of the specified mode. For example, you cannot associate an actual port of mode OUT with a formal port of mode IN. In a VHDL Design File at the specified location, you associated the specified formal port with an expression. However, the formal port has the specified mode, which is not IN. Only a formal port with mode IN can be associated with expressions. ACTION: Associate a single port or signal with the formal port, or change the formal port's mode to IN. Hello, I had a component in my VHDL design.
