were legal VHDL, they would evaluation to either TRUE or FALSE whereas you are trying to see whether counter is within a certain range. (ie counter is whatever type it is, whereas an expression line that would evaluate to a boolean). In this video, we are discussing about "How to write a program for XNOR Gate using with select statement in VHDL". These statements are very useful in VHDL p VHDL Basics •VHDL –Selection •with-select •Choose a value when a certain situation exists with decision_signal select result_signal <= -- exhaustive list result_value when decision_value, result_value when decision_value, result_value when decision_value, result_value when decision_value; Limitation: Only one result signal VHDL 2 – Combinational Logic Circuits Reference: Roth/John Text: Chapter 2. Combinational logic with S select. y <= a when “00”, b when “01”, As a result, in theory, the “with/select” statement may have better performance in terms of the delay and area (see RTL Hardware Design Using VHDL: Coding for Efficiency, Portability, and Scalability, Xilinx HDL Coding Hints, and Guide to HDL Coding Styles for Synthesis). •with-select VHDL Basics 0000 0001 0101 0101 0000 0000 0110 0110 0000 0000 0111 1000 0000 0001 1000 0000 0101 0110 1000 0000 Mux3 Mux0 i_C = 0000 i_C = 1111 o_V i_C The VHDL syntax includes a method for or-ing different values to select a single branch.

The most common use for the with select statement is to a create a multiplexer, or MUX. The with is in reference to a select signal, which then determines the selection of the output signal, as the input options are then laid out given specific selects. I usually never come across a with select statement.
