PROBLEM STATEMENT: For the third lab I was to implement VHDL code for the four attached diagrams shown below. For each of the four programs it was required that I use concurrent statements only. There were also different types of logic required for each of the four sets of code. For the comparator I was

VHDL Programming Processes . In VHDL Process a value is said to determine how we want to evaluate our signal. The signal is evaluated when a signal changes its state in sensitivity. 2020-12-17 · In programming languages, case (or switch) statements are used as a conditional statement in which a selection is made based on different values of a particular variable or expression. A general discussion of these statements can be found here. In hardware description languages (HDL) such as VHDL and (System)Verilog, case statements are also These statements are collectively known as sequential statements and can only be used within a process block.
