Preview: ... ABEL is less powerful than the other two languages and is less popular in industry. This tutorial deals with VHDL, as described by the IEEE standard 1076-1993. Although these languages look similar as conventional programming languages, there are some important differences. A hardware description language is inherently parallel, i.e. commands, which correspond to logic gates, are executed (computed) in parallel, as soon as a new input arrives. A HDL program mimics the behavior of a physical, usually digital, system. It also allows incorporation of timing specifications (gate delays) as well as to describe a system as an interconnection of different components. 2. Levels of representation and abstraction A digital system can be represented at different levels of abstraction [1]. This keeps the description and design of complex systems manageable. Figure 1 shows different levels of abstraction. Figure 1: Levels of abstraction: Behavioral, Structural and Physical The highest level of abstraction is the behavioral level that describes a system in terms of what it does (or how it behaves) rather than in terms of its components and interconnection between them. A behavioral description specifies the relationship between the input and output signals. This could be a Boolean expression or a more abstract description such as the Register Transfer or Algorithmic level. As an example, let us consider a simple circuit that warns car passengers when the door is open or the seatbelt is not used whenever the car key is inserted in the ignition lock At the behavioral level this could be expressed as, Warning = Ignition_on AND ( Door_open OR Seatbelt_off) The when keyword is optional and will execute the next statement when its condition evaluates to the Boolean value TRUE. Notice that the difference between the next and exit statement, is that the exit statement terminates the loop. f. Wait statement The wait statement will halt a process until an event occurs. There are several forms of the wait statement, wait until condition; wait for time expression; wait on signal; wait; The Xilinx Foundation Express has implemented only the first form of the wait statement. The syntax is as follows, wait until signal = value; wait until signal’event and signal = value; wait until not signal’stable and signal = value; The condition in the “wait until” statement must be TRUE for the process to resume. A few examples follow. wait until CLK=’1’; wait until CLK=’0’; wait until CLK’event and CLK=’1’; wait until not CLK’stable and CLK=’1’; For the first example the process will wait until a positive-going clock edge occurs, while for the second example, the process will wait until a negative-going clock edge arrives. The last two examples are equivalent to the first one (positive-edge or 0-1 transitions). The hardware implementation for these three statements will be identical. It should be noted that a process that contains a wait statement can not have a sensitivity list. If a process uses one or more wait statements, the Foundation Express synthesizer will use sequential logic. The results of the computations are stored in flip-flops. g. Null statement The null statement states that no action will occur. The syntax is as follows, null; It can be useful in a case statement where all choices must be covered, even if some of them can be ignored. As an example, consider a control signal CNTL in the range 0 to 31. When the value of CNTL is 3 or 15, the signals A and B will be xor-ed, otherwise nothing will occur. entity EX_WAIT is port ( CNTL: in integer range 0 to 31; A, B: in std ...
