The combinational logic is defined by a Boolean logic expression (refer to Chapter 5 for an introduction to digital logic techniques) made up of the basic logic gates (AND, OR, etc.) whose meanings in VHDL are shown in Table 6.2. The logic operators can be used as they are, or they ...
The combinational logic circuits can be implemented using logic operators and VHDL statements. The VHDL statements when and select are used for the implementation if conditional expressions are available in logic circuit implementation. The combinational circuits are implemented via concurrent codes....
This logic is unlikely to work and/or may become some kind of oscilator. The std_logic_vectors appear because the signed data type is really only a VHDL abstract construct. In reality you will only get 1's and 0s, so the VHO only gives you std_logic_vectors. It is functionally ...

Delay using logic to me is scary stuff. Anyway, for the VHDL Keep: You need this once (I put it just below my global signal declaration) ATTRIBUTE keep: boolean; And for each signal (where signal_s is your signal name): ATTRIBUTE keep of signal_s: SIGNAL is true; I w...

Sequential clock gating provides significant power savings because it not only switches off the clock going to registers but also the datapath logic in the fanout of gated registers. However, RTL synthesis tools are not capable of identifying sequential clock gating opportunities. Fortunately, recently...
