VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to define ...

VHDL is all about creating logic. As a descriptive language, all the HDL languages bring something unique to programming – making true parallel logic circuit. As we take baby steps into VHDL, we will ...

So far we have been looking at the more basic structure of VHDL and using combinational logic circuits. In this article, however, we will look at how to use and interface clock signals, the beating ...

As can be seen from the VHDL, we have defined a specific 16 bit bus inthis example, and while this is generally fine for processor design with afixed architecture, sometimes it is useful to have a ...
