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 ...

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 ...

Last time, in the third installment of VHDL we discussed logic gates and Adders. Let’s move on to some basic VHDL structure. All HDL languages bridge what for many feels like a strange brew of ...

Editor’s Note: In this series of articles based on his book – Design Recipes for FPGAs – Peter Wilson provides a basic quick overview of VHDL (VHSIC hardware description language) followed by ...

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 ...
