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 ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device. ALU was ...

While it is tempting to write RTL and let the synthesis tool take over, this isn’t the best way to get the results we want. In this article, we’ll learn how to create complex combinatorial code in ...
