The data objects in VHDL and Verilog form expression operands. Knowing the operand differences between the two HDLs helps you write more efficient chip-design code. Expressions consist of operators ...

The repo contains the VHDL code and some C++ code that interfaces with the board and displays the results. If you have that particular board, it would be a good basis for a different project.

The VHDL code provided with this article (“VHDL Code Listing” at www.electronicdesign.com, Drill Deeper 19222) is an example of one way to implement the LED driver in a CPLD.

VHDL code looks odd from a software programmer’s perspective because it’s closer to the hardware and strongly typed: an 8-bit integer isn’t the same as eight wires in VHDL.
