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 ...

Hence, SystemC constructor can only be written once complete VHDL code has been parsed. This demands that the information for the SystemC constructor be gathered while parsing the VHDL module, ...

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.
