This repository contains a collection of VHDL code samples showcasing various digital logic designs. It includes more advanced algorithms and components, such as a CORDIC function for efficient ...

These examples use Yosys + NextPnR with ghdl-yosys-plugin to synthesize VHDL into a bitstream. This can be loaded onto the OrangeCrab using its DFU bootloader. vhdl.blinky - Basic "hello world" type ...

Learn how to write, simulate, synthesize, debug, and learn VHDL code for your hardware circuits. Find out the basics and advanced topics of VHDL with examples and resources.

In this example, I used a very basic design of just a few components on a signal level. However, it’s easy, once you know how, to add as many layers as you want. Let’s look at the VHDL code first: At ...

The VHDL structures we will look at now will all be inside a VHDL structure called a ‘process.’ The best way to think of these is to think of them as small blocks of logic. They allow VHDL to break up ...

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 ...

FSM (Finite State Machine) by the name is defined as a state machine that has a finite number of states. The example for the states can be A, B, C ... Brace yourself let's learn how to implement the ...

Part I, "Circuit Design," examines in detail the background and coding techniques of VHDL, including code structure, data types, operators and attributes, concurrent and sequential statements and code ...

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.

This paper presents a novel tool flow combining rewriting logic with hardware synthesis. It enables the automated generation of synthesizable VHDL code from mathematical equations and the quick ...
