The update counter controls which of the four displays needs updating. The main counter provides a clock signal to both the update counter and the display counter. The figure below shows the three main sections of the PLD schematic. To create the PLD schematic double click the PLD sub-circuit and select Open subsheet from the properties window.

The PLD code needs to have two main functions: In this example we are creating a simple up-counter and the required logic to control the four 7 segment displays. The annotated figure below shows the required components for the simulation.Īfter completing the top level circuit we need to create the digital logic within the PLD schematic. From here we can create the components that feature on the Digilent board allowing us to simulate the schematic.
To achieve this we use a PLD sub-circuit. It places the PLD logic in place around the IO contained on the board. The top level schematic, as part of this project, allows for simulation. Getting Started with Digilent Boards in Multisim. More details on installing and targeting a range of Digilent boards from Multisim can be found here: Whilst this tutorial and the accompanying example were produced using the Digilent Nexys 3 the same could be achieved on other Digilent boards. This tutorial is going to provide an example of how students can develop counters using Digilent boards and use these to control the onboard 7 segment displays.
Using Multisim and the PLD schematic students can gain experience of using counters in hardware before the need to learn these more advanced descriptive languages. Typically, using traditional approaches this would require the student to learn advance Hardware Descriptive Languages such as VHDL and Verilog.

Gaining a comprehension of timing is difficult without using hardware because of the inability for software based simulations to meet the speed of those running in hardware. When moving beyond simple logic diagrams, timing soon becomes a critical part of digital design.

View the complete Teaching Digital Logic Fundamentals tutorial series In this set of tutorials we demonstrate how digital logic theory can be taught using educational hardware to provide a hands-on approach to learning. The PLD schematic allows educators and students to create graphical logic diagrams like those found in textbooks and deploy these to Digilent educational boards. Multisim Programmable Logic Diagram (PLD) along with support for leading Digilent teaching hardware allows students to put the fundamentals of digital theory into practice. Taking a hands-on approach to learning digital logic can be difficult without the need for students to learn complex hardware descriptive languages (eg.
