Move up to the top left and click on “File” and select “New”. Open Multisim and you should see the default blank canvas for designing and simulating analog circuits.
#MULTISIM BREAD BOARD VIEW FULL#
Let's start with the full adder circuit from the previous step. Well, more like draw a picture, but you get the idea. And with Multisim, this is all that is needed to program the board. We are clearly building a logic circuit, and if visually describing the structure of the circuit isn't a structural method of coding, I don't know what you would consider should qualify. What do I mean? Here's the same full adder circuit as before, but this time with images of the logic gates used: Since Multisim is a circuit design program, we will be “writing” our code by utilizing the structural design method. Exactly how and what it compiles is beyond the scope of this document, but suffice it to say that both examples will result in pretty much the same program file. The compiler again works its magic and compiles a file that the chip can understand. In this example, we have explicitly told the compiler exactly how we want the input data to be logically processed. wire w01 = A ^ B wire w02 = Cin & w01 wire w03 = A & B assign S = w01 ^ Cin assign Cout = w02 | w03 endmodule Now imagine a large project with 100s of // lines of code to decipher. Without deciphering // the logic, it would be difficult at best to know what exactly is going on // just by glancing at the code. ) // Here we see the use of several logic gate structures. Verilog example of a structural design module Full_Adder_structural ( input A, input B, input Cin, output S, output Cout Here is the same full adder, but described structurally: In contrast, structural design is an explicit description of the exact logic required to process the input data correctly. The S and Cout bits are assigned to the respective bits in 'sum'. The compiler understands what “+” means and builds a binary adder to perform the task. When you add three bits, the largest value you can get is decimal 3, or binary 11, so we need the 'sum' value as a placeholder for the summed bits. assign sum = A + B + Cin assign S = sum assign Cout = sum endmodule Note the absence of any logic declarations like "AND" or "&". We've described the behavior of // the circuit. All three terms are added // together, so we must have an adder. ) wire sum // The next line makes it clear what we have. Verilog example of a behavioral design module Full_Adder_behavioral ( input A, input B, input Cin, output S, output Cout Here is an example of a two-bit full adder with carry-in:
In a behavioral design, you simply tell the compiler what you want to do and it will work it's magic in the background and compile the code in a way that the chip can understand it. You can even use both methods in the same project if you wish with no issues.

These methods are not language specific, but are instead conceptual methods of thinking of how to write the code. Within most of these HDL languages there are two different schools of thought used to write the code for the project, structural or behavioral. A Word About "Writing" the "Code" for FPGAsĬode for FPGA chips is written in one of several hardware description languages, with the two most common and prolific being VHDL or Verilog. Now that all of the correct programs and associated files are installed, let's get to programming some logic.Ģ. Follow the onscreen prompts to complete the install.

This will install Digilent Adept, if needed. Once the install is complete, be sure to restart your computer.Īfter restarting, navigate to “C:\NIFPGA\programs\Vivado2019_1\data\xicom\cable_drivers\nt64\digilent” on your hard drive and run the “install_digilent.exe” file. Get some popcorn, watch a movie, take a nap, grow some roses, etc.
