module, a basic building design unit in Verilog HDL, is a keyword to declare the module’s name. module NAND2 (output Y, input A, B) We start by declaring the module. The code for the NAND gate would be as follows. Your one and only solution to your FLASING NEEDS…ġ- Whether it is NAND, NOR or any other kind of non-volatile memory - just solder, plug in and operate!ģ- Beside software-side updates, you can also expect hardware updates powered by customer requests!Ĥ- With a broad range of applications, such as EEPROM programming (among others: Altera, Lattice FPGA/ CPLD), Bad flash recovery, more commonly known as " Unbricking" (Modems, video cards, cell phones, music players) and plain serial programming (manufacture of your own device).ĥ- Supported devices include, but are not limited to: K9F1G08, S29GL128, K8Q2815, HY27US08.Ħ- Industrial programmers often range in the EUR 1000+ range with limited customer support. Verilog code for NAND gate using gate-level modeling. If you want a solderless clip with it, we have them for sale as well! Here is some great information on using the Progkseet: Progskeet# ProgSkeet_Tutorials if (A = 1'b1 & B = 1'b1) states that if both A and B are 1, then Y has to be 0, else 1.Use the coupon code progskeet and get 50% off of shipping! The condition for the NAND gate is that if both the inputs are high, then the output is low, else in every other condition that has to be high. * means that the code itself figures out the sensitivity list. We could also have written the always block as always * instead of always A). An advantage of using a always block is that it gets triggered only if any of the input from sensitivity varies. In Verilog, begin embarks and end concludes any block which contains more than one statement in it. It contains the input signals on which the statements of the block depends.
The always statement, a procedural statement in Verilog, runs the program sequentially. The reg data object holds its value from one procedural assignment statement to the next and means it holds its value over simulation data cycles. When our level of abstraction is behavioral, then we use the reg datatype in the output ports.
In this case, the port list includes the output and input ports.
module NAND_2_behavioral (output reg Y, input A, B) Verilog code for NAND gate using behavioral modelingĪgain, we begin by declaring module, setting up identifier as NAND_2_behavioral, and the port list. Simply by minimization, (or you may arrive by k-maps), we can state that: A B Y(A n and B) 0 0 1 0 1 1 1 0 1 1 1 0 Equation from the truth table
