When a customer wants a ROM programmed, they supply the manufacturer with a program, usually in the form of a truth table with addresses as the inputs, so that the manufacturer knows which connections to metalize between the decoder outputs and the OR gates. An example is shown below that uses a 1-hot decoder. A junction or dot shows a connection being made from a decoder output to the bus, which connects to the OR gate inputs. Can you verify that this circuit diagram would produce the truth table shown? Work through for your own understanding.

Task 3: Design of 4-to-1 line Data Selector / Multiplexers: A multiplexer (MUX) is a combinational circuit that selects binary information from one of many input lines and directs the information to a single output line. The selection of a particular input line is controlled by a set of input variables called selection inputs. Normally, there are 2n input lines and n selection inputs whose bit combinations determine which input is selected. 4-to-1 Do MUX y D, a) Complete the truth table of the 4-to-1 line multiplexer. SELECTION INPUT OUTPUT SO $1 Y 1 1 b) Draw the 4-to-1 multiplexer logic circuit.
Assume we are writing a testbench for a sequential circuit that has three control inputs (cA, cB, cC) and a periodic clock (clk). If we define CLK_PERIOD as a localparameter with a value of 50 (nsec), write the testbench segment that would ensure all possible combinations of the control inputs were tested on a clock rising edge. This is can be done more elegantly if you define each time step in terms of the constant CLK_PERIOD. Your answer should include the statements that define clk, cA, cB, and cC over time. Hint: think of how you would show all combinations of three variables on a truth table and replicate that over time, where each combination is held over a timespan with a clock triggering edge.
Connect the AVR ATMEGA 32 from Proteus to the Serial Port of the PC and a Switch to a pin on one of the PORTs. Write IN C the following program: If SW is pressed, released then pressed again (0, 1, 0 or 1, 0, 1 depending on your circuit), send "Hello" to the PC. If SW is pressed then released (0, 1 or 1, 0 depending on your circuit), send "Bye" to the PC. Modify and run the program in Activity 3 to transfer the data at the rate of 115200 bps (or the closest available to this value) Please be fast!
Draw a circuit to implement a switching network with two data inputs (A and B), two data outputs (C and D), and a control input (S). If S=1, the network is in pass-through mode: C=A and D=B. If S=0, the network is in crossing mode: C=B, and D=A. Use the most reasonable combinational building blocks or gates. Label the inputs and outputs.
Show how to modify the internal circuitry of the shift register in Figure 8 so that it will also shift to the left and right. Basically, you need to replace Sh and L with A and B, and let the register operate according to the table shown in Table 1. making sure this does not violate the honor code. this is not any homework or an exam, this is meant for learning, I need to understand this problem and how to get there

Implement a 4-bit counter that counts down, starting at fifteen and ending at zero. Also, implement a reset that allows you to place it in its initial value which would be 15. For this make use of FF JK and logic gates.

I believe this problem is from computer systems/architecture. PLEASE TRY YOUR BEST. I NEED TO UNDERSTAND THIS PROBLEM I need you to design a digital logic circuit as a read only memory (ROM) [Decoder + OR gates]. A ROM accepts a three–bit number (x2 x1 x0) and generates an output binary number equal to the input squared + 2. Here is the equation: A = x2 + 2, with input (x) : 0 ≤ (x) ≤ 7 (a) Try to set–up the truth–table [Binary inputs: (x); Binary outputs: ..., A2, A1, A0] (b) What is the size of the initial (unsimplified) ROM ? (c) What is the size of the final (simplified) ROM ?
Find a ready-made combined logic circuit description or write it yourself directly. The module should have at least 4 ports, and at least one port should be 8-bit. Then verify with UVM using this module as DUT (Design Under Test).SystemVerilog hardware description language should be used.
