10.21 Write a behavioral Verilog module vrDnegEc for a negative-edge-triggered D flip-flop with enable and asynchronous...
Problem 1. a) Write a behavioral model of J-K flip-flop with active-low asynchronous reset. b) Write a proper test-bench and stimulus, thoroughly test your J-K-FlipFlop. Also, show your waveform and describe why your JK-FF does what is is designed to do. Problem 2. a) Write a Verilog module that will assert its output if a 4-bit input binary word is even. b) Show the waveform for two input patterns “1100” and “0101”

Write the verilog code that implements a negitive edge D-Flip Flop with asynchronous active low preset and clear I have : module dff( preset, clear, clk, D, Q) input preset; input clear; input clk; input D; output Q; reg Q; always @ (negedge clk or negedge preset or negedge clear); if (preset); Q = 0; else (clear == 0); Q = D; endmodule I honestly just want to know if i'm doing this right or not, if im not correct,...
5.4 2um 4-34. Design a negative-edge-triggered flip-flop. The flip flop has three inputs; these are Data, Clock, and Enable. If, at the negative edge of the clock, the enable input equals to 0, then the state at Data input is stored in the flip-flop. If, at the negative edge of clock, Enable is in 1 state, then the current stored value in the flip-flop is held. Design the flip-flop using only SR latches, AND gates, and NOT gates. 4-34. Design...
3. Answer the following questions about a data flip-flop (D-Flip Flop): a) (4 ps) Write the VHDL required to define a rising-edge triggered (RET) D-Flip Flop with additional clock enable (CEN) and reset inputs. Your reset may be synchronous or asynchronous. Assume any input, output, or signal variables that you require have already been declared in VHDL (you do not have to write the declarations for these) b) [I pal ls your reset syachronous or asynchronous for the D-Flip Flop...
Use the Quartus Prime Text Editor to implement a behavioral model of the D flip-flop described above in a file named d_flops.sv. Specify the D flip-flop’s module according to the interface specification given in the table below. Port Mode Data Type Size Description RST in logic 1-bit Active high asynchronous reset CLK in logic 1-bit Synchronizing clock signal EN in logic 1-bit Synchronous clock enable D in logic 1-bit Synchronous data input Q out logic 1-bit Current/present state Qbar out...

Verilog! NOT VHDL Please (4 pts) Write a behavioral Verilog module to implement a counter that counts in the following sequence: 000, 010, 100, 110, 001, 011, 101, 111, (repeat) 000, etc. Use a ROM and D flip-flops. Create a test bench for your counter design and run functional simulation in ModelSim.
