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...
1. The D Flip-Flop ) Look for the datasheet of the 7474 D flip-flop and wire it on the breadboard making sure to supply 5V to both Preset and Clear. Utilize the function generator to provide a Clock signal of 1 Hz: i) Press AMPL and set value to 5 Vpp ii) Press FREQ and set value to 1 Hz ili) Press OFFSET and set value to 2.5 V This Clock signal will be the same for all circuits in...

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...
1. a) Complete the waveform templates for the Master –Slave D-flip-flop below with given D, CLK, CLEAR, and PRESET signals. Neglect the propagation delays. b) Does it have positive or negative edge triggering with respect to CLK? c) Are the asynchronous PRESET and CLEAR active-high or active-low? 2. Enabling of data load in the D-flip-flop was implemented with a 2-to-1 multiplexer as show below. The D-flip-flop has the positive edge triggering and the active-low asynchronous clear. a) Is the Enable...

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,...
10.21 Write a behavioral Verilog module vrDnegEc for a negative-edge-triggered D flip-flop with enable and asynchronous active-low clear. Also write a test bench that instantiates your flip-flop and exercises its operation for a comprehensive input sequence.
please give the verilog code and explain in the form of comments. Part I Consider the circuit in Figure 1. It is a 4-bit synchronous counter (text Section 5.9.2) that uses four T-type flip- flops (text Section 5.5). The counter increments its value on each positive edge of the clock if the Enable signal is asserted. The counter is reset to 0 by setting the Clear b signal low - it is an active-low asynchronous clear. You are to implement...
Consider the circuit in Figure 1. It is a 4-bit (QQ2Q3) synchronous counter which uses four T-type flip-flops. The counter increases its value on each positive edge of the clock if the Enable signal is asserted. The counter is reset to 0 by setting the Clear signal low. You are to implement an 8-bit counter of this type Enable T Q Clock Clear Figure 1. 4-bit synchronous counter (but you need to implement 8-bit counter in this lab) Specific notes:...
