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.arrow_forwardAssume that an external clock signal is being fed into pin T0CKI (RA4). Write a C program touse Timer0 in 8-bit mode to count the pulses and display the state of the TMR0L count onPORTB. Start the count at 0x00 and stop the count at 0xFF+1. Use the MPLAB simulatorto verify the proper operation of the programarrow_forward

Using the asynchronous ripple counter in Figure 1 and assuming that the propagation delay from an input clock to a change in the output of Q is 9ns, what is the worst-case delay (i.e. longest delay) between an input clock pulse and the counter being in a final state. Give which state(s) of the counter have the worst-case delay.arrow_forwardProblem 5 Write the entire VHDL code for a 64-bit synchronous counter that has a synchronous reset and an asynchronous preset. The preset value is 2048 and the reset value is all 0's. The 4 MSBS of the counter output also feeds a 4-1 mux.
