could anyone pleas enlighten me, how to implement/design this project?? I use three register to store the three trials, but I don't know how to use counter to count the trialscandidates are allowed 3 trials, and in each trial, they are given SCORES on a scale of 0-3. The candidate qualifies the test if he gets SCOREs of 3 at least once OR, at least a 2 at least two times OR, at least a 1 in all three trials.
the SCRORE are set on a 2-DIP switch and a TRIAL pushbutton is pressed to prompt the system to read the SCORE for that trial. After reading in the SCOREs for all the 3 trials, the system shows the result (PASS/FAIL using green and red LEDs) for exactly 3 clock cycles, following which the system gets ready for the next candidate. As soon as a candidate qualify (for example if the candidate scores 3 in the first trial, he is declared qualified immediately) the next candidate can undergo the test.
