2 BIT GRAY CODE COUNTER VERILOG CODE CODEThe Gray to Binary code converter is as shown in figure 7. The K – map for various binary outputs and the corresponding simplified expression are given below: Step2: Write K – ma for each binary output and get simplified expression The most common behavior for a reset scenario is depicted in the waveform below:īorder conditions handling, requires the counter to take a decision on the next value to transition to.The truth table of Gray code and its equivalent binary code is as shown in table: Sampling time: immediately after you perform a counter value check. If the system clock can vary within a given frequency range, but remains constant during simulation, then you should cover the minimum, maximum and middle values of the frequency range, regardless of the synchronous nature of the counter. The synchronicity aspect does not impact the proposed checks and coverage definitions. Draw the flip-flop circuit diagram, the state graph, the timing diagram, the truth table (with clk pulse) and. Regarding SynchronicityĪ counter is synchronous if all its flip-flops are connected to the system clock. Design a 5-bit binary counter using JK flip flops. (This is an implicit check that is passed if all other checks pass for a given set of clock frequencies.)Ĭoverage definitions are explained in more detail in the following sections. ![]()
