1. What is the difference between synthesis and simulation? 2. How to prevent race conditions in simulations? 3. Difference between ifdef and ifndef? Example of ifdef: Example of ifndef: ifdef and ifndef directives help control conditional compilation, enabling flexible and reusable code for different environments such as simulation, synthesis, debugging, or different target platforms. 4. What is…
1. Model a tri-state buffer in Verilog. 2. Implement a 2-to-1 multiplexer in Verilog using a continuous assignment. 3. Model a combinational circuit using case? 4. How do you model a flip-flop in Verilog? A flip-flop is edge sensitive. The following code represents a positive-edge-triggered D flip-flop that stores the value of d at each rising clock edge. 5. How…
Problem Statement: Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit. Pin Input / Output Description D Input Data Input CLK…

Combinational and Sequential circuits are the most essential concepts to be understood in digital electronics. Sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs. Combinational Logic Circuits Sequential Logic Circuits Output is a function of the…
