Let's Program the Transistors
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…
1. Explain the concept of sensitivity lists in Verilog. A sensitivity list specifies the signals that trigger the execution of an always block when they change. Example: Here, the block executes whenever a or b changes. 2. What is the purpose of generate statements in Verilog? The generate statement is used to dynamically create repetitive hardware structures or conditional instantiations during elaboration. Example: 3. Discuss…

1. Explain the difference between blocking and non-blocking assignments. Example: 2. What is the difference between posedge and negedge? Example: 3. What is the purpose of the assign statement? The assign statement is used for continuous assignments in combinational logic. It is used to drive values to wire data types. Example: 4. How do you declare a parameter in Verilog? A parameter is…

1. What is Verilog and why is it used in VLSI design? Verilog is a Hardware Description Language (HDL) widely used to design and model digital electronic systems. It helps in writing structured, reusable code to describe how a circuit should function. Verilog is crucial in VLSI design because it supports simulation, verification, and hardware…

Micromax Informatics Interview Question Bank continued from Part 1… Q : Which among BJT and MOSFET has higher gain and why? A : The current in BJT is exponentially dependent on input whereas in MOSFET, it is square law. So, trans-conductance of BJT is higher than that of MOSFET and thus BJT has higher gain than…
