What is an always construct in verilog?
In Verilog, an always construct is a procedural block that defines a section of code that executes continuously based on specific sensitivity conditions. It is commonly used to model combinational and sequential logic. The always block can be triggered by changes in specified signals (for combinational logic) or clock edges (for sequential logic) and allows designers to describe the behavior of digital circuits in a clear and structured manner. The syntax typically includes sensitivity lists or edge triggers to specify when the block should execute.

What is a NMOS PLA?
NMOS PLA is a Programmable Logic Array which is designed by employing NMOS technology i.e. by employing nmos transistors to realize the required gates of PLA. PLA is a combination AND gates and OR gates to produced sum of products terms needed for realizing the required combinational logic. It consists of an array of AND gates followed by OR plane. the connections to the AND and OR inputs can be programmed based on our needs.
Design and draw a combinational circuit using AND-OR-NOT gates that accepts 4 input bits and produces two bit output the first of the two bits is set to 1 if the number of 1s in the input is even?
Design and draw a combinational circuit using AND-OR-NOT gates that accepts 4 input bits, and produces two bit output; the first of the two bits is set to 1 if the number of 1's in the input is even; and the second of the output bit is set to 1 if the input have 3 or more (all four) 1 bits.
Similarities between combinational logic circuit and sequential logic circuit?
both combinational and sequential circuits have two inputs and outputs..!
What are the steps in the design process of converting a set of design specifications into a functional combinational logic circuit?
A: FIRST step is form a flow chart. whereby decisions can be followed
How do you make a combinational circuit?
To create a combinational circuit, start by defining the desired logic function or truth table that specifies the relationship between input and output signals. Next, select appropriate logic gates (such as AND, OR, NOT) based on the function. Then, design the circuit layout by connecting the gates according to the logic diagram, ensuring that inputs are correctly routed to produce the desired outputs. Finally, simulate or implement the circuit to verify its functionality.
What is combinational circuits in computer architecture?
combinational circuit is depend only on inputs,like sequential circuits its not depend on previous outputs.
Why is Boolean algebra used for combinational logic circuits?
Because it is a very efficient language for describing their operation as well as a tool to assist in design optimization (reducing the cost of the circuit when built).
What are the 2 types of logic circuit for digital system?
combinational circuit and sequential circuit
What products use combinational logic?
A car buzzer, Google search engine, etc.
What are the use of And logic gate?
AND logic gate is used to obtain the product of two digits. It is used in various combinational and sequential circuits.
What is Combination logic circuit?
The combinational logic circuits are a type of logic circuits containing only logic gates (AND, OR, XOR, NOT, NAND, NOR) and its output only depends on the current input (do not have memory).
What are the division of logic gates?
Logic gates can be primarily divided into two categories: combinational logic gates and sequential logic gates. Combinational logic gates, such as AND, OR, and NOT gates, produce outputs based solely on the current inputs without memory. In contrast, sequential logic gates, like flip-flops and counters, consider both current inputs and past states, allowing for memory and timing functions in circuits. These divisions form the foundation for building complex digital systems.
What is meant by flip flops and latches?
Flip flop is a combinational logic circuit. It is defined as an one bit memory devise.
What is Lookup table in digital circuit?
A lookup table (LUT) in digital circuits is a memory device used to implement combinational logic functions. It stores predefined outputs for specific input combinations, allowing quick retrieval of results without needing complex logic gates. LUTs are commonly found in programmable logic devices like FPGAs, where they enable flexible design by allowing designers to customize logic functions easily. By using a LUT, designers can simplify circuit design and improve efficiency in implementing complex logic operations.
