Q1. Explain storage variables in C?
Ans. 
Storage variables in C are used to store data temporarily during program execution.
• Storage variables in C are declared using data types like int, float, char, etc.

• They can be stored in different memory locations like stack, heap, or data segment.

• Variables declared outside functions have global scope and are stored in data segment.

• Variables declared inside functions have local scope and are stored in stack memory.

Q3. First three kinds of sorting
Ans. 
The first three kinds of sorting are bubble sort, selection sort, and insertion sort.
• Bubble sort compares adjacent elements and swaps them if they are in the wrong order.

• Selection sort selects the smallest element and swaps it with the first element, then selects the second smallest element and swaps it with the second element, and so on.

• Insertion sort builds the final sorted array one item at a time by inserting each

Q1. What is the functional coverage ?
Ans. 
Functional coverage is a metric used to measure how much of the design functionality has been exercised by the verification environment.
• Functional coverage is used to ensure that all the features of the design have been tested.

• It is a measure of how much of the design functionality has been exercised by the verification environment.

• Functional coverage is typically defined in terms of coverage points, which are specific...read more

Q2. What is randomisation
Ans. 
Randomisation is a technique used in verification to generate random test cases.
• Randomisation is used to increase the probability of finding bugs in a design.

• It involves generating random inputs to test the functionality of a design.

• Randomisation can be used in both simulation and formal verification.

• It helps in identifying corner cases and edge cases that may not be covered by directed tests.

• Randomisation can be contr...read more

Q1. CDC technique , and why need of CDC
Ans. 
CDC stands for Clock Domain Crossing technique used in digital design to ensure proper data transfer between different clock domains.
• CDC technique involves synchronizing data signals when crossing between different clock domains to prevent metastability issues.

• It is necessary because different clock domains operate at different frequencies and can lead to data corruption if not properly synchronized.

• Common CDC techniqu...read more

Q2. How to transfer multiple bits in CDC
Ans. 
Transfer multiple bits in CDC involves using a parallel data transfer method.
• Use parallel data transfer method to transfer multiple bits simultaneously

• Implement a shift register to store and shift out multiple bits

• Utilize multiplexers to select and transfer specific bits

• Consider using a bus architecture for efficient data transfer
