Bitsilica Asic Design Verification Engineer Interview Questions and Answers

Q1. Write code randc behaviour
Ans. 
randc behavior generates random complex numbers with specified distribution
• Use randc to generate random complex numbers

• Specify distribution using arguments like mean, variance, etc.

• Example: randc(10, 1, 2) generates 10 random complex numbers with mean 1 and variance 2

Q1. 1) Explain flipflops 2) UVM Architecture 3)constraints
Ans. 
Flip-flops are sequential logic circuits used to store and manipulate binary data.
• Flip-flops are basic building blocks of digital circuits.

• They can store a single bit of information, either 0 or 1.

• Flip-flops have two stable states: set and reset.

• They are used to store and transfer data in sequential circuits.

• Examples of flip-flops include D flip-flop, JK flip-flop, and T flip-flop.

Q2. Difference between Ff & latch
Ans. 
FF is edge-triggered, stores data on clock edge. Latch is level-sensitive, stores data as long as enable signal is active.
• FF stores data on clock edge, latch stores data as long as enable signal is active

• FF has two stable states (0 or 1), latch has one stable state (depends on enable signal)

• FF is used for sequential circuits, latch is used for level-sensitive circuits

• Example: D flip-flop (FF) vs SR latch

Q2. Swap the bits in a byte.
Ans. 
Swapping bits in a byte involves exchanging the positions of bits within an 8-bit binary number.
• A byte consists of 8 bits, indexed from 0 to 7.

• To swap bits, you can exchange pairs: (0, 7), (1, 6), (2, 5), (3, 4).

• Example: For byte 10110010, swapping gives 01011001.

• Use bitwise operations: AND, OR, and XOR to manipulate bits efficiently.

• In programming, you can use masks to isolate and swap bits.
