Q2. Difference between d ram and s ram
Ans. 
DRAM is volatile memory that stores data temporarily, while SRAM is faster and more expensive but retains data as long as power is supplied.
• DRAM stands for Dynamic Random Access Memory, while SRAM stands for Static Random Access Memory.

• DRAM requires refreshing to retain data, while SRAM does not.

• DRAM is slower and less expensive than SRAM.

• Examples of DRAM include DDR3 and DDR4, while examples of SRAM include L1, L2, an

Q1. Testcase for software and hardware
Ans. 
Testcases for software and hardware
• For software: unit testing, integration testing, system testing, acceptance testing

• For hardware: functional testing, performance testing, stress testing, environmental testing

• Testcases should cover all possible scenarios and edge cases

• Testcases should be repeatable and automated where possible

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
