Q1. What is EM and how we mitigate it
Ans. 
EM stands for electromagnetic interference, and it can be mitigated through shielding, grounding, filtering, and proper layout design.
• Shielding: Using materials like conductive foils or metal enclosures to block EM waves.

• Grounding: Connecting electronic components to a common ground to reduce interference.

• Filtering: Using capacitors and inductors to filter out unwanted frequencies.

• Proper layout design: Keeping sensitiv...read more

Q2. What is race condition and stuck at zero fault
Ans. 
Race condition is a situation in which the output of a program depends on the sequence or timing of uncontrollable events. Stuck at zero fault is a fault in digital circuits where a signal line is stuck at logic zero.
• Race condition occurs when multiple processes access and manipulate shared data concurrently without proper synchronization.

• Stuck at zero fault is a common fault in digital circuits where a signal line is ...read more

Q1. Nonblock vs blocking difference with an example
Ans. 
Nonblocking operations allow the program to continue executing other tasks while waiting for a response, while blocking operations halt the program until a response is received.
• Nonblocking operations allow for asynchronous communication, while blocking operations are synchronous.

• Nonblocking operations are typically used in event-driven programming, while blocking operations are common in traditional procedural programm...read more

Q2. DFF Vs latch difference
Ans. 
DFF stores data based on clock signal, while latch stores data based on enable signal.
• DFF stands for Data Flip-Flop, while latch is a level-sensitive storage element.

• DFF stores data on the rising or falling edge of the clock signal, while latch stores data when the enable signal is high.

• DFF has two stable states (0 or 1), while latch has only one stable state.

• Example: D flip-flop, T flip-flop are examples of DFF, while
