Q2. Metastability - how do we fix it ?
Ans. 
Metastability occurs when a flip-flop samples an input signal at an unstable time, leading to unpredictable output. It can be fixed by using synchronization techniques.
• Use multiple stages of flip-flops to reduce the probability of metastability

• Increase the setup and hold times of flip-flops to provide more time for the input signal to stabilize

• Use synchronization circuits like 2-flop synchronizers to ensure proper samp

Q3. OCV AOCV variation, multiple buffers in a path - how does it affect ?
Ans. 
OCV AOCV variation with multiple buffers in a path can affect timing and power consumption.
• OCV (On-Chip Variation) and AOCV (Advanced OCV) variations can cause timing delays in a path with multiple buffers.

• The variation in buffer sizes and types can lead to different delays in the path, impacting overall timing.

• AOCV takes into account the statistical variations in process parameters, providing a more accurate estimatio...read more
