Q1. STA numerical to calculate setup and hold time
Ans. 
Setup and hold time can be calculated using the formula: Setup time = (Clock period - Required time) and Hold time = (Required time)
• Setup time is the amount of time data must be stable before the clock edge

• Hold time is the amount of time data must be stable after the clock edge

• Setup time = Clock period - Required time

• Hold time = Required time
