Q1. What are storage classes in c language?
Ans. 
Storage classes in C language define the scope and lifetime of variables.
• There are four storage classes in C: auto, register, static, and extern.

• Auto variables are local to the block they are declared in and have automatic storage duration.

• Register variables are stored in CPU registers for faster access.

• Static variables retain their value between function calls.

• Extern variables are declared outside of any function and ...read more

Q2. How many address lines are present in 1kb memory?
Ans. 
There are 10 address lines present in 1kb memory.
• 1kb memory = 1024 bytes

• To address 1024 bytes, 10 address lines are needed (2^10 = 1024)

Q1. Describe the PD flow
Ans. 
The PD flow is the process of designing the physical layout of integrated circuits.
• Initial floorplanning to determine the placement of blocks and macros

• Placement and optimization of standard cells

• Routing of interconnects to connect the various components

• Physical verification to ensure design rules are met

• Timing closure to meet performance targets

Q2. How to fix setup and hold violation
Ans. 
Setup and hold violations can be fixed by adjusting timing constraints, optimizing clock tree, and redesigning critical paths.
• Adjust timing constraints to allow more time for signals to propagate

• Optimize clock tree to reduce clock skew and improve timing

• Redesign critical paths by adding buffers or restructuring logic

• Use ECO (Engineering Change Order) to make necessary changes without redoing the entire design

Q5. Why does setup and hold ail on same path
Ans. 
Setup and hold time violations can occur on the same path due to different reasons.
• Timing violations can occur due to variations in process, voltage, and temperature (PVT)

• Clock skew between different paths can lead to setup and hold violations on the same path

• Issues with clock tree synthesis or routing can also contribute to setup and hold time violations

• Improper constraints or incorrect timing analysis setup can resul

Q1. Explain operation of rc circuit
Ans. 
An RC circuit consists of a resistor and a capacitor connected in series or parallel, used for filtering, timing, and signal processing.
• RC circuit operation is based on the charging and discharging of the capacitor through the resistor.

• When a voltage is applied to the circuit, the capacitor charges up to the applied voltage through the resistor.

• The time constant (RC) determines how quickly the capacitor charges or disc...read more

Q2. Draw waveform for diode
Ans. 
A diode waveform typically shows a voltage drop when forward biased and no current flow when reverse biased.
• Forward biased: voltage drop across diode, current flows

• Reverse biased: no current flow, diode acts as open circuit
