Capgemini Engineering Design & Verification Engineer Interview Questions and Answers

Q1. What are storage class
Ans. 
Storage classes in C specify the scope and lifetime of variables.
• Storage classes include auto, register, static, and extern.

• Auto variables are local to a block 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 in one file and can be used in another file.

Q1. What is binary coded decimal?
Ans. 
Binary Coded Decimal (BCD) is a way of representing decimal numbers using a binary code.
• BCD uses four bits to represent each decimal digit.

• Each decimal digit is represented by its binary equivalent.

• For example, the decimal number 25 is represented in BCD as 0010 0101.

Q2. How keyboard mapping works in a microcontroller?
Ans. 
Keyboard mapping in a microcontroller involves assigning specific key codes to each key on the keyboard.
• Keyboard mapping is typically done using a lookup table that maps physical key presses to corresponding key codes.

• The microcontroller reads the key code when a key is pressed and sends it to the computer for processing.

• Keyboards may use different mapping standards such as ASCII or HID.

• Custom keyboard mappings can als...read more

Q2. Bit arbitration and its significance
Ans. 
Bit arbitration is the process of resolving conflicts when multiple devices try to access the same bus simultaneously.
• Bit arbitration is important in multi-master systems where multiple devices can initiate data transfer.

• It ensures that only one device gains control of the bus at a time.

• Different arbitration schemes include priority-based, round-robin, and collision detection.

• For example, in a CAN bus system, the devic...read more

Q4. Why can bus uses 120 ohm resistance
Ans. 
120 ohm resistance is used in CAN bus to match the characteristic impedance of the transmission line.
• CAN bus is a differential signaling system that requires a balanced impedance to prevent signal reflections.

• The 120 ohm resistance matches the characteristic impedance of the transmission line, which is typically 120 ohms.

• Without the proper impedance matching, signal reflections can cause data errors and reduce the maxi...read more
