Synaptics Interview Questions, Process, and Tips

Q1. What is the purpose of the P1500 when we already have the 1149.1 JTAG?
Ans. 
P1500 is used for testing at the core level while 1149.1 JTAG is used for testing at the board level.
• P1500 focuses on testing individual cores within an integrated circuit.

• 1149.1 JTAG is used for testing interconnections on a circuit board.

• P1500 allows for more detailed testing and analysis of core functionality.

• 1149.1 JTAG is more suitable for overall board testing and debugging.

• Both standards complement each other in
