PD Engineer Interview Questions and Answers

CDC stands for Clock Domain Crossing. Clock gating and power gating are techniques used to reduce power consumption in digital circuits.

• CDC refers to the process of transferring data between two clock domains with different frequencies or phases.

• Clock gating involves selectively disabling the clock signal to certain parts of a circuit when they are not in use, reducing power consumption.

• Power gating involves completely shutting off power supply to unused parts of a circuit, f...read more

Masks are prepared by designing the layout on a computer, transferring the design onto a mask plate, and using photolithography to etch the pattern onto the mask.

• Design the layout of the mask on a computer using specialized software.

• Transfer the design onto a mask plate using a process like electron beam lithography.

• Use photolithography to etch the pattern onto the mask plate.

• Inspect and test the mask for accuracy and quality before use in semiconductor manufacturing.
