i was asked about the basic concepts about digital system. for example i was asked about a net with capciotos and inductors and about the output voltage based on the input voltage. in addition i was asked about FSM one question

Tell me about Setup and Hold Timing constraints, introduce a project you made in Lab course, implement XOR using NANDs, they also explained about the chip design process in their company, and that it is a fabless company. Static Timing Analysis was the main issue, power consumption, CMOS design and verification
