Microchip Technology interview question

1st two interviewers : Volatile v/s Non Volatile memory (RAM/ROM) Basic Verilog questions like blocking v/s non-blocking, continuous vs procedural etc Explanation of all my FPGA/Verilog-related projects 2:1 MUX using basic gates Setup vs Hold, which is more important, why is it caused. metastability - how to fix it FIFO uses ASIC design flow How does synthesis happen Synchronisation vs Asynchronous clock 3rd Interviewer: Equation for power in a resistor Analysis of parallel LC circuit 2 i/p AND gate where each input is getting pwm of period 10. But on input B, an inverter of 1ms delay is attached. What's the resulting waveform? Is it practical to be used with a f/f Transfer characteristic of NOT gate Can NOT gate be used as an amplifier
