Qbit Labs Fpga Design Engineer Interview Questions and Answers

To make an AND gate using NAND gates, connect two NAND gates in series.

• Connect the outputs of two NAND gates together

• Connect the inputs of the two NAND gates to the same inputs

• The final output will be the AND of the two inputs

HOLD time is the minimum time data must be stable before the clock edge, while SETTLING time is the time required for the output to stabilize after a change in input.

• HOLD time ensures that data is stable before the clock edge to prevent setup time violations.

• SETTLING time is the time taken for the output to settle to its final value after a change in input.

• Both HOLD and SETTLING times are critical for ensuring proper o...read more
