Verification Interview Questions

3,718 verification interview questions shared by candidates

In round 1 - 19 MCQs related to general concepts, a mix of digital and analog electronics, mainly digital. 3 subjective question from - STA, STA, FIFO depth calculation 2 circuit design questions - FSM sequence generator , differently clock delayed output using MUX and flip flops. Round 2- Started with basic STA questions and went up to solving some on paper. Later digital design questions about mux , flip flop, counter, clock divider , FSM. Basic Verilog code like Fibonacci numbers generator , counter. MOS - MOS inverter questions and sub threshold region conduction. Short channel effects.
