Draw the circuit base on the coding provided
Screening: Setup and Hold time violations Synthesis constraints (ideal path, false path) Open page and closed page policy DDR project in-depth Panel round: Round 1 Asynchronous FIFO: How to design and problems faced? Synchronous FIFO verilog code Round 2 What is a glitch? When can it occur? Explain with waveforms. How to resolve the problem of glitches? How to design glitch-free circuits Static and dynamic power, Ways to reduce both Given a list in Python Sort it without using sort() Setup and hold time constraints Round 3 Resume projects and experience Open page vs closed page policy What is pipelining Adding pipeline registers to the timing path: It’s impact on performance and area Round 4 Verilog code for a given problem: given x config(7), y config(6) Convert into corresponding x and y coordinates and trace the path (Can be done using fsm for tracing both x and y coordinates) Round 5 Verilog coding (Question related to rotating bits for a given number) Most challenging problem faced Round 6 Verilog arbiter code (3 requests), can store outstanding requests in fifo
What is setup time and hold time? How would you fix these violations pre-silicon and post-silicon? What is the difference between clock skew, clock jitter, and clock uncertainty? Draw CMOS for a 1-input NOT gate, 2-input NOR gate, and 4-input NAND gate. Draw the circuit for a full-adder with minimal number of gates.
