System verilog UVM interview questions - Part 1

Praxisnahes Kursprojekt

Class Project: Build a UVM Testbench for a Simple DUT and Document Key Interview Concepts

Project Overview:

In this class project, you’ll apply the knowledge gained throughout the interview question series by building a complete UVM testbench for a simple DUT (Design Under Test), such as a 4-bit ALU or a UART transmitter. The goal is to demonstrate your understanding of UVM components and architecture while practicing interview-level coding and documentation skills.

⸻

Project Objectives:
• Design a basic DUT (provided or your own).
• Create a UVM testbench using the UVM base classes: uvm_test, uvm_env, uvm_agent, uvm_driver, uvm_monitor, uvm_sequencer, and uvm_sequence.
• Configure and connect the testbench using the UVM configuration database and TLM communication.
• Use the UVM factory and objection mechanisms effectively.
• Document key interview concepts and code snippets with explanations.

⸻

Instructions:
1. Choose or Use Provided DUT:
• Use the provided 4-bit ALU RTL code or create a small DUT (e.g., counter, UART TX).
2. Create the UVM Components:
• Write UVM components (env, agent, driver, etc.) based on the DUT interface.
• Use transactions (sequence_item) and sequences to drive stimulus.
3. Implement a UVM Test:
• Write at least one test case that covers different scenarios of your DUT.
• Use UVM reports and objections to manage simulation flow.
4. Document Your Work:
• Include inline comments and markdown (.md or .pdf) explaining key UVM interview concepts you applied (e.g., “Why use the factory?”, “How TLM ports work”).
• Provide a brief summary explaining how your testbench is structured.
5. Submit Your Project:
• Upload your complete testbench files (SV/RTL), documentation, and a screenshot or waveform image of your simulation results to the Class Project Gallery.
• Review at least one peer project and provide constructive feedback based on UVM coding style, structure, or clarity.

⸻

Deliverables:
• RTL and testbench code (.sv)
• Readme or documentation file (markdown or PDF)
• Simulation waveform screenshot or transcript
• Optional: short video walkthrough (2–3 mins) explaining your architecture

⸻

Skills You’ll Practice:
• UVM component hierarchy
• Sequence and TLM communication
• Configuration and factory usage
• Writing clear, interview-ready code and explanations
