The Art of Verification’s Post

𝐇𝐞𝐲 𝐭𝐡𝐞𝐫𝐞, 𝐀𝐒𝐈𝐂 𝐕𝐞𝐫𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐞𝐧𝐭𝐡𝐮𝐬𝐢𝐚𝐬𝐭𝐬! Ever wondered about the 𝐬𝐞𝐜𝐫𝐞𝐭 𝐬𝐚𝐮𝐜𝐞 that makes your 𝐒𝐲𝐬𝐭𝐞𝐦𝐕𝐞𝐫𝐢𝐥𝐨𝐠 𝐜𝐨𝐝𝐞 𝐦𝐨𝐫𝐞 𝐞𝐟𝐟𝐢𝐜𝐢𝐞𝐧𝐭? Let’s spill the beans today! . ... ..... ....... .......... ............. Imagine you’re at a party. There’s a bulletin board where everyone can see the total number of guests. That’s what 𝐒𝐓𝐀𝐓𝐈𝐂 𝐩𝐫𝐨𝐩𝐞𝐫𝐭𝐢𝐞𝐬 in SystemVerilog are like! They’re shared across all instances of a class. So, if you have a Car class and a 𝐒𝐓𝐀𝐓𝐈𝐂 𝐩𝐫𝐨𝐩𝐞𝐫𝐭𝐲 totalCars, every time a new Car zooms in, totalCars goes up! But wait, there’s more! 𝐒𝐓𝐀𝐓𝐈𝐂 𝐦𝐞𝐭𝐡𝐨𝐝𝐬 are the unsung heroes of our code. They’re like the utility knife in your toolbox, always ready to help, no instance needed. They’re related to the class, but they don’t need to access any non-STATIC properties. Pretty cool, right? And here’s the cherry on top: In a UVM environment, 𝐒𝐓𝐀𝐓𝐈𝐂 𝐩𝐫𝐨𝐩𝐞𝐫𝐭𝐢𝐞𝐬 𝐚𝐧𝐝 𝐦𝐞𝐭𝐡𝐨𝐝𝐬 can supercharge your verification environment. Intrigued? Dive into my latest blog post for a deep dive into the world of STATIC in SystemVerilog. Let’s keep the conversation going and learn together in this thrilling journey of ASIC Verification! #theartofverification #ASICVerification #SystemVerilog #STATIC #UVM #VerificationEngineer https://lnkd.in/g_FWKFPs

I’m thrilled to share an update on my FIFO verification project! I’ve transitioned from a basic SystemVerilog testbench to a more structured UVM-based approach, making the verification process more scalable and efficient. Project Highlights: UVM Migration: Refactored the testbench using UVM components, improving modularity and enabling code reuse. Transaction-Level Modeling (TLM): Applied TLM for efficient communication between components. Key UVM Classes: Sequence Item & Class: Defined randomized FIFO transactions, with constraints ensuring realistic scenarios. The main sequence randomized 10,000 operations to stress-test the design. Driver & Monitor: The driver applied the sequence inputs to the FIFO interface, and the monitor captured output data, passing it to the scoreboard and coverage via TLM ports. Scoreboard: Compared the FIFO’s output against a golden reference model and flagged mismatches. Coverage: Multiple covergroups tested edge cases and state transitions (e.g., full, empty, almost full). Code Structure: Top Module: Instantiated the FIFO design, interface, and UVM components. The configuration object enabled flexible connections between the testbench and DUT. Agent: Managed the driver, monitor, and sequencer, orchestrating stimulus and data collection. Assertions & Coverage: Wrote immediate and concurrent assertions for key conditions like underflow, full, and empty. Functional coverage ensured testing of all relevant input-output combinations. Achievements: 100% Code & Functional Coverage: Every design path was covered through a combination of random and directed tests. Fixed Critical Bugs: Discovered and resolved five key bugs, including handling of underflow and the almost full signal. Testbench Efficiency: UVM modularization improved debugging, test reuse, and overall testbench organization, streamlining the verification process. I want to thank Eng.

Understanding the Difference: always @ (posedge(clk)) vs always_ff @ (posedge(clk)) in SystemVerilog In SystemVerilog, both always @ (posedge(clk)) and always_ff @ (posedge(clk)) define sequential logic triggered by the clock's rising edge. However, they serve different purposes: 1.always @ (posedge(clk)) (Traditional Verilog) This is the traditional way to define sequential logic in Verilog, offering more flexibility as it can model both sequential and combinational logic. It’s ideal for legacy code or when you need more general control over the execution flow, but it requires caution to avoid mixing blocking (=) and non-blocking (<=) assignments. 2. always_ff @ (posedge(clk)) (SystemVerilog) A SystemVerilog-specific construct, always_ff is designed for pure flip-flop-based sequential logic. It enforces clean code by only allowing non-blocking assignments (<=) and improving synthesis optimizations. This makes it clearer and more robust for hardware design, reducing errors like mixed combinational and sequential logic. Key Differences: *Flexibility: always @ (posedge(clk)) can handle both sequential and combinational logic, while always_ff @ (posedge(clk)) is strictly for sequential logic. *Syntax Safety: always_ff enforces the use of non-blocking assignments, preventing common mistakes, whereas always @ allows both types, leading to potential errors if not handled carefully. *Tooling & Debugging: Synthesis tools better optimize always_ff blocks and catch errors early, making it the preferred choice for pure sequential logic. In summary, use always_ff for clocked sequential logic to improve code clarity and reduce errors, while always @ remains useful for more flexible, non-standard logic needs. #systemverilog #verilogprogramming #SOC #FPGA
