SEQUENCER The job of the sequencer is to control the flow of sequences to the driver. The fact that you can write six lines of code yet have a powerful implementation is the beauty of UVM. Having the sequencer mechanism prepared for you in the library allows you to build the testbench faster and more…
In earlier post i.e. https://theartofverification.com/uvm-testbench-architecture/ we learned which all components are required to develop UVM Environment/Testbench to verify complex Designs. In this blog post we will verify a small RTL Design by developing complete UVM Environment. Let’s start with the basic RTL Design and understand it’s specifications/working. Here as we can see that in the…
A typical UVM testbench contains several components. First, let’s look at a simple UVM testbench diagram. There are several components illustrated within this diagram with the most fundamental one being the agent. An agent is a container that holds all the needed components for a particular protocol. A typical UVM agent might contain a driver,…
I hope you started understanding assertions and their operators well with practical examples. Let’s start learning more operators in this post. Before starting part-2 of assertions operators and their basic examples if you haven’t visited part-1 of basic assertions operators and their examples I highly recommend that please visit that blog post and revise your…
System Verilog assertions always help to speed up the verification process and it’s very powerful and widely used in the ASIC verification. Identifying the right set of checkers in the verification plan and implementing them using effective SV assertions helps to quickly catch the design bugs and ultimately helps in high-quality design. With the ever-increasing…
1. What is the difference between code coverage and functional coverage? There are two types of coverage metrics commonly used in Functional Verification to measure the completeness and efficiency of verification process. 1) Code Coverage: Code coverage is a metric used to measure the degree to which the design code (HDL model) is tested by…
A verification Engineer is not just to write some test scenarios to verify something it’s way beyond that. A verification engineer’s focus after understanding specifications such as test planning, and strategy need to be applied to verify the complex design, and what needs to be implemented using which methodology. Verification engineers always emphasize why and…
If you’re looking to enter the world of ASIC or FPGA verification, then chances are you’ve heard of Universal Verification Methodology (UVM). UVM has become the industry standard for verifying digital designs, and as such, it is a crucial skill set for anyone looking to break into the field. Whether you’re a recent graduate or…
SystemVerilog is a hardware description and verification language that extends the capabilities of Verilog HDL. It is widely used in the semiconductor industry for the design and verification of digital circuits and systems. If you are preparing for a SystemVerilog interview, you may be asked a variety of questions related to the language, its features,…
Functional coverage and code coverage both are contributing highly on sign off criteria for verification. Implementers have to make sure that their test plan and test environment is intelligent enough to satisfy the code/functional coverage closure. Code coverage is generated by tool with the help of the simulations generated by the test environment. So test…
