Do I really need a commercial simulator?
A quick view of the benefits of a commercial simulator

As an Applications Engineer I visit lots of potential customers, or talk to them at trade shows, who are doing FPGA designs but don’t own a commercial simulator. I ask them why that is. Most of the time it is budgetary restrictions. They don’t...

Understanding the inner workings of UVM - Part 3
UVM Basics Part 3 of 3

In this blog, I am going to discuss different phases that UVM follows.   The reason why UVM came up with such phases is because synchronization among all design-testbench was necessary. Using Verilog and VHDL,...

SystemVerilog Functional Coverage in a Nutshell
Use native SystemVerilog constructs as metrics for verification closure in Riviera-PRO

Let’s say you have a block you need to verify. How do you know that the stimulus you are about to use is exhaustive enough and that you have covered the necessary scenarios/situations to prove it is working correctly?...

Understanding the inner workings of UVM - Part 2
UVM Basics Part 2 of 3

In this blog, my major focus is on explaining the concepts such as Sequence, Sequencer, Driver and showing how the communication takes place from sequence to sequencer and from sequencer to driver. In the previous blog, I included...

Plots: A New Way To Analyze Data

Data analysis is often a very time consuming process for a hardware design or verification engineer. We always end up using the waveform viewer which may not be very efficient in giving us a high-level overview of what we’re looking for. Data that is spread across...

Emulation in FPGA

For many years, emulators were available only to verification teams working on the largest projects in companies with deep enough pockets. Due to size rather than capabilities they were called “Big Box” emulators and typically were used in order to recover...

Code Coverage in HDL Editor? Now That’s a Nice Feature.

For a long time I have been a fan of code coverage tools that are embedded into the simulators themselves, and which give you the ability to switch easily between the code and the coverage results. It is particularly helpful to have a way...
