Spring break is approaching, but who has time for the beach? You'd rather be spending time with us at DVClub!

This month we'll have two excellent presentations from local DV engineers Nihar Shah from ARM, and Prasad Saravu from Samsung. Nihar will be explaining to us how to "Detoxify" your schedule with a low-fat UVM environment (yummy!), while Prasad will be discussion his group's use of a multi-processor memory scoreboard on a recent project. In addition to the lunchtime presentations, please stick around for an informative tutorial by Breker CEO Adnan Hamid. Adnan is an industry expert in portable stimulus, which was by far the hottest topic at the last DVCon, you won't want to miss it.

As always, this is a free catered lunch with plenty of opportunity to learn about what's going on in the local verification community. Come catch up with old friends and colleagues, meet new friends, and network with others in the industry. Special thanks once again to our DVClub Sponsors for making this event possible.

This will be another awesome event, we look forward to seeing you there.

Title: Detoxify Your Schedule With A Low-Fat UVM Environment

It has been widely accepted that a test environment must be portable from unit-level to higher levels of integration. Reasons cited for this range from higher verification quality to increased verification efficiency. However, the development cost in making things portable is often taken for granted, and the decision to port is often done without an honest cost/benefit analysis. Porting a unit environment to a higher level is not always the most practical way to find new bugs, increase coverage, or otherwise improve the overall quality of verification. 

This presentation proposes the use of self-checking stimulus using UVM sequences as an alternative checking methodology to traditional UVM scoreboarding.  The methodology proposed can significantly reduce the development time spent on building and maintaining verification infrastructure.  The presentation also discusses the benefits and risks of self-checking stimulus and how to address the risks, including non-portability of the results checkers from unit to full-chip.

About Nihar:

Nihar Shah has spent 16 years in design verification, especially coding and architecting testbenches using UVM and SystemVerilog.  In the past he has worked at Intel and Marvell on application processors for cell phones.  Most recently he was part of the Project RAPID team at Oracle Labs, and has just started a new position at ARM.  Given the rising complexity of designs, he is determined to find more efficient ways of achieving high-quality verification in shorter times.

Multi-Processor Memory Scoreboard: A multi-processor memory ordering and data consistency checker

In this presentation a verification architecture called Multi-Processor Memory Scoreboard (also referred as MPMS, the checker, the scoreboard) developed at Samsung Austin Research & Development Center is described. This is a RTL simulation based scoreboard which performs data consistency and memory ordering checks as required by ARMv8 ISA memory model and finds RTL errors very close to the failure point. Along with the knowledge of architectural memory ordering requirements, the scoreboard employs age-order and time-order relations of instructions of the test programs and performs data consistency and memory ordering checks.

About Prasad:

Have 11+ years of CPU verification experience. Currently working in SARC (Samsung Austin R&D Center) since Oct 2012 on CPU verification. Before that I was working in Nvidia on CPU verification as well. Most of my verification experience is focused on memory ordering and consistency, coherency and MP verification with leading stimulus, checker and testbench developments.

Detoxify Your Schedule With A Low-Fat UVM Environment



"Portable Stimulus with Breker’s TrekSoC tool" by Adnan Hamid, CEO, Breker Verification Systems  

Portable Stimulus is the next big thing in Functional Verification! In this tutorial we will look at creating self-checking models that capture verification intent. These models can be run under UVM at the unit level and sub-system level and using Software Driven Verification (C test cases) at the full chip level in simulation, emulation or post silicon. We will look at debug, coverage and coverage closure in each environment.
