the Universal Verification Methodology (UVM)

Preface

The Universal Verification Methodology (UVM) was announced by Accellera on December 23rd, 2009 and

introduced to the user community

May 17,2010. After long technical debates in Accellera, UVM was born

through a script that converted the

Open Verification Methodology (OVM) prefixes into UVM prefixes.

While some enhancements were added

2000, Verisity Design (now Cadence Design Systems, Inc.) introduced a collection

was

useful, generic library code could

automation and reuse.

reset solutions, scoreboard examples, and much more. This core functionality would define the scope

and

the verification methodologies used today, especially OVM. Later, the

ieRM

was enhanced with

module-to-system reuse, system verification components, software verification components, and the first

commercial register package,

ad.

In response,

in 2003, Synopsys announced the Reuse Verification Methodology library (RVM) for the Vera

verification language.

a result, many users looked at

RVM

as a subset

eRM.

RVM's

main contribution to the verification

user

community was the callback solution, which was borrowed from software design patterns, customized

for functional verification challenges, and which helped

add

procedural extensions to Vera

and

other

object-oriented languages that lacked the aspect-oriented capabilities

Over time,

RVM

was converted to

the System Verilog (

SV) Verification Methodology Manual (VMM) and was the Synopsys proprietary library

that

supported the evolving System Verilog standard.

The Advanced Verification Methodology (AVM) from Mentor was introduced in

2006.

The

technical

capabilities

this library mainly leveraged the OSCI SystemC Transaction-Level Methodology (TLM)

standard, leaving open higher-level verification needs such as test classes, complex stimuli generation,

configuration, extension via a factory,

and

more. While not a very high-level methodology,

AVM

was

important, since it was the first open-source verification solution.

Cadence' acquired Verisity in 2005,

and

began developing a

version

eRM.

While many verification

concepts mapped to

System Verilog in a natural

way,

some required modifications and enhancements to what

was available in other existing methodologies. The Universal Reuse Methodology (URM) was introduced in

early

2007. In addition to being open source and using TLM communications, URM brought many

the

proven capabilities

the eRM into the

community. Proven solutions such as the

eRM

architecture

and

packaging guidelines, sequences, and others were migrated into the System Verilog URM. In addition,

new

solutions such as an abstract factory, configuration mechanism, test classes, class automation (copy, print,

compare, an so on)

and

others provided a significant upgrade for SystemVerilog users.

January 2008, Cadence

and

Mentor joined forces to release OVM. The fact that URM and

AVM

were

already using TLM as the standard inter-component communication mechanism made the library

unifications relatively smooth. Because

URM has uniquely provided high-level methodology infrastructure,

was a logical choice to adopt the majority

that high-level methodology from URM into OVM. OVM's

primary

advantage over URM was that it was the first multi-vendor verification solution tested against more

than

a single vendor simulator. Given

the

early stages

the System Verilog language standard, the differing

language implementation order between the simulators and the lack

clarity on some

the constructs, this

was important to many users who wanted to keep their testbench vendor-neutral.

The

collaborative OVM proved to be a very good solution. Not only did it provide an open-source library,

examples,

and

documentation, it also set up a user community site,

www.ovmworld.org,

where OVM users

could share ideas, ask questions

and

make their own contributions

the methodology. As a result, many

companies chose

OVM as

the

verification methodology for their teams. Cadence also extended OVM for

integration

multi-language testbenches using

SystemVerilog and System

This was relatively easy since

the abstract concepts

OVM were originated from eRM.

Here

are in 2010:

The

OVM 2.1.1 was chosen

ofUVM

has begun. No more long technical comparisons between OVM

and

VMM are needed. No more obstacles for
