System Verification and Technology Transfer |
|
|
Patni's expertise in verification methodologies helped a leading technology company verify complex FPGA
designs ahead of schedule.
The Challenge
Our customer's high-density Network Access system is based on several large
FPGAs that are substantially more complex than their previous generation,
including programmable processors and spread across multiple boards. To meet
their aggressive schedule, our customer needed to verify the design and avoid a
lengthy lab debug and integration phase. Our customer's engineers were used to
designing with little simulation, and relied heavily on lab debug. Our customer did
not have an existing verification methodology to use, and they lacked the
experience, time and money needed to develop it by themselves.
 |
The customer could not afford the time and cost to ramp up and train engineers
in a verification intensive design flow, yet recognized that they needed this
capability long term |
|
The customer wanted to use its full time employees on the project to minimize
external spending |
|
The customer didn't want to incur the time and cost of ASIC respin(s). |
The Solution
Patni applies state-of-the-art verification methodology to the design flow
|
Defines test approach and configurations |
|
Writes the detailed test plans |
|
Project planning and scheduling
|
Patni's PREP Verification Methodology
|
Patni installs the existing and proven PREP verification environment at the customer's facility |
|
Patni library of SVCs provides 4 of the 9 transactors (BFMs) needed for verification |
Patni Consultants
|
Patni consultants develops new transactors for the customers proprietary and project-specific
busses and interfaces |
|
Patni consultants perform the initial verification |
Patni training
|
Patni conducts training sessions to teach the customer's engineers verification methodology,
the PREP environment, and the project-specific transactors and their use |
|
Patni consultants work side by side with the client engineers, who expand the initial
verification and implement the complete test suite. |
The Benefits
|
The system verification is finished on schedule |
|
The PREP verification environment is installed and in use by the customer 3 months sooner than if they created an environment from scratch. The environment is ready to
be used by the customer on future projects, and they have five proprietary transactors(BFMs) added to the offthe-shelf library |
|
The customer used its own engineers to perform the
verification, reducing by 80% the number of outside
resources and expense required |
|
The customers 10 engineers have been trained and
coached through a complete verification project. The
group has evolved to a leading edge verification
methodology and is ready to use this new core
competency on future projects. |
