Turnkey Verification of Router FPGAs and Boards |
|
|
Leveraging Patni's verification expertise, a small startup router company saved over $75,000 in EDA license
and infrastructure costs.
The Challenge
Our customer is a small, aggressive startup designing its first router product. The
router includes content awareness and rich QOS features, resulting in several
large boards each contain a mixture of complex FPGAs, programmable processors,
and other large off-the-shelf components. The customer had an aggressive
schedule for system development, with a fixed end date governed by
demonstration at an interoperability show in order to close its first sale. Our
customer did not have verification engineers, an existing verification
methodology, or any verification tools, and they wanted to conserve venture
capital by not investing in these areas.
 |
The customer needed fast verification to allow tape-out of two complex boards and large FPGAs |
|
The customer needed enough verification to minimize lab bring-up and
software integration of the complete system |
|
The customer did not want to invest in verification engineers, tools, or
testbench development. |
The Solution
Patni's PREP Verification Methodology
|
Patni uses the existing and proven PREP verification environment to allow productive
verification work immediately |
|
Patni library of SVCs provides 4 of the 5 transactors (BFMs) needed for verification |
|
Patni FPGA verification methodology focuses on large datapaths, discrete functions, and
key configurations. FPGA and board pinout and floorplan are quickly confirmed, and critical
operation is efficiently verified at optimal cost |
|
Patni board verification methodology uses connectivity extracted from board schematics,
and simulates processor boot-up and device access to facilitate rapid lab integration at
minimal cost. |
Patni Outsourcing
|
Patni consultants are familiar with the functions and protocols and rapidly create the
testplan and begin verification |
|
Patni performs the verification as an outsource project, using EDA and compute
infrastructure in its Design Center |
|
Patni consultants install a regressable test suite at the client site and train the client to
support maintenance and ECOs of the boards. |
The Benefits
|
The turnkey outsource verification is completed on schedule, and the boards are built on time. The PREP verification environment and existing SVCs saved over 2
calendar months on the verification schedule relative to starting from scratch |
|
The verification results in no hardware bugs on the simulated boards and FPGAs. System integration proceeds on plan and the system is successfully demonstrated |
|
The turnkey outsource delivery saved the customer nearly $100,000 in EDA licenses and infrastructure, and
over $100,000 in salary cost relative to provisioning an inhouse verification team. The customer can now support
regressions of the design, without the salary cost of an ongoing verification team, and has saved over $200,000 in
carrying cost of the engineers between product releases. |
