Earlier this year, Cadence announced the expansion of its VIP
Catalog to include Accelerated VIP (AVIP). AVIP is used together
with Cadence's Verification Computing Platform to enable RTL verification. AVIP running on the Palladium XP platform
consistently executes hundreds of times
faster than with simulation. Obviously this is great news for validation
teams since designs routinely exceed 50Mgates these days and much greater
performance is needed.
AVIP is also proving to be uniquely suited for
another purpose: driver/firmware
integration and validation. Cadence is seeing strong demand from our
customers for this need.
One example I've been closely monitoring is Samsung Memory. I thought I'd draw your attention to it since
many of our customers could similarly benefit from this approach.
Samsung has been using Cadence AVIP to verify their new PCI
Express based solid-state drive (SSD) design.
Samsung SSDs are typically being employed in laptops and servers to
reduce power and space and increase reliability relative to traditional hard
A bit of
This year Samsung Memory added a PCI Express interface to their
SSD controller design. The PCI Express
design addition significantly increases transaction rates and reduce latencies
relative to earlier SSSD generations. To
verify the block level protocol compliance of the new interface they began by
using Cadence's simulation VIP. This proved
to be highly effective. However, when the
time came to do firmware/driver validation at the SoC level, they found the simulation
environment wasn't sufficiently fast. In
fact, Samsung determined they'd need a validation environment capable of delivering
hundreds of times greater performance.
When they turned to Cadence for suggestions we recommended using our PCI
Express Accelerated VIP (AVIP) with a C++ user interface designed for Palladium
XP simulation-acceleration. Since Samsung
had already used our PCI Express simulation VIP, the transition to AVIP was even
more straightforward than usual. Within
three weeks the accelerated environment was up and running. This in itself was highly advantageous since it
meant Samsung's driver developer/integrators would become productive much
sooner than if they'd had to wait for an FPGA prototype. It also enabled Samsung to realize validation
productivity gains of 100%. See the Samsung
Memory success story for additional details.
Samsung's experience, taken together with other customers has made
clear that driver/firmware validation is becoming crucial step in SoC level validation. In fact we are seeing rapidly increasing
demand for this use model.
Cadence AVIP optimizes Acceleration/Emulation to enable software
driven use models. Seeing this trend we are
already working on ways to make firmware/driver validation even easier and
faster. If you've got a project nearing
the SoC validation phase I'd urge you to connect with Cadence. We're confident that AVIP in conjunction with
our Palladium XP Verification Computing Platform and RTL simulation can help
you to improve productivity and quality in your projects.
