Macnica Americas Accelerates PCI Express Simulation for Altera FPGAs with DrivExpress Version 1.0
SAN DIEGO --(Business Wire)--
Macnica Americas, Inc. today announced the release and immediate
availability of DrivExpress Version 1.0, offering a PCI (News - Alert) Express
verification suite designed for high performance simulation of PCI
Express-enabled designs that target Altera FPGAs.
Verison 1.0 adds a Python-based scripting interface, multi-lane support,
and a custom installer, not available in early versions of the tool
previously released to customers. The Python interface provides an
additional productivity advantage, as the scripts can be used as a
communications medium between software designers writing drivers and
engineers developing the FPGA.
Acceleration beyond conventional RTL-based models is achieved through
use of the Direct Programming Interface (DPI) available in most Verilog
simulators, which allows C++ code running natively on the host computer
to interact directly with the simulation.
"The useof PCI Express hard IP cores is becoming increasingly common on
today's FPGAs," said Marc Levy, Chief Technical Officer at Macnica
Americas. "However, this represents a verification problem for designers
because commercially available simulation tools target the more complex
task of protocol compliance, while vendor-supplied PCIe testbenches are
not flexible enough to adequately test user designs. DrivExpress fills
this gap with a cost effective, easy-to-use solution, specifically
targeting Altera (News - Alert) FPGA designs."
"One of the challenges with using PCI Express on FPGAs is that
every design is unique and thus requires a custom software driver," said
Jeremy Nightingale, Technical Marketing Manager at Macnica Americas.
"DrivExpress provides built-in functions that can be used to mimic
software driver behavior, so the scripts built with these functions can
be used as a starting point for software driver development as well as
for driver debug. These functions are so intuitive,
however, that even someone unfamiliar with Python should have no trouble
DrivExpress is available from Macnica Americas' website in three
licensed editions, including a zero-cost starter edition.
Macnica Americas offers IP, design services and distribution for Altera,
Aptina, Broadcom (News - Alert) and other semiconductor manufacturers across North
