The New Xilinx Real-PCI Solution for
Spartan-II FPGAs
|
|
The Spartan-II family delivers 100,000 system gates for under $10 and supports 32-bit
PCI up to 66 MHz speeds, giving customers design flexibility that's hard to beat.
And these low-powered, 2.5V devices feature 3.3V and 5V PCI compliant I/Os. Spartan-II
devices also feature multiple Delay Lock Loops (DLLs), on-chip RAM (block and distributed),
and the versatility of SelectI/O technology supporting over 16 high-performance interface
standards. All this in a chip that offers unlimited programmability, and can even
be upgraded in the field. The new LogiCORETM
PCI products guarantee timing for 33 MHz PCI and can be implemented in a wide range
of Spartan-II devices. In addition, 66 MHz, 32-bit PCI solutions are available from
Xilinx PCI XPERTs partners. The PCI pinout in selected packages is compatible between
various device sizes to allow customers to select the most cost-effective solution
for a specific application and migrate from one device to another without having
to re-layout the boards. |

Customer Benefits
|
|
In addition to PCI and glue custom logic, Spartan-II integrates and replaces numerous
different system functions such as HSTL translators, PLL/DLL clock management devices,
back plane logic and drivers, SSTL-3 translators and memory, all resulting in savings
in cost and board space. Combined with the Xilinx Real-PCI core, it represents a
significant opportunity for replacing many ASSPs that are currently used for PCI
applications. For example, a typical PCI ASSP design requires additional PLDs for
value added logic, which can all be integrated with the PCI interface in a single
Xilinx Spartan-II FPGA. |
|
By integrating the Xilinx fully-compliant Real-PCI core with the FIFO
Reference Design, value-added custom logic and the available system
features in one Spartan-II FPGA, designers can cut the cost significantly
when compared to PCI Application Specific Standard Products (ASSPs)
. As a result, designers of high-volume fully-compliant PCI applications
such as PC add-in boards, networking products, modems, and CompactPCI
boards can benefit from the flexibility of an FPGA and at the same
time reduce cost, time-to-market and board area. |
|
The Real-PCI from Xilinx is the only PCI
solution for programmable logic that guarantees the strict and challenging
PCI timing, including setup, hold, minimum and maximum clock-to-out
timing. This is accomplished by applying the unique Xilinx Smart-IPTM technology that
ensures consistent timing independently of FPGA device size, the surrounding
user logic, and EDA tools. |

"The Xilinx PCI Core has the most flexibility and complete feature set of
any vendor offering a programmable PCI core that we extensively evaluated. We were
most impressed with the silicon features, as well as a smooth migration path across
various cores and device densities", said Joel Van Doren, a senior digital
design engineer at Xerox Engineering Systems. "If our system performance
requirements change, we have every confidence that we can import a new core to the
existing design with minimal engineering effort".
Xerox Engineering Systems, a market leader for wide format Xenographic plotter,
copier and ink-jet equipment, chose the Xilinx PCI solution for a PCI-to-local bus
bridge device. |

XPERTS Design Services
In addition to the PCI intellectual property products, Xilinx offers PCI consultant
services through its XPERTS partners. These third-party specialists are trained on
Xilinx PCI solution and provide design services such as core integration and speed
optimization. When buying the PCI products from Insight in the US, 3-5 days of free
design services are included with the license.

|
|
PCI Training
To further complete the Xilinx PCI solution, Xilinx offers a three-day
PCI course for customers who are planning to design PCI systems. The
course will give an introduction to the PCI standard, cover configuration
and integration of core, system integration, verification and debug.

Licensing & Availability
The Real-PCI LogiCORE design is available for Spartan-II devices. Several Spartan-II
devices are available today. See product datasheet in Additional
Information section for specific devices and packages.

As part of Xilinx Silicon Xpresso initiative, all LogiCORE PCI design files are
distributed over the Internet and are available in the Xilinx PCI Lounge, a password
protected area on this website.
LogiCORE PCI V3.0, Configuration
and Download (Demo Version)
The download procedure couldn't be simpler:
- Configure the core in the intuitive, menu driven graphical user interface
- Click on download, and the tool will generate an EDIF netlist, simulation models
and instantiation code in VHDL and Verilog, and all the implementation constraints
required to guarantee the timing of the core design.
