Physical Description
The Platform Cable USB electronics are housed in a
recyclable, fire-retardant plastic case
EMI shield attenuates internally generated emissions and
protects against susceptibility to radiated emissions.

Operation
This section describes how to connect and use Platform
Cable USB.
Minimum Host Computer Requirements
The host computer must contain a USB Host Controller with
one or more USB ports. The controller can reside on the PC
motherboard, or can be added using a PCI expansion card
or PCMCIA card.
Platform Cable USB is supported on systems that meet the
Xilinx ISE
go to:
and select the ISE tool of choice. Platform Cable USB is
designed to take full advantage of the bandwidth of USB 2.0
ports, but it is also backward-compatible with USB 1.1 ports.
Refer to
additional information on connection environments and
bandwidth.
Operating Power
Platform Cable USB is a bus-powered device that draws
less than 100 mA from the host USB port under all
operating conditions, automatically adapting to the
capabilities of the host USB port to achieve the highest
possible performance.
Platform Cable USB enumerates on any USB port type (for
example, USB ports on root hubs, external bus-powered

than 100 mA from the host USB port. The legacy DLC9 cable
model requires 230 mA to operate in USB 2.0 Hi-Speed mode or
150 mA to operate in USB 2.0/1.1 full-speed mode. Some older
root hubs or external bus-powered hubs might restrict devices to
100 mA. The legacy DLC9 cable model does not enumerate on
hubs with the 100 mA restriction.
Device Driver Installation
A proprietary device driver is required to use Platform Cable
USB. Xilinx ISE software releases and service packs
incorporate this device driver beginning with version 6.3.03i
for the Windows operating system or 7.1i for the Linux
operating system. Platform Cable USB is not recognized by
the operating system until an appropriate Xilinx ISE,
ChipScope™ Pro or Platform Studio (EDK) software
installation has been completed.
Refer to UG344, USB Cable Installation Guide, for a
complete guide to installation of the Platform Cable USB
and its device drivers.
Firmware Updates
Platform Cable USB is a RAM-based product. Application
code is downloaded each time the cable is detected by the
host operating system. USB protocol guarantees that the
code is successfully downloaded.
All files necessary for successful cable communication are
included with every Xilinx ISE software installation CD.
Revised application code is periodically distributed in
subsequent software releases. ISE Service Pack and
WebPACK™ releases can be downloaded from
www.xilinx.com. Project Navigator automatically checks for
new releases when an Internet connection is detected.
When Xilinx applications are invoked and a connection is
established with Platform Cable USB, version information for
several software components is displayed in a command log.
Platform Cable USB also contains an embedded in-circuit
programmable CPLD. Each time a Xilinx application is
invoked, the firmware version for the CPLD is examined.
The CPLD is automatically reprogrammed over the cable if
the firmware version is out of date (see
Although a rare event, when CPLD reprogramming is
necessary, the CPLD reprogramming process can take
considerable time and must not be interrupted once started.
The reprogramming time via a USB 2.0 port can typically
take 10 to 15 minutes. Reprogramming time varies
depending on the ISE software version, the type of USB
port, and the performance of the host system. Later
versions of the ISE software can reprogram CPLDs faster
than older versions.
The DLC9G and legacy DLC9LP cable models draw less
for an explanation of USB enumeration).
