Multilinx
The new MultiLINX TM cable takes advantage of the USB port found on newer
PCs. MultiLINX delivers the ultimate in download performance: Up to 12
Mbits/second throughput. MultiLINX features an adjustable voltage interface
that enables it to talk to systems and I/Os operating at 5, 3.3, or 2.5
volts.
Software support for the MultiLINX cable is provided in version 2.1i
of the Alliance Series and Foundation Series software products.

Parallel Cable III (HW-JTAG-PC)
The Parallel Download cable is a PC-only based cable that attaches to the
parallel port of a designer's computer. The cable supports the following
families:
- XC4000XL/XV/EX/E
- Spartan & Spartan-XL
- XC5200
- XC9500 & XC9500XL
- Virtex & Virtex-E
Two rows of "flying wires" are shipped with the cable. They
are attached at the end of the cable to the designer's target system. XC9500
& XC9500XL devices use the "JTAG" row of wires. The FPGAs listed above
also have JTAG ports. Users can use the same "JTAG" connections if the
user inserts the JTAG symbol in their design.
Designs for FPGAs without the JTAG symbol inserted into their designs
can still use the "FPGA" row of wires for configuration of the FPGA.
XChecker Cable (HW-XCHCBL)
The XChecker Download and Readback Cable is supported on PC and workstation
platforms. The XChecker attaches to the host computer's RS232 serial port.
The cable supports downloading and JTAG on the following families:
- XC4000E/EX
- SPARTAN
- XC5200
- XC9500
A 3V adapter is available by ordering HW-XCH3V. With the addition
of this 3V adapter, the cable supports downloading and JTAG on the following
families:
- XC4000XL/XV
- SPARTAN XL
- XC9500XL
Designers can verify device operation by uploading information from
a configured FPGA and compare it to the original data that was downloaded.
An innovative feature of XChecker cable is the "read back" capability offered
for some of the devices supported. This capability is currently limited
to devices with densities smaller than the XC4013XL or devices requiring
less than 512Kbits of configuration data.
Internal logic nodes and signals can also be probed by taking a "snapshot"
of the FPGA and uploading the data via XChecker. XChecker can control a
user's system clock, allowing a design to be single-stepped and displayed
for each clock cycle.

Cable Software
The Parallel and XChecker cables are supported by both the Xilinx Foundation
and Alliance series development systems software packages. Although
a complete installation is not necessary to use the features of the cables,
the JTAG programmer software must be installed to use the Parallel cable
with the on-chip JTAG port. The Hardware Debugger software must be
installed in order to use the XChecker cable. The Hardware Debugger
software must also be installed to use the Parallel cable for FPGAs using
the FPGA download row of wires. |
