General Description
2 General Description
2.1 Introduction
The PCI Express Extender is a extender for x1 link PCI express bus with integrated logic to
support debugging and verification of PCI express cards (referred as UUT, Units-Under-Test).
The UUT is plugged-in to the motherboard slot through the extender.
The extender uses a bus switch to connect/disconnect the UUT PCI express card from the
motherboard without shutting down the system. This flexibility minimizes the testing time and
protects the motherboard from damage such as overcurrent
The extender supports two ways of feeding the secondary PCI express bus with power: internally,
through the motherboard PCI express slot (+3.3V and +12V), and from an external power supply.
The external power supply has to provide +5V and +12V voltages to satisfy all PCI express
needs:
+12V and 3.3V
The extender fully protects your UUT and host system from damage by monitoring and limiting
the voltage and current.
The extender includes logic (based on the Xilinx CPLD XC9536XL-10) for debugging and
verification purposes:
•FPGA ByteBlaster functionality for the different types of the FPGA (like
Xilinx, Altera, Atmel, Lattice) through the external cable
•Master I2C and SPI interfaces
The CPLD logic can be customized as required. The standard package of the extender includes
full schematics and logic for the CPLD.
All these functions communicate with the computer through a parallel interface. The same
interface can be used to update or to load the customer’s specific functions into the on- board
CPLD.
The extender supports two types of the computer enclosures: the 2U and the standard profiles.
The angled connector of the extender allows for easy access to the UUT card.
The Extender has additional support tabs for the stabilization of the PCI express add-in card
(UUT). Amfeltec Corporation filed a Patent Application that covers this unique future.

Installation
5 Installation
5.1 Hardware Installation
•To install the PCI express extender power off the host computer. The shipped package
includes two types of brackets: low and high profile. If you like to change the brackets, you
need to unscrew the installed bracket from the connector J3 and replace by another bracket.
•The Extender is a universal solution for debugging different types of PCI express devices. In
order to properly configure the extender, please refer to Table 4.
•The extender has integrated Universal ByteBlaster. If you are going to use ByteBlaster,
please refer to Table 3 or Appendix B (switch SW2) to set the correct mode of operation.
•Select power source for UUT. The extender provides two options for selecting proper power
source: internal power from the primary PCI bus and external power supply. In order to
select the power source, refer to Table 4 .
•Install the extender into a PCI express slot. Extender can be installed in any PCI express
connector (1x/4x/8x/16x links). Important Note: Secure the extender using a screw in the
metal bracket!
•Install UUT board into extender.
•In case you are using external power supply you have to turn it on first (before powering up
the computer). Then, set switch SW1 to position ON (enable power) for secondary PCI bus
and UUT.
Now, you can power-up the host computer.
BE SURE THAT THREE GREEN LEDS (D2, D3 and D4) ARE ON!
In case led D1 is red, please turn off your computer and check the extender configuration jumpers
or UUT device for power shortage.
5.2 Software Installation
For normal operation, you don’t need to install additional software. But if are going to use HOT-
SWAP functionality, you need to install eX10Suite Software Suite (refer to ex10Suite Software
Manual for more details).

Hot-Swap Support
6 Hot-Swap Support
Perform hot swapping with a certain degree of carefulness. Remember that PCI configuration
won’t be loaded or automatically updated on insertion of a new UUT device unless you use the
supplied HOT SWAP software to reload the UUT’s PCI configuration.
6.1 Remove UUT Device
The following steps describe detail sequence for removing UUT device:
1. Save UUT PCI configuration into a file (refer to Software Manual for more details).
2. Unload all device drivers associated with the UUT.
3. Set the switch SW1 to “OFF” (disable power).
4. Now, you can remove UUT device from the secondary PCI Express connector.
6.2 Install UUT Device
The following steps describe details sequence for installing UUT device back to the system:
1. Plug in UUT device into the secondary PCI express connector.
2. Set the switch SW1 to “ON” (enable power).
3. Restore PCI configuration for the UUT device.
4. Now, the UUT device is ready for use.
