FEATURES
PCIBX is a Hot Swap PCI, PCI-X extender card, compliant with PCI 2.2 specification. This extender card is able to isolate
voltages and signals to the UUT for Hot Swapping purposes via software control or the on-board mechanical switch. The
software interface is done with the system parallel port in order to not add any additional loading on the PCI signals and to
be able to control the extender from a different system than the one testing the UUT.
All PCI signals are switched during On/Off operation, except the JTAG signals which are routed straight through without
any isolation.
The On-Off may be controlled via mechanical switch or the software. The power control domination between the switch and
software is explained here:
On power up of the extender card, the extender can be controlled by the mechanical switch in the case where
software control is not available. Once the first software instruction is issued, the mechanical switch is disabled,
and the control of the extender is passed to the software.
In typical auto test applications it is suggested to leave the mechanical switch in the On position, so when the
system is powered up the BIOS can configure the PCI registers on the UUT. After the system has completed
booting user may issue SW commands (or continue to use the switch) to turn the power to the extender Off and
back On.
In addition to Hot Swapping the main voltages and signals , the PCIBX cards have the following features:
1)
Short circuit protection
2)
Software contro3.3Va ux.
3)
Register to allow to reading of the status of the PME# signal.
4)
On-board 3.3V source, 3 Amps
5)
5V
ó
3V signal translators for DUT
ó
System, jumper selectable
6)
I-to-V converters for +5V, +12V and +3.3V
7)
ADC converter to read DUT voltages and current measurement
8)
Board select jumper for multiple boards operation, 2 boards per system.
9)
Selectable RST#, fixed 150 ms or programmable reset width from 2.5 us to 5 seconds
10)
Registers to read the status of the RST#, 66 MHz enable, 32 bit or 64 bit operation and status of the UUT
power
11)
Frequency counter for measuring the slot clock speed
12)
Selectable power up +5V ramp, 50 us or 10 ms
13)
Detection of the DUT not being fully asserted in the extender. This detection works by detecting if both pins
B3 and B57 are connected to GND. If both signals are connected to GND it is assumed that the UUT is seated
correctly in the top connector.
14)
PCI-X power up initialization. This feature allows the user to define how the PCI-X signal is handled by the
extender. Options are UUT determines, forced to 66 MHz PCI-X or disabled. These option are selected by the
position of JP17.
