RE: PCI Card Testing



Hello William or Dayne,

You will find it very difficult to perform IEEE 1149.1 tests of PCI
cards through the motherboard
they are intended to function in.
In order to be successful, you would need to scan through all the IC's
on the motherboard.
This will require having the proper BSDL (Boundary Scan Description
Language) files for
all the devices on the vendor's MB as well.  It would also require
knowing how the
nets on the PCI bus map to the 1149.1 devices on the MB.  This may
require the netlist
for the motherboard.   If you have a close relationship with the MB
manufacturer, this may
be possible.  Some vertically integrated houses, in fact do this. Being
able to perform 
entire system interconnect tests with PCI daughter cards through IEEE
1149.1.
However for most companies making PCI daughter cards, the better
solution
is dedicated hardware for 1149.1 and PCI bus test.  With dedicated
hardware, you will
be able to stimulate/observe all the PCI bus signals of your daughter
card, regardless of
the design/support of 1149.1 in the MB.  Something to consider.

CJ Clark
Chair, IEEE 1149.1
