Folks, we have several OEMs who perform Boundary-Scan (JTAG) testing of
CCAs.  These are ISO 9001 shops and ISO 9001 requirement 7.6 requires
that the ability of computer software to satisfy the intended
application shall be confirmed prior to initial use and reconfirmed as
necessary.

 

Since Boundary-Scan (JTAG) testing is software driven, the ISO
requirement would apply.  Basically, this is software Verification and
Validation (V & V).

 

How does one go about performing V&V for a typical moderately complex
CCA with sufficient detail to satisfy the ISO 9001 requirement? 

 

Since the OEM sub-contracted development of the JTAG software to a
supplier who does this for a living, we have some level of confidence it
was developed correctly (the OENM provided a golden board and electrical
schematic); however, we are looking for some cost effective method to do
a V & V to convince us the software was developed correctly.

 

Any help or tutorial on the subject would be appreciated.
