Abstract

Disclosed is a system design that permits configuration-dependent hardware (hooks) of a computer system to be exercised. The invention is unique in that this targeted hardware can be stressed and tested in a system environment without requiring a fully configured system. Also, the targeted hardware is exercised simultaneously with the stress and test of the mainline function of the computer.

System Level Hooks Exerciser

      Disclosed is a system design that permits
configuration-dependent hardware (hooks) of a computer system to be
exercised.  The invention is unique in that this targeted hardware
can be stressed and tested in a system environment without requiring
a fully configured system.  Also, the targeted hardware is exercised
simultaneously with the stress and test of the mainline function of
the computer.

      Computer systems generally include an upgrade path or facility
to allow the customer to add compute power as his computing demands
grow.  Typically, the customer will add processors, channels, or
memory.  This creates a problem for the plant of manufacture when
testing the original system.  The problem is that there is some
computer logic/hardware in the machine that normally get exercise
only when the aforementioned add on hardware is present.
Historically, the problem has been solved by building the machine to
a maximum configuration, testing the system and then removing parts
to return to the configuration the customer ordered.  The solution is
very expensive because of the added inventory and material management
logistics required for its implementation.

      The logic design offered to address the hooks test problem
consists of a command and data generator on each of the subproducts
to which add on hardware is attached.  This generator supplies both
commands and data onto the unused interface.  This activity drives
