Abstract: A method and associated algorithm for controlling and optimizing the temperature of a device under test (DUT) through calculation of a moving setpoint which varies from the user-specified DUT core temperature. The method generally comprises (i) calculating a system operating range based on limits imposed by the DUT, associated temperature control system, and thermal conditioning equipment; (ii) determining the allowable operating range for the DUT based on permissible DUT stress and DUT core temperature; and (iii) calculating a control setpoint based on DUT and conditioning system temperature data, one or more pre-selected setup factors, and the system and DUT operating ranges. In another aspect of the invention, variable temperature differential limits are imposed on the CSP as a function of DUT core temperature in order to mitigate thermal shock to the DUT. Methods and apparatus for latent temperature control are also disclosed.

Abstract: A method for safely adding nodes to a network provides safeguards to prevent adding nodes beyond a maximum number of nodes allowed in the network. In one aspect, if the node to be added exceeds the maximum number of nodes allowed, the connection between the node to be added and the network is quarantined. If the node to be added does not exceed the maximum number of nodes allowed, the connection is confirmed. In another aspect, an additional test is made to determine if the connection between the network and the node to be added creates a loop within the network. In the case of a detected loop, the connection between the network and the node to be added is quarantined. If the connection does not create a loop, it is confirmed.

Abstract: A method for configuring a computer network so that no non-root node can allocate itself a Physical_ID reserved for a root node. For each node that executes the self_ID process, a check is made of the available Physical_ID value as well as the designation of the node as a root or non-root node. If the value available is less than a value reserved for a root node, the value is assigned to the node. If the value not less than the value reserved for root node, a check is made to see if the node is a root node. A root node is assigned the value reserved for root. Non-root nodes are assigned a value that is greater than the value reserved for root node. After the value is assigned, the value-node assignment is broadcast over the network and the available pool of values is updated.

Abstract: A dynamic configuration ROM which may be updated while linked to the serial bus and with little or no risk of publishing inconsistent configuration ROM information to the other nodes on the bus. The dynamic configuration ROM comprises first and second configuration ROM images, one set to active, the other set to update. The dynamic configuration ROM publishes the configuration entries form the “active” configuration ROM image. Modifications to the configuration ROM are stored in a database. The “update” configuration ROM image is constructed from entries made to the database. After the construction of the “update” configuration ROM image is completed, the dynamic configuration ROM switches the states of the ROM images and transmits a serial bus reset signal. Subsequently, the configuration entries from the newly “active” configuration ROM image are then published.
