Abstract: In automatic test equipment (ATE), the current state of all configurable hardware components is maintained in one or more status registers. A configuration interface operates between the ATE test program and the hardware components. The test program issues instructions for configuring the hardware components to the configuration interface, which considers the current configuration status of each hardware component stored in the status registers. When a hardware component is instructed to assume a specific configuration for a given task, the configuration interface compares the target configuration with the current configuration status and forwards the instruction only if they are different, i.e., if the current hardware configuration must be updated. The associated wait times for instructions issued where the target configuration matches the current configuration status are avoided, decreasing setup time.

Abstract: An automatic configuration system automatically analyzes a user's computer system configuration and recommends a more optimal configuration of components. The system determines the hardware and software components currently contained in the user's computer including versions of hardware and software components. The system uses a knowledge base of previously identified problems to determine an overall problem index value for the user's particular configuration.

The system selects the configuration with the lowest overall problem index value, which generally will have the fewest and/or less severe problems and recommends that configuration to the user.
