Abstract

A method for communicating test information from a source to a destination is disclosed. The method includes providing a modular test system, where the modular test system comprises a system controller for controlling at least one site controller, the at least one site controller for controlling at least one test module. The method further includes providing a datalog framework for supporting extension of user-defined datalog formats, providing support classes for supporting user-initiated datalog events, receiving a datalog event requesting for communicating input test information from the source to the destination, configuring output test information based upon the destination, the datalog framework and the support classes,and transferring the output test information to the destination.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of provisional application no. 60 / 573,577 "Software Development in an Open Architecture Test System," filed May 22, 2004, by Advantest Corporation, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to the field of automated test equipment (ATE). More specifically, the present invention relates to a method and system for supporting data logging in an open architecture test system. Background technique [0004] The increasing complexity of system-on-chip (SOC) devices and the simultaneous need to reduce the cost of testing chips has forced integrated circuit (IC) manufacturers and tester vendors to rethink how IC testing should be performed. Industry studies have shown that without re-engineering, the projected cost of testers will continue to increase significantly in the near future. [0005] A major reason for...
