Abstract:
Conformance testing apparatus for testing the consumption of an electronic component (10) in a testing machine, the apparatus including:at least one electrical power supply circuit (240) for powering the component (10), which circuit includes current-measuring means for measuring the current taken by said electronic component (10);a test sequencer (230) suitable for executing a sequence (231) of test rows to be applied to the component (10); anda current measurement sequencer (250) suitable for executing a sequence (251) of measurement rows, each of which corresponds to a test row, and contains a measurement flag defined prior to execution of the test sequence (231) and representative of a command to perform or not to perform a current measurement;said apparatus being characterized in that said measurement sequencer (250) includes a multiple acquisition memory (252) having a plurality of acquisition rows, each of which corresponds to a measurement row of the measurement sequence (251) whose measurement flag is positive, said memory (252) including for each acquisition row:at least one limit value zone (B23, B24) in which a limit value (MLIM, mLIM) for the current taken by the electronic component (10) is written prior to execution of the test sequence (231); andat least one conformance zone (A23, A24) in which, for each measurement, a conformance flag (MFLAG, mFLAG) is written representative of the result of a comparison performed in a register (253) associated with said memory (252) between the current as measured and said limit value (MLIM, mLIM).
