17807 results about "Test efficiency" patented technology

Efficiency testing test the amount of code and testing resources required by a program to perform a particular function. Software Test Efficiency is number of test cases executed divided by unit of time (generally per hour). It is internal in the organization how much resources were consumed how much of these resources were utilized.

Real-time decoder for scan test patterns

A method and apparatus for improving the efficiency of scan testing of integrated circuits is described. This efficiency is achieved by reducing the amount of required test stimulus source data and by increasing the effective bandwidth of the scan-load operation. The reduced test data volume and corresponding test time are achieved by integrating a real-time test data decoder or logic network into each integrated circuit chip. The apparatus, servicing a plurality of internal scan chains wherein the number of said internal scan chains exceeds the number of primary inputs available for loading data into the scan chains, includes: a) logic network positioned between the primary inputs and the inputs of the scan chains, the logic network expanding input data words having a width corresponding to the number of the primary inputs, and converting the input data words into expanded output data words having a width that corresponds to the number of the internal scan chains; and b) coupled to the internal scan chains, registers loaded with bit values provided by the expanded output data words while data previously loaded into the scan chains shifts forward within the scan chains by one bit position at a time; wherein a first plurality of the input data words supplied to the primary inputs produce a second plurality of expanded data words that are loaded into the internal scan chains to achieve an improved test coverage.

Active optical module multi-channel automatic test system and method

The invention provides an active optical module multi-channel automatic test system and a method. optimal signals emitted by a tested optical module are monitored, and indexes of the incident light power, emission current, bias current, temperature, voltage, extinction ratio, eye diagram allowance, crossing point, OMA (optical modulation amplitude) etc. are measured and calculated; if the above indexes are all in accordance with the standard, the sensitivity of the optical module is tested, the emission optical power of the tested module is enabled to reach the sensitivity of the test standard via the adjustment of an attenuator, and error code tests are conducted; and if there is no error code, indexes of alarm value and alarm recovery etc. of the optical module are tested. According to the test system, an error detector, an optical module test board, an optical power meter, and the attenuator employed by the test system are all multi-channel devices, an optical switch and an optical splitter are combined for time-sharing multiplexing of one oscilloscope, at least 8 modules can be simultaneously tested, the utilization rate of the oscilloscope and the test efficiency of the optical module are greatly optimized, the equipment cost and the manual cost are reduced, and automatic and batch production of the optical modules is realized.
