摘要： A tester for use with a device under test includes a processor, a signal timing editor to create representations of signal waveforms and associated times, and a test program executable on the processor that schedules events based on information from the signal timing editor. The test program schedules different delays for the events to compensate for variations in time delays between different signals coupled to the device under test.

摘要： A distributed tester method and system communicates test recipes for testing electronic devices from a host computer over a network to a test site. The test site translates test recipes into test instructions for execution by a test engine that determines the status of the electronic device. For instance, in a tester for testing memory, a test recipe is defined and stored with a host computer to determine test data for storage on the memory device under test at the test site. The host computer controls execution of the test recipe over the network. The test recipe is defined and stored in an XML formatted data file transmitted over the network to a processor at the test site. The test site processor translates the XML formatted data into test instructions for execution by a test engine. The test engine determines whether the memory device under test accurately stores data and provides the results, such as erroneously stored data, to the host computer through the network. A test design host and a global data master also interface with the network to aid the design and storage of test recipes. The distributed test method and system advantageously improves flexibility of testing over a geographically disbursed area and with divergent test recipes and devices under test.

摘要： A time conserving method of identifying width, depth, access time, control line configurations, and part type of any of a plurality of different synchronous memories. A nested loop process is used to develop, and apply to a synchronous memory being identified, trial control line configurations taken from ordered entries of tables representative of the plurality of synchronous memories. The width, depth, control line configurations, and part type are determined from the responses evoked from the synchronous memory being identified. The delay between a read command issued by the test system CPU and a reading of bit patterns from the synchronous memory is incremented in finite steps in successive write/read iterations until the bit pattern read is identified to the bit pattern written into the synchronous memory, thereby identifying the access time of the synchronous memory.
