Module with trigger bus for SOC tester and a method of timing calibration in the module

摘要

A module in a module-type tester has a trigger bus for trigger signals and sub-modules; at least one of the sub-modules has a terminal for receiving trigger signals from the trigger bus and a terminal for outputting trigger signals to the trigger bus; and at least one of the sub-modules receives trigger signals from outside the module at a terminal for measurement signals or a terminal for signals under test and outputs the received trigger signals to the trigger bus via the output terminal.
