Abstract
The invention provides a circuit and a determining method which can easily and accurately determine each time of propagation delay in a propagating line of a plurality of testing signals of an IC device interface of an IC tester. In the propagation line of the test signal from an IC device interface part (33) of an IC tester, a connector is used so that the IC device interface part (33) of the IC socket board (A1) has a releasable construction. An IC socket board (B31), which is in the same group as the IC circuit board (A1), has its conductor removed from the through hole thereof and is connected to the IC device interface part (33). The IC socket board (B31) is detached after only the intended TPDA11 is determined directly, and, in place of the IC socket board (B31), the IC socket board (A1) is attached. An easily interchangeable construction is provided as such for testing.
