Abstract:
1. A test module used in a test apparatus for testing an electric device, comprising: a plurality of signal input-output units for: generating a test signal inputted to said electric device, comparing a signal outputted from said electric device in response to the test signal inputted with an expected signal, and inputting and/or outputting test signals in response to each of a plurality of terminals of said electric device when set according to a setting condition provided for performing a test; a channel selection memory for storing pieces of channel selection information indicating whether each of said signal input-output units should perform a setting based on a setting condition in advance of starting the testing; a setting condition memory for storing said setting condition with regard to said signal input-output unit in advance of starting the testing; and a controlling means for retrieving and supplying said setting condition stored in said setting condition memory and said channel selection information stored in said channel selection memory to said signal input-output units based on a setting instruction, when receiving said setting instruction to set said setting condition of said signal input-output unit, wherein when at least one of said signal input-output units is selected by said channel selection information supplied from said controlling means, said one of said signal input-output units is set based on said setting condition supplied from said controlling means, wherein said test module corresponds to said electric device having a unique test pattern, and wherein said setting condition memory stores said setting condition of said signal input-output unit and an address of said channel selection memory in a corresponding manner, and said controlling means comprises: a setting condition retrieving unit for retrieving said setting condition and said address of said channel selection memory from said setting condition memory; a selection information retrieving unit for retrieving said channel selection information from said channel selection memory based on said address of said channel selection memory retrieved by said setting condition retrieving unit; and a setting condition supplying unit for supplying said setting condition retrieved by said setting condition retrieving unit and said channel selection information retrieved by said selection information retrieving unit to said signal input-output units, wherein said setting condition retrieving unit retrieves said setting condition comprising pieces of setting data and said addresses of said channel selection memory in response to each of said pieces of setting data from said setting condition memory, said selection information retrieving unit retrieves pieces of said channel selection information from said channel selection memory based on said addresses of said channel selection memory retrieved by said setting condition retrieving unit, and said setting condition supplying unit supplies said pieces of setting data retrieved by said setting condition retrieving unit and said pieces of channel selection information retrieved by said selection information retrieving unit to said signal input-output units.
