A test circuit can use a simple test pattern data without customization for each substrate and considerably reduce a test preparation process. A connection test circuit is generated by receiving the input of the data of the connection relation indicating the devices mutually line-connected among a plurality of devices, the number of connection lines corresponding to the respective connection relations, and the device outputting a test result, sequentially searching for a connection destination device from the output terminal of an output device, and embedding a test circuit module in a test route.
