Title: System lsi
Inventor: KAMIYA MASAKI
IPC: G01R31/28
Filed: 2001-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a system LSI which is equipped with an integrated AD converter, whose characteristics can be checked accurately, when only the A/D converter is tested. SOLUTION: A system LSI is switched from a normal signals path to a test signal path, when an A/D converter 101 is tested. When the system LSI is switched to a test signal path, digital signals outputted from the A/D converter are converted to analog signals through a circuit 107, and the analog signals are outputted by the use of an output buffer 108, which is additionally provided as an analog buffer for testing. Since a digital buffer, which generates a through-current and enables noises to occur in a power supply voltage as a reference voltage is not used, noises can be reduced, and a test can be improved in accuracy. Testing is improved in accuracy, so that it can be determined accurately in a test carried out before delivery as to whether the system LSIs are defective, and the system LSIs can be improved in yield.  The characteristics of the AD converter can be easily evaluated, even at a design stage, so that the development time can be shortened.
