Abstract
A semiconductor integrated circuit 10 includes a digital/analog conversion circuit 6. Test signals, which are supplied through signal lines Sig0T through Sig3T, are supplied to the digital/analog conversion circuit 6 via input terminals 5A through 5D, respectively. The digital/analog conversion circuit 6 converts the test signals (digital signals) into an analog signal and supplies the analog signal via an output terminal 7 to a signal line So. The analog signal supplied through the signal line So is externally outputted via a external output terminal 4. This achieves a semiconductor integrated circuit suitable for miniaturization.
Claims10
A semiconductor integrated circuit comprising:
- a test circuit for (i) checking whether or not a circuit operates normally and (ii) outputting an encoded signal indicating a result thus checked;
- and
- an analog conversion circuit for (i) converting the encoded signal supplied from the test circuit into an analog signal and (ii) externally outputting the analog signal.
