Iddq is for CMOS circuit Testing. For example, for an inverter, not matter you input 1 or 0, either pmos or nmos is off. Depending on your input 1 or 0, 1 for testing pmos off and 0 for testing nmos off. It is an aid for testing internal core that pattern vectors is hard to reach.
But now it is not a mainstream, Scan is more easy and provide more testing covery. |
