Abstract
A novel method and apparatus for automatically programming a redundancy map for a circuit is presented. A circuit comprising a plurality of identical reconfigurable circuit elements and a redundant circuit element includes a redundancy map register which may be programmed to allow faulty circuit elements to be deactivated and bypassed and the redundant circuit element to be activated. A fault detector tests the circuit to generate a fault indicator indicating which one of the reconfigurable circuit elements is a faulty circuit element. An encoder encodes the fault indicator into an encoded fault indicator. A decoder decodes the encoded fault indicator to generate a redundancy map for configuring the reconfigurable circuit elements.
