Master-Slave based test cost reduction method for DNN Accelerators

Umair Saeed Solangi, Muhammad Ibtesam, Sungju Park
2021 IEICE Electronics Express  
To achieve reduction in test time of accelerators, broadcasting of test patterns is used for simultaneous testing of processing elements (PEs).  ...  However, number of PEs tested simultaneously is limited because of scan shift power constraint.  ...  For this, parallel connections among respective scan FFs are made, this connection is called scan-connection. Slaves are scan-connected with Master and neighboring Slave.  ...
