A traditional hierarchical scan test approach has specific challenges, which can be drastically improved using a packetized test delivery mechanism. Tessent Streaming Scan Network (SSN) reduces the DFT planning and implementation effort up to 5x using packetized test delivery. With Tessent SSN, the compression and number of scan channels for a core are determined based on what results in the most compact pattern set for that core alone. Scan compression can be configured once and for all cores used in multiple designs. SSN automatically distributes the available network bandwidth among the active cores based on scan pattern volume for each core, eliminating whitespace in the test data.
