We present the design and implementation details of a time-division demultiplexing/multiplexing based scan architecture using serializer/deserializer. This is one of the key DFT features implemented on NVIDIA’s Fermi family GPU (Graphic Processing Unit) chips. We provide a comprehensive description on the architecture and specifications. We also depict a compact serializer/deserializer module design, test timing consideration, design rule and test pattern verification. Finally, we show silicon data collected from Fermi GPUs.
