3D integration is a promising new technology for tightly integrating multiple active silicon layers into a single chip stack. Both the integration of heterogeneous tiers and the partitioning of functional units across tiers leads to significant improvements in functionality, area, performance, and power consumption. Managing the complexity of 3D design is a significant challenge that will require a system-on-chip approach, but the application of SOC design to 3D necessitates extensions to current test methodology. In this paper, we propose extending test wrappers, a popular SOC DFT technique, into the third dimension. We develop an algorithm employing the Best Fit Decreasing and Kernighan-Lin Partitioning heuristics to produce 3D wrappers that minimize test time, maximize reuse of routing resources across test modes, and allow for different TAM bus widths in different test modes. On average the two variants of our algorithm reuse 93% and 92% of the test wrapper wires while delivering test times of just 0.06% and 0.32% above the minimum. |
