Abstract: There is provided a method for verifying inter-stratum connectivity for two or more strata to be combined into a 3D chip stack. Each of the two or more strata has 3D elements including active 3D elements, mechanical 3D elements, and dummy 3D elements. The method includes performing a respective 2D layout versus schematic verification on each of the two or more strata with respect to at least the 3D elements to pre-ensure an absence of shorts between the 3D elements when the two or more strata are subsequently stacked into the 3D chip stack. The method further includes checking inter-stratum interconnectivity between each adjacent pair of strata in the 3D chip stack.

Abstract: A mechanism is provided for protecting a layer of functional units from side-channel attacks. A determination is made as to whether one or more subsets of functional units in a set of functional units in the layer of functional units is performing operations of a critical nature. Responsive to a determination that there is one or more subsets of functional units that are performing the operations of the critical nature, at least one concealing pattern is generated in a concealing layer in order to conceal the operations of the critical nature being performed by each of the subset of functional units. The concealing layer is electrically and physically coupled to the layer of functional units.

Abstract: A method for pre-wiring through multiple levels of metal using flues includes steps of: receiving information comprising flue geometries and flue properties; producing multiple routing patterns of a design for the flues; identifying macro instance terminals to be pre-wired in the design; selecting at least one of the routing patterns for the macro instance terminals in the design to avoid blockage; and instantiating the design such that the flues can be manipulated as vias.
