Enhanced dummy die for MCP

Embodiments include semiconductor packages. A semiconductor package includes a plurality of dies on a package substrate, and a plurality of smart dies on the package substrate, where the plurality of smart dies include a plurality of interconnects and a plurality of capacitors. The semiconductor package also includes a plurality of routing lines coupled to the dies and the smart dies, where the routing lines are communicatively coupled to the interconnects of the smart dies, where each of the dies has at least two or more routing lines to communicatively couple the dies together, and where one of the routing lines is via the interconnects of the smart dies. The capacitors may be a plurality of metal-insulator-metal (MIM) capacitors. The dies may be a plurality of active dies. The routing lines may communicatively couple first and second active dies to first and second smart dies.
