Implementing vertical die stacking to distribute logical function over multiple dies in through-silicon-via stacked semiconductor device

A computer-implemented method for implementing stacking distribution of a logical function over multiple dies in through-silicon-via (TSV) stacked semiconductor devices, a computer performing the steps of said computer-implemented method comprising:

• using the computer, providing predefined functional logic for implementing a respective predefined function included in each respective die in a die stack;
• arranging each respective die in the die stack for executing the respective predefined function and providing a respective functional result signal output to a next level adjacent die in the die stack using TSV interconnections for combining the respective functional result signal output with the respective predefined functional logic of the next level adjacent die;
• providing die identification logic included in each respective die in a die stack;
• forming an operational die signature by combining a plurality of selected signals on each die;
• and to provide a die signature to a next level adjacent die in the die stack using TSV interconnections combining the die signature with the die signature of the next level adjacent die;
• and
• identifying a de-selected die in the die stack, and using a spare die in the die stack bypassing the identified de-selected die.
