Package designs for fully functional and partially functional chips
A method including obtaining an operational status of a first processor core, where the first processor core is associated with a plurality of processor cores located on a chip; configuring a first IO block of a package design based on the operational status of the first processor core, where the package design is based on a fully functional chip; and configuring a stackup of the package design after configuring the first IO block for use with the chip.
1. A non-transitory computer readable medium comprising software instructions that, when executed by a processor, perform a method of designing a chip package comprising:
obtaining a chip package design configured for a fully functional chip;
evaluating a chip that includes a plurality of processor cores, wherein the evaluation includes obtaining an operational status of a first processor core of the plurality of processor cores;
configuring a first IO block of the package design based on the operational status of the first processor core;
configuring a stackup of the package design based on the configuration of the first IO block; and
outputting a modified package design based on the stackup,
wherein the operational status of the first processor core is defective and the chip is partially functional,
wherein configuring the first IO block comprises:
mapping an IO bump of an inner row of the first IO block to the first processor core; and
mapping an IO bump of an outer row of the first IO block to a second processor core of the plurality of processor cores,
wherein an operational status of the second processor core is active, and
wherein the first IO block is located on a periphery of the package design.

wherein configuring the first IO block comprises:
mapping a first sub-block of IO bumps to the first processor core; and
mapping a second sub-block of IO bumps to a second processor core of the plurality of processor cores,
wherein an operational status of the second processor core is active,
wherein the first sub-block and the second sub-block abut within the first IO block, and
wherein the first IO block is located on a periphery of the package design.
