Abstract: Embodiments of the present invention relate to providing fault-tolerant power minimization in a multi-core neurosynaptic network. In one embodiment of the present invention, a method of and computer program product for fault-tolerant power-driven synthesis is provided. Power consumption of a neurosynaptic network is modeled as wire length. The neurosynaptic network comprises a plurality of neurosynaptic cores connected by a plurality of routers. At least one faulty core of the plurality of neurosynaptic cores is located. A placement blockage is modeled at the location of the at least one faulty core. A placement of the neurosynaptic cores is determined by minimizing the wire length.

Abstract: A putative circuit design is represented as a set of movable blocks of predetermined size which must fit into a bounding box, with a plurality of subsets to be interconnected by wires. A total weighted wire length is determined as a function of coordinates of centers of the movable blocks by summing a half perimeter wire length over the plurality of subsets, and a density penalty is determined as a convolution of an indicator function of the current placement and a convolution kernel, via incremental integer computation without use of floating point arithmetic. Blocks are moved to minimize a penalty function which is the sum of the total weighted wire length and the product of a density penalty weight and the density penalty. The process repeats until a maximum value of the density penalty weight is reached or the density penalty approaches zero.
