Circuit optimization for digital circuits. John Peter Stevenson, Stanford. LargeRegFile is a matrix representing an optimization problem. Specifically, it is a geometric program, a kind of convex optimization problem. The matrix entries are the exponents found in the geometric program constraints; specifically, this matrix is a portion of the input required by mskexpopt: http://docs.mosek.com/6.0/capi/node008.html This matrix represents a digital circuit. The circuit is a large register file: 256 registers, 64 bits each, 2 read ports, 1 write port. The optimization problem is to minimize circuit delay, subject to constraints on energy cost and area cost. The optimization variables are the transistor size, the supply voltage, and the threshold voltage. The circuit optimization method is described by Patil, et. al.: Robust energy-efficient adder topologies.
