Abstract
Presented herein are systems, methods, and devices for analyzing a circuit. A netlist is obtained and parsed, where the netlist describes the circuit having one or more branches and one or more nodes. A linear system describing the circuit is obtained and compressed using a hierarchical approach. Compression involves storing off-diagonal sub-blocks in a dense matrix in a low-rank format to reduce the density of the matrix. The linear system is then solved using an iterative operation. An initial guess is used for the voltage at each node and the current through each branch. After performing the first iteration, an initial estimate for the voltage and current is stored and used as the initial guess for the second iteration. The iterative operation is continued until the estimate for the voltage at each node and the current through each branch is sufficiently accurate.
