AgO AnXplorer Circuit Optimization Tool for Analog and RF Design

AgO introduced AnXplorer, which is a circuit optimization tool for analog and RF design. Its optimization is based on either simulation or equations. The tool works with industry standard SPICE netlists and supports industry standard simulators including Synopsys HSPICE, Cadence Spectre and Legend Design Technology MSIM. It runs on the Linux operating system. Starting with an unsized SPICE netlist, variables for device dimensions and a set of design objectives and constraints, AnXplorer optimizes device sizes by exploring the design space.

AnXplorer can fit into commonly used design toolsets as it works with industry standard SPICE netlists and simulators. A designer can create an unsized circuit, design variables and objectives. AnXplorer will then generate an optimized, centered circuit that meets or exceeds the design objectives across all corners specified by the user. It uses a new multi-algorithmic optimization strategy aided by an expert system.

Users can control the way optimization takes place by defining a hierarchy of design objectives. Unlike weighted-based handling of multiple objectives, the tool tries to meet high priority objectives before optimizing lower priority ones. AnXplorer’s design exploration database records all points during the optimization process. This enables designers to undertake what-if analysis or to trade off conflicting objectives if all objectives cannot realistically be met.
