Accusim is one of the main analog and mixed signal simulation tools in the MGC Falcon Framework family. It features an elaborate GUI through which schematic design information, simulation commands and device model data are passed on to the simulation kernel. As in many other simulation tools with a schematic front end, accusim generates a SPICE compatible netlist automatically from the design information available at the time the tool is invoked on a design. This kind of environment is especially attractive for large designs in which manual netlist preparation is not practical. The down side of this convenience is that the GUI and schematic data add a significant burden to the tool and slows down the simulation process. Simulators which are invoked on netlists are usually faster than those which are invoked on schematics within a GUI environment. Fortunately, accusim can be invoked in either mode giving users two tools in one.

The purpose of this presentation is to focus on the less familiar netlist mode of accusim and demonstrate the ease of use, increased productivity and simulation time savings involved. It will be shown through selected examples how to effectively extract waveform measurements using Eldo simulation commands some of which may not be currently supported in the GUI environment.
