Analog circuit simulation Log includes a full-featured analog circuit simulation package, Analog, written by John Lazzaro. Circuit schematic editing and parameter adjustments can occur while the simulator is in operation, supporting the metaphor of a virtual lab workbench. Model components include MOS transistor models optimized for accurate simulation in the weak-inversion regime, and macromodels of several of the circuits featured in Carver Mead's book Analog VLSI and Neural Systems. Circuit schematic editing and parameter adjustments can occur while the simulator is in operation, supporting the metaphor of a virtual lab workbench. Circuit libraries include many 7400-series TTL parts, and hard macros for early Actel FPGAs.
Hierarchical simulation is supported.
The log package includes a standalone gate editor, Loged, for creating custom gate icons. Loged can also generate data-sheets showing gate symbols and attributed, the the Postscript format. Log is the most popular Chipmunk tool, and has founded many uses in academia and industry. Log can serve as a cost-free alternative to commercial tools like ViewLogic, for users with simple needs.
