CAzM is superior in speed, stability and convergence to the industry standard simulator, SPICE. CAzM is now being offered to interested users on a cost-recovery basis (see below). CAzM uses sophisticated numerical techniques including look up tables and an automatic time step adjustment scheme to ensure an accurate and fast simulation. CAzM is up to ten times faster then SPICE for average sized circuits (100-200 transistors) and the speed advantage tends to increases as the number of circuit elements increase. CAzM has excellent convergence properties. Circuits containing as many as 20,000 transistors have been simulated successfully. CAzM is a table based simulator. The tables contain charge and steady state current information about each device in a circuit. These tables can be measured directly, generated by a device simulator such as PISCES, or built in models can be used. Built in models are available for standard elements such as resistors, capacitors, and diodes. Available MOS models include SPICE level I and II current equations and the Ward-Dutton charge equations. The next release of CAzM (available early 1989) will include Level III, IV (BSIM), JFET, and BJT (bipolar) models. CAzM is netlist compatible with SPICE, with the extension that node names can be alphanumeric. The command language is similar to SPICE, but includes additional commands for specifying waveforms. CAzM runs on a variety of UNIX platforms including VAX, Convex, and Sun's (2, 3, and 4). CAzM is the standard circuit simulator used at the Microelectronics Center of North Carolina and its Participating Institutions for all chip designs. CAzM is available on an "as is" basis, under a site wide license agreement from MCNC.
