CAzM (Circuit Analyzer with Macromodeling) is a circuit simulation
tool developed jointly by Duke University and the Microelectronics
Center of North Carolina.  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.
