simulation technology combines industry-leading,
native analog and mixed-signal engines to deliver a complete circuit
simulation and verification solution. It meets the changing simulation
needs of designers as they progress through the design cycle, from
circuit exploration to design development and verification. Designed
for use in conjunction with PSpice A/D, PSpice Advanced Analysis
helps designers improve yield and reliability.
Many electrical engineers rely on setting up their circuits on a bread board to verify operation and
function of their designs. While this technique is a perfectly valid method for proof of concept, it
has inherent limitations. The length of time it takes an engineer to collect parts, wire them up on a
bread board, come up with a stimulus, and then manually measure the results can be significantly
reduced by using PSpice A/D and Advanced Analysis to simulate design circuits. Also, endless
component variations and combinations along with circuit stimulus make large-scale repetition of
any manual process time and cost prohibitive.
Manufacturing variations of the electronic components that make up the circuit can affect the
function and performance of the circuit. These manufacturing variations are generally expressed as
tolerances on the key specifications of the components. It is not usually possible or practical to test
a circuit to the complete range of tolerances of all the components. The tolerances of the compo-
nents can also affect some of the circuit properties such that the operating limits of some compo-
nents could be exceeded. Exceeding the operating limits can result in damage to a component,
causing the circuit to cease to function.
