ABSTRACT
PSpice has commands for performing various analyses, getting different types of output, and modeling elements. These commands begin with a dot and are known as dot commands. A function statement can be used to define functions that may be used in expressions. The functions are defined by users and are, therefore, flexible. They are also useful for overcoming the restriction that expressions be limited to a single line and for the case where there are several similar subexpressions in a single circuit file. PSpice has the capability of defining global nodes. These nodes are accessible by all subcircuits without being passed in as arguments. Global nodes may be handy for such applications as power supplies, power converters, and clock lines.
