It is used to construct the static object that is registered with the dispatcher. It should do what a default constructor usually does. copy constructor A copy constructor is required. Most objects are created by the copy constructor, as copies of the object registered with the dispatcher. Usually, it should do a SHALLOW copy. In particular, a COMMON should be linked and not copied.

Syntax measure param-name = measurefunction(args) Comments The “measure” command sets parameters, like the “parameter” command, but the value after a measure is a number. It is used to make measurements on a circuit, such as slew rate, crossings, or average value. text/html 2009-10-04T12:51:19-05:00 aldavis http://flintradio.org/dokuwiki/doku.php?id=gnucap:manual:compatibility:subcircuit_with_parameters&rev=1254675079&do=diff Subcircuit with parameters Some simulators (LTspice, Pspice) accept a syntax for subcircuits that is incompatible with gnucap.

In some cases, a workaround is suggested. In almost all cases, there are plans to provide exact compatibility in the future. * subcircuit with parameters, Pspice, LTspice
