Analog InsydesDefinicion de elementos:{reference designator, {connectivity list},value field}The reference designator is a unique name by which a particular circuit element can be distinguishedfrom all other elements in the same netlist.The connectivity list specifies the nodes of the circuit to which the terminals of an element areconnected.the values of circuit elements need not be purely numerical quantities. Since Mathematica is capable of performing mathematical calculations symbolically, the element values may also be any symbolic or mixed symbolic/numeric expressions.

Barridos de elementosPag. 282Formatdescription

{symbol, {f1, , fm}}symbol has values f1, , fm

{symbol, start, stop, incr}equivalent to {symbol, Range[start, stop, incr]}

{{symb1->f11, , symbn->f1n}, , {symb1->fm1, , symbn->fmn}}First, symb1 has value f11, , and symbn has value f1n, and so forth. In the last step, symb1 has value fm1, , and symbnhas value fmn

{sweep1, , sweepm}combinations of the above sweep formats

The following example shows valid parameter sweeps:{{R1, {100, 1000, 10000}},{V1, 1, 5, 1},{{P1 -> 10, P2 -> 20}, {P1 -> 20, P2 -> 10}}}

Condiciones inicialesInitial conditionsWith the InitialCondition option (see Section 3.1.4), you can specify initial currents and voltagesfor the dynamic elements Inductor (Section 4.2.6) and Capacitor (Section 4.2.5), respectively. If noinitial condition is given explicitly, it will be assumed to be zero (AC analysis) or will be calculatedautomatically from the operating-point data (transient analysis).{refdes, {nodes}, Value -> value,Symbolic -> symbolicvalue,Pattern -> pattern,Type -> type,InitialCondition -> initialcondition}Example{C1, {2, 0}, Value -> C1, InitialCondition -> V0}

Start point en DCInitialGuessThe option InitialGuess allows for explicitly specifying an initial guess for the Newton iterationwhen computing the operating point. Note that missing variables are set to zero. The default settingis InitialGuess -> Automatic, which means that all variables have the initial value zero. Possibleoption values are as follows:

Automatic uses zero values as initial guess{var1 -> value1, } uses specified values as initial guess and sets values not specified to zero

Values for the InitialGuess option.

Cambiar metodo de integracion,analog usa mathematica para sus metodos que por default es FindRootNonlinearMethodThe option NonlinearMethod allows for choosing between different algorithms for numericallysolving nonlinear equation systems. The default setting is NonlinearMethod -> FindRoot. Validoption values are as follows:

FindRoot uses Mathematicas numerical equation solver FindRootNewtonIteration uses multi-dimensional Newton-Raphson implementationValues for the NonlinearMethod option.
