3.5 Setting Up and Solving Circuit Equations 239
Protocol
This option describes the standard Analog Insydes protocol specification (see Section 3.14.5). The
top-level function for the Protocol option is CircuitEquations. The second-level function is
ExpandSubcircuits. Protocol output generated by models is printed as third level.
Symbolic
The Symbolic option gives you control over the set of symbolic parameters of behavioral models
which are kept as symbolic quantities in a system of circuit equations. The Symbolic option is the
complement of the Value option and expects the following values:
All
None
{instances −> params, † † † }
keep all symbolic parameters of behavioral models in
symbolic form
replace all symbolic model parameters by numerical values
keep only the specified parameters from the given
instances in symbolic form
Values for the Symbolic option.
If the value form {instances −> params, † † † } is chosen, both instances and params can be a string
pattern or a list of string patterns. The instances specification may have the following format:
"pattern"
{"pattern
", "pattern
", † † † }
matches any reference designator "refdes" for which
StringMatchQ["refdes", "pattern"] yields True
matches any reference designator that matches at least one
of the patterns; patterns are evaluated in the given order
Format specifications for instances.
The params specification may have the following format:
symbol
"pattern"
{"pattern" | symbol, † † † }
matches symbol literally
matches any symbol arg for which
StringMatchQ[ToString[arg], "pattern"] yields True
matches any symbol that matches at least one of the
patterns; patterns are evaluated in the given order
Format specifications for params.
