Abstract
Linear signal flow [1] (LSF) formalism enables us to model, analyze, and explore the design space of any non-conservative system with continuous time and directed real-valued signals. When represented as a graph, LSF modules are the nodes and the unidirectional arcs between the nodes are the channels, and it fits perfectly with the TLM paradigm of processing elements communicating via channels. Specifically the LSF formalism enables modeling/analysis of an AMS system defined in terms of relations between variables of a system of linear algebraic equations. Unlike TDF, the formalism is restrictive—the user cannot write customized code for the model, but only use members of a pre-defined set of LSF models (addition, subtraction, multiplication, derivative, etc.), as required.
