 This tutorial will introduce the [`NeuralNetworkBlock`](@ref). This representation is useful in the context of hierarchical acausal component-based model.
 
 For such models we have a component representation that is converted to a a differential-algebraic equation (DAE) system, where the algebraic equations are given by the constraints and equalities between different component variables.
-The process of going from the component representation to the full DAE system at the end is reffered to as [structural simplification](https://docs.sciml.ai/ModelingToolkit/stable/API/model_building/#System-simplification).

 The advantage of the component UDE formulation is that it allows us to represent the model
