Generation of intermediate representations based on user specified elements in a graphical model that enable simulation, propagation and code generation

A system comprising:

• a model of a system, the model having two or more elements;
• a first intermediate representation of the two or more elements, the first intermediate representation capturing one or more operations associated with at least two elements in the model;
• and
• a processor for:
• identifying one or more underlying operations captured in the first intermediate representation that are not supported by a simulator,
• converting the identified one or more underlying computations into one or more computations that are supported by the simulator,
• capturing the converted one or more computations in a second intermediate representation, the first intermediate representation, the second intermediate representation, and the model being different representations of the system, analyzing, using a dispatcher, the second intermediate representation to identify one or more operations and replacing the identified one or more operations with one or more operations selected to achieve a desired objective;
• and
• directing the simulator to simulate at least a portion of the model by executing the second intermediate representation.

A non-transitory medium for use on a computing device, the non-transitory medium holding instructions executable using the computing device, the instructions for:

• converting two or more elements of a graphical model of a system to a first intermediate representation, the first intermediate representation being a data structure that captures operations associated with the at least two elements;
• converting the first intermediate representation into a second intermediate representation that is capable of being executed by a simulator, the first intermediate representation, the second intermediate representation, and the model being different representations of the sytem, the converting including:
• identifying one or more operations captured in the first intermediate representation that are not supported by the simulator,
• converting the identified one or more operations into one or more operations that are supported by the simulator, and
• capturing the converted one or more operations in the second intermediate representation;
• analyzing, using a dispatcher, the second intermediate representation to identify one or more operations and replacing the identified one or more operations with one or more operations selected to achieve a desired objective;
• and
• simulating the at least two elements by executing the second intermediate representation.

In a graphical modeling environment, a method comprising:

• converting, using a processor, two or more elements of a block diagram model representing an elemental dynamic system to a first intermediate representation, the first intermediate representation being a simulatable control flow graph that captures operations associated with the at least two elements, the first intermediate representation having at least one of data or a model characteristic, associated with a converted element, that can-not be propagated;
• converting the first intermediate representation to a second intermediate representation that enables propagation of the at least one data or model characteristic that could not be propagated;
• and
• propagating the at least one data or model characteristics that could not be propagated using the second intermediate representation analyzing, using a dispatcher, the second intermediate representation to identify one or more operations and replacing the identified one or more operations with one or more operations selected to achieve a desired objective.

A non-transitory medium for use on a computing device for providing an element for a block diagram model, the non-transitory medium holding instructions executable using the computing device, the instructions for:

• converting two or more elements of a block diagram model represendting an elemental dynamic system to a first intermediate representation, the first intermediate representation being a simulatable control flow graph that captures operations associated with the at least two elements;
• converting the first intermediate representation to a second intermediate representation that enables propagation of the at least one data or model characteristic that could not be propagated;
• and
• propagating the at least one data or model characteristics that could not be propagated using the second intermediate representation analyzing, using a dispatcher, the second intermediate representation to identify one or more operations and replacing the identified one or more operations with one or more operations selected to achieve a desired objective.
