ISch_MapDefiner

Overview
The ISch_MapDefiner interface represents the object that is used to define a mapping between schematic pins of a schematic component and its model for example the associated PCB pad objects of the PCB component in the same PCB project.

This interface is part of the ISch_Implementation interface. Each component can have a number of implementations (models of the same type and/or different types as well).

The ISch_Implementation.DefinerByInterfaceDesignator returns you theISch_MapDefiner interface with the Designator string representing the component’s designator text string.

Notes
A model represents all the information needed for a component in a given domain, while a datafile entity (or link) is the only information which is in an external file.

A model can be represented by external data sources called data file links. For example, pins of a component can have links to different data files, as for signal integrity models. We will consider each model type in respect to the data file links for the main editor servers supported in Altium NEXUS.

For the PCB footprints, the model and the data file are both the same.

With the simulation models, you can have a simulation model which is a 4ohm resistor for example, there is a simulation model but there is no information is coming from an external file, therefore, a no external file is needed for this as the resistor model is built from spice. This is the case where you have a model with no data file entity. Thus the parameters are used for these types of simulation models that don’t have data file links.

With signal integrity models, it can have information required for each pin. If we used IBIS datafiles, not the Altium NEXUS’s central database, then each signal integrity model would then have multiple data files, each one for each type of pin.

The ISch_MapDefiner interface hierarchy is as follows;

ISch_Implementation Interface

Overview
Each schematic component can have models from one or more domains. A schematic component can also have multiple models per domain, one of which will be the current model for that domain.

A model represents all the information needed for a component in a given domain, while a datafile entity (or link) is the only information which is in an external file.

The models of a component are represented by the ISch_Implementation interface.

The mapping of pins of a component and the nodes/pads of a model are represented by the ISch_MapDefiner interfaces.

The link between a model and its external data file links are represented by the ISch_DataFileLink interfaces.

Notes
A model can be represented by external data sources called data file links. For example, pins of a component can have links to different data files, as for signal integrity models. We will consider each model type in respect to the data file links for the main editor servers supported in Altium NEXUS.

For the PCB footprints, the model and the data file are both the same.

With signal integrity models, it can have information required for each pin. If we used IBIS datafiles, not the Altium NEXUS’s central database, then each signal integrity model would then have multiple data files, each one for each type of pin.

A model can also be called an implementation. Each implementation linked to a component can have parameters and data file links.
