Component handlers are functions that are defined on the component level.
Table 1 contains
a summary of the
Component handler functions possible for Schematic Editor components.
Table 1. Component handlers
| Component handler |
When executed |
| init |
- Called during model loading, and when a component is added to
the schematic.
- Used to initialize the component.
- In the case of a subsystem, it can be used to define functions and
variables which can be accessed by inner components.
- Parameters:
- mdl - Schematic API object,
- item_handle - item handle object.
|
| pre_compile |
- Called during model compilation, when hard evaluation
(errors are reported) of component/mask properties is
performed.
- Used to perform validations of component/mask properties.
- In the case of a subsystem, it can also be used to update the
namespace with variables that can be accessed by its inner
components.
- Properties depending on the terminal signal types or
dimensions may still be unresolved.
- Parameters:
- mdl - Schematic API object,
- item_handle - item handle object.
|
| post_resolve |
- Called during model compilation, after terminal signal types
and dimensions are resolved.
- Used to perform validations of component/mask properties.
- Values of all properties are resolved at this point.
- Parameters:
- mdl - Schematic API object,
- item_handle - item handle object.
