Components and Constraints


The Assembly constraints (geometrical constraints) linking the components to the boarddepend on the component status.

Component Status Assembly ConstraintUnplaced No Constraint

Placed Plane to Plane ConstraintFixed Fixity Constraint

This information is transmitted through the import file (.idf), the component capability tochange location is then driven by the constraint.

Under certain circumstances, a component status can be modified:from unplaced to placed or fixedfrom placed to fixed

but never from fixed to placed or unplaced, nor from placed to unplaced (in order to keep theinformation defined in the ECAD world).

Editing the constraint lets you modify the offset between the component and the board(IDF 3.0):

The IDF 3.0 takes into account the offset which represents a mounting constraint ofthe component onto the board.

2.

The offset is also managed between the board and the panel.

Error File ReportingThis task explains what happens when the file import does not operate properly.

The scenario is described in Opening an IDF File.

During the import, if a problem is detected, the import operation continues and theitems generating an error are listed in a report file:

The CATProduct resulting from the import is incomplete, it's to say that somecomponents or areas or parts of the board can be missing or incomplete but theimport itself has finished.

Catalog Creation



Note that you can store several components at the same time in the catalog.

Catalog Creation


Importing Using a CatalogThis task explains how to import data from an IDF file, where the component 3Dgeometry is imported from a catalog.

Open the Import.idf document from the samples directory.The .idf file contains the location of the components in the circuit board assembly.

1.

You can use a library and/or a catalog to get a better geometry of thecomponents:

the .lib file contains the 2D footprint geometry of the components.the .catalog contains the 3D (exact) geometry of the components.

However, none of these files are mandatory.

You can choose between several alternatives:open a library only: the 3D geometry is extruded from the 2Dgeometryopen a library and use an existing catalog:

the component exists in the catalog, its 3D geometry isimported from the catalogthe component does not exist in the catalog, it is extrudedfrom the 2D geometry and stored in the catalog if the catalogis not protected (Catalog in read only box is not checked)

open a library and a new catalog: the 3D geometry is extruded fromthe 2D geometry and stored in the newly created catalogopen no library, but a catalog:

the component exists in the catalog, its 3D geometry isimported from the catalogthe component does not exist in the catalog, it is created withno associated geometry

open no library and no catalog, the component has no associatedgeometry.

The Circuit Board Design dialog box opens.

Import with Catalog


The first light is green: the selection is valid.

The second light is red: you need to choose a library.

Browse using the button and select the ImportComps.lib file.The light becomes green.

Workbench IntegrationIn Assembly context, move the components on the board, respecting the constraints.

Launch the DMU Space Analysis to perform a clash check.

Workbench Integration


AssemblyThe integration with the Assembly Design workbench lets you move the componentson the board, provided you are allowed to do so by the related constraints, in thecontext of the full digital product definition.

Refer to the Component Management section for more information.

Assembly


CATIA-DMU Space AnalysisThe strong integration with CATIA-DMU V5 Space Analysis allows you to completethe analysis of the electronic assembly in the context of the full digital productdefinition.

Open the Scenario3.idf file and the corresponding Scenario3.lib file from the\online\samples\circuitboard directory.An Assembly Product document is generated.Then add the existing component (BOTTOM).

Choose the DMU Space Analysis item from the Start menu.1.

Perform a Check Clash using this icon .2.

CATIA-DMU Space Analysis


The Preview window shows the clash:



The analysis reveals a clash. You can:either, change the location of the component respecting thegeometrical constraintsor create a mechanical constraint area taking the clash intoaccount; then transmit the information to the ECAD system in orderto integrate it into the placing/routing algorithm.

For more information about DMU Space Analysis capabilities, refer toCATIA-DMU Space Analysis User's Guide.
