4. Cross disciplinary definition of multidisciplinary object
Complex engineering problems need definitions which require crossing discipline boundaries
Recent engineering objects incorporate closely connected functionality from various fundamental and engineering discipline areas.
Cooperation of disciplines is required in the same engineering task.
Real integration of engineering disciplines in definition of a single model should be realized.
Engineers define multidisciplinary object by cooperation of various disciplines.
Single engineering task incorporates knowledge and skills from several disciplines.
Some basics of cross disciplinary product definition is understood on the example of printed circuit board.

5. Printed circuit design
Electronic circuit definition.
Printed circuit board definition including part placing.
Routing
László Horváth UÓ-JNFI-IAM

6. Printed circuit board definition
Panel behavior is added to shape model.
Physical description of the board and the locations of components placed on the board.
Circuit board geometry is defined in mechanical context
Represented as a tabulated solid in the context of closed contour.
Tabulated solid is recognized as panel.
Full multidisciplinary integration is being established.
Creation and management of electronic part catalogs are inevitable in this area of engineering
Typical conventional solution is data import and export between mechanical and electrical definition using Intermediate Data Format (IDF).

9. Printed circuit board definition – board form features
Board form features can be created before or after definition of the board behavior on geometry.

11. Printed circuit board definition – pattern
Pattern of hole and constraint area.
Often used pattern used for mounting a component
Moving or deleting a component that contextual with a pattern modifies the pattern.
Pattern of Pattern

13. Printed circuit board behavior definition on geometry
Shape behavior
Circuit board behavior

14. Constraint area definition
Spatial and technological constraint areas are defined
Region related definitions in Dassault modeling (representative):
ROUTE OUTLINE : an area where routing electrical connections is allowed
PLACE_OUTLINE: an area where component placing is allowed
OTHER_OUTLINE: other area type defined by an outline, cutouts and a thickness
VIA_KEEPOUT: an area where via placing is forbidden
PLACE_KEEPOUT: a mechanical space reservation where the component height is limited
PLACE_REGION: an area where placing is limited to component of certain types
ROUTE_KEEPOUT: an area where routing electrical connections is forbidden

16. Electrical and mechanical components
Shape model gains electrical or mechanical behavior.
Shape model gains electrical or mechanical behavior.
Technological properties are defined for component:
Resistance
Capacitance
Power
Tolerance
Voltage
Etc.
Mount type is important information: leg mount, surface mount components.

Placing components
Linking the components to the board
László Horváth UÓ-JNFI-IAM

19. Some words about definition of routes
Electrical conductors are needed to connect placed components.
Design rules have to be satisfied in accordance with active element manufacturer specifications.
Simulation for design rules.
Optimization of routes. E. g. Shortest route considering obstacles and design rules.
Different design rules at layers on the board are considered
