  1. Summaries on Using MentorGraphics Module 2-15 MentorGraphics training HW/WTD/MCG Apr. 17 2006

  2. Module list: • Module 2: Design Input • Module 3: Create Board Geometries • Module 4: Creating Parts • Module 5: Packaging the Design • Module 6: Interactive Placement • Module 7: Using Board Station RE Placement • Module 8: Design Rules • Module 9: Routing • Module 10: Using Board Station RE Routing • Module 11: Area Fills • Module 12: Artwork and Drill Data • Module 13: Manufacturing Drawings • Module 14: Board Design Process Review • Module 15: Handling Changes

  3. Module 2 Design Input • 1. Create a project directory • 2.Open sheet symbol hierarchy • 3.Add properties to a schematic • 4.Open property reports • 5.Check schematic sheet for errors and save it

  4. Module 2 Design Input • 1. Create a project directory project lead engineer/located on a server/regularly backup *Not create the actual MGC design database directories Location Map/ check reference.

  5. Module 2 Design Input • DmgrDAOpen SheetModule 2Lab design sheet1

  6. 2.Open sheet symbol hierarchy • DmgrDAOpen SheetModule 2Lab design sheet1 • Select objectReportObjectSelected(all/instance/net) • Instance • Net • Instance Required Properties • Comp • Ref • Pin • Pin-no • (Placement_Region/Swapping) • Adding Wires and Properties

  7. 3.Add properties to a schematic 1.Right click/File pulldown/double click/middle stroke (starting inside instance)

  8. 3.Add properties to a schematic

  9. 5.Check schematic sheet for errors and save it

  10. The summary of Brd_arch for Schematics Main Steps • List part no. of every component used in design. • Set a new viewpoint and then open new sheets in BA. • Add symbol instances by part no.. • Add wires to complete necessary connections. • Name net of symbol instances. • Save without any error.

  11. Set a new viewpoint and then open new sheets in BA

  12. Add symbol instances by its part no.

  13. Add wires to complete necessary connections Add Bus/Bundle Add wire

  14. Name net of symbol instances

  15. Save without any error

  16. Module 3 Create Board Geometries • 1. Define four different types of layer categories • 2. Define the function of the Board geometry • 3. List the attributes that define a Board geometry • 4. Explain how attribute settings control PCB design behavior

  17. Module 3 Create Board Geometries • Board geometry is the definition of the printed circuit board on which you place components and route trace. The board geometry defines the dimensions of the board, the area in which components are placed,and the area in which routing is allow. • LIBRARIAN is a unique PCB tool in that it does not require any input data.

  18. Module 3 Create Board Geometries

  19. Drawing the Board Outline 5.ShapeADD LINEVertices Command: add li Note: The board outline needs to be one continuous path • layer:BOARD_OUTLINE • SetupLine width • SetupGrid • Grid Snap Off

  20. Add a Slot –Trim--Chamfer ShapeAdd lineSlot TRIME/EXTEND Change Entity TypeSegment Add lineChamfer

  21. Adding the Placement Outline—on the Place layer • The placement outline defines the area in which LAYOUT places components. LIBRARIAN display the placement outline on the place layer and stores the outline coordinators as the Board_placement_outline attribute. • Interactive • Automatic From Palette/cre pl o

  22. Adding the Routing Outline—on the Signal layer • The routing outline defines the area in which LAYOUT can route traces. LIBRARIAN display the routing outline on the Signal layer and stores the outline coordinators as the Board_routing_outline attribute. • Interactive • Automatic From Palette/cre ro o

  23. Adding Drill Holes—on the Drill_Holes layer • ADD DRL HOLE/ add dr h

  24. Adding the existed Geometries • GeometriesList Geometry Librariesview Read • ShapeFix component/Unfix compnent/ fix co/ unfix co

  25. Checking the Board Geometries and Saving • CheckGeometryActive Geometry (see report , errors) • GeometriesList Geometry Librariesview Read (library hierarchy) • FileSaveDesign All

  26. Module 4 Creating Parts • LIBRARIAN is a unique PCB tool in that it does not require any input data. • LIBRARIAN is also a tool for creating component geometries • Create component geometries • Assign part numbers • Map symbols to part numbers • Map logical pins to component pins • Verifying components are error free

  27. Component Geometries • A component geometry is a geometry that has one or more pins for electrical connection. There are the electronic items like resistors, SMD components, and switches that are place on the printed circuit board. • The component geometry defines the location and identification of the pins on the device, the type of pads, and the actual physical size and shape of the geometry. A picture of the device for an assembly drawing and the silkscreen image might also be included. • Location and identification of the pins • The type of pads • the actual physical size and shape • The picture of an assembly drawing • The silkscreen

  28. Completing the Create Component Dialog Box Must define the default padstack firstly

  29. ADD pins/component outline/place outline/REF/check&save 1.Add PIN ARRAY on the singal_1 2.Add component outline on the silkscreen 3. Add place outline on the place 4. Add REF on the silkscreen 5.Check geometry and save

  30. Activating a Catlog 1.CatalogsList Catalogs…Read 2.Creating a Part Number 3. Mapping the Symbol to Part Number 4. Add Power-Pins 5.Mapping Pins to Component Pins

  31. Mapping the Symbol to Part Number 3. Mapping the Symbol to Part Number Symbolslist symbols Librariesdesignviewclock805Map to Part Number Change Part NumberSymbol comp Property

  32. Mapping Pins to Component Pins& Checking &Save 4. Add Power-Pins 5.Mapping Pins to Component Pins

  33. Module 5: Package the Design

  34. Creating a Packaging configuration file Setup Design RulePkgconf

  35. Reading catalogs into Package Invoke PACKAGE CatalogsList catalogsDesignRead

  36. Initiating Automatic Packaging Build

  37. Modifying Reference Designators SelectAll lines ChangeReference by range

  38. Resolving Geometries and Save GeometryResolve Geometry FileSaveDesign all

  39. Librarian Main Steps for Creating Board Geometries • Create board • Drawing board graphics • Adding drill holes • Placement & routing outlines • Check and Save without error
