21 Planning & Placement 21

22 Placement Challenges With ever increasing design complexity you need to achieve increased productivity during the design planning and placement phase Circuitry with complex topologies requires more in depth planning Efficient communication of engineering intent Organization for the placement of thousands of parts Time to market pressures make reuse a priority! 22

23 Planning & Placement Improve collaboration with engineering Visualize engineering intent Increase designer efficiency Persistent, hierarchical planning groups Easily manage and adjust individual parts or groups User managed netline visualization Organize, protect and reuse circuit groups 23

24 Hierarchical Planning Overview Planning Groups are the heart of the new placement & planning Persistent organization of parts that can be used in all phases of layout Groups can be defined from schematic or within xpcb Groups can be used early to optimize connectivity Group Outlines are available to manipulate all parts in a group Groups are hierarchical Parent-child relationships can be defined through drag & drop Top-down management of the circuitry 24

25 Planning Groups New objects that represent groups of related parts Visualized with symbolic bubbles that indicate combined area of parts Larger circle more space needed to place group Parts and sub-groups can be placed using the RMB Group name Component Sub-Group 25

26 Floorplanning Connectivity between Planning Groups is visualized by netlines Widths signify the amount of connections between groups Thicker line more connections Reorganize circuit groups by minimizing connection length Simple & effective way to drastically improve placement Compared to previous methods, this is a ground-breaking process 26

27 27

28 Placed Groups Placed circuits have persistent grouping Group Outline around all objects Outline dynamically updates as objects are manipulated Manipulate the entire group by selecting the Group Outline Move, Rotate, Copy, Push, Fix Lock actions Freeze Group: allows circuit to be moved but not individual objects Each object now has a Part Ref Des Always fitted within part outline Used as a handle to select parts 28

29 Component Explorer New interface that drives all placement and planning Replaces existing Place Parts & Cells dialog Supports all previous functionality Navigator View allows creation & editing of Groups Placement status icons for Groups List View displays all components within board Extensive filtering capabilities 29

30 Component Explorer Advanced graphical features Cross-probing Component Marking Component Preview Connection Options Place by Schematic Quick access to Spares, Mechanical Cells & Drawing Cells 30

31 Clusters & Rooms Front-end designers can pass design intent onto back-end Add Cluster property to schematic parts User Group will appear in xpcb, including sub-groups Works for Room property too Designate areas of the board where parts should be placed Layout designers can also create their own Groups 31

32 Marking Components User-managed netline visibility in Display Control Between Marked Comps From Marked Comps Allows user to focus on one block of circuitry at a time Mark Groups or specific parts 32

34 Routing Automation 34

35 Routing Challenges Tight design density & exploding design constraints require automation to manage Auto routing can produce low quality results forcing heavy rework Poor support for advanced mfg. technologies demands workarounds 35

36 User-Controlled Automation Routing environment User control Quality (mfg, performance) Complete Digital, analog, flex, rigid-flex High-speed, HDI, embedded Intuitive methods Easy to learn, fast to execute Apply powerful routines with little effort 36

37 Customer Feedback on Routing Performance How much faster do you estimate for the overall routing task? Depending on the design, with many BGA s and large groups of nets, somewhere between 50-60%. I think I personally can get 35-40%. Focusing on routing DDR that previously took days just to route. I was able to complete it in about 4 hours! 37

38 Fanout Patterns Works on multiple components & high-pin count devices Supports SOIC & BGA component types Apply from Fanout Selected button or RMB menu 38

39 Net Explorer Provides quick access to grouping to help organize routing strategies Navigator View displays constraint grouping (read-only) and allows creation & editing of User Groups List View displays nets in the selected group Additional control through crossprobing & marking 39

40 Netline Visibility Netlines are now selectable design objects Visible within Selection List Controlled from Global View & Interactive Selection Additional graphical options in Display Control Dynamic Filtering From Marked Nets Transparency 40

41 Sketch Router Unparalleled speed & efficiency Two Sketch styles Freeform: draw artistic doodle Line: draw straight-line segments Two routing styles Packed: keeps traces together Unpacked: spreads traces out Powerful, yet simple to use 1. Select target netlines 2. Draw Sketch path 3. Hit Sketch Route 41

42 SR Via Patterns Use via patterns to let Sketch Router switch layers Five pattern styles with five rotations each Arbitrary pattern lets software choose Experiment with multiple styles until you receive best results 42

43 Hug Router Supplements Sketch Router use as a post-processor Hugs existing routing when creating a new trace Push & shove traces and vias Free to use any allowable layers and vias 43

44 Real Trace Plow Dynamic Push & shove traces as soon as the clearance gets too small Delayed Waits until cursor hits point where there is no violation performs a single push & shove to insert the trace Both modes available off RMB Mouse up style Mouse drag style 44

45 Active Clearances Displays clearance information in real-time during Plow Adjust circle size and color from Display Control Toggle on & off with RMB Works for Delayed & Dynamic Real Trace Plow 45

46 Prohibit Violations Turns off DRC for Plow Mode temporarily Toggle on & off with RMB Creates clearance violations only when necessary i.e. push & shove cannot place trace otherwise Affects only the area around plowed trace Stipple pattern reminder Use Repair command after 46

47 Phase Tuning Tuning now supports dynamic length matching New CES Phase Tol and Phase Tol Distance Max constraints New Online Hazard: Phase Matching New graphic icon: Diff Pair Phase Match Automatic & Manual Tuning controls Sawtooth Pattern parameters in Editor Control 47
