Component Alignment  Introduced in 16.3  Placement App Mode  Enhanced in 16.6 to support  Alignment Edge of component   

Bottom or Top if aligned Horizontally Left or Right if aligned Vertically Placebound shape used as alignment object

 Equal spacing between components  Use DFA spacing for min compression  Increment/Decrement controls to adjust

spacing during dynamics

Before alignment

After alignment with DFA compression 3

Parameterized Rectangular Shapes  Shape – Add Rectangle command

enhanced to support …  Pre-defined Width and Height values 

Aligned with “Place Rectangle” option

 Corner style options   

Orthogonal (default) Chamfer Round

 Corner length options  

Trim or chamfer length As a percent of the shorter edge

4

Moving Elements outside Class Structure  Popular CCR enhancement now

permits certain elements to be moved outside of present Class/subclass structure  Elements limited to lines, line segments, text & rectangles  Supported in General Edit Application Mode  Hover over element then use RMB to access Change Class/Subclass command

5

Snap Updates  The ‘Snap Pick to’ command has been

enhanced with the following RMB options …  Rectangle Edge Vertex  Rectangle Edge Midpoint  Rectangle Edge  Shape Center  Symbol Center

 ‘Edit-Vertex’ command is now integrated with

the snap function.

6

Symbol Editor – Import .csv  The Symbol Editor now supports both exporting and importing of pin

based .CSV files.  The format of the file supports <pin number, padstack name, x position, y position, rotation, text offset x, text offset y, text rotate, mirror>

7

Offset Routing • •

Add Connect now supports Route Offset Angle Application usage -

-

•

Fiber Weave offset routing where the orientation of the trace with respect to the glass weave determines the amount of skew seen Connector breakout

New Slide function now maintains routed angle

8

Auto-Interactive Convert Corner  Available through Unsupported

Prototype menu  Designed to convert corners on  Single Nets/Diff Pairs  Tuning Patterns  Off Angle Routes

 Primary usage  Convert 45 corners to Arc  Convert Arc corners to 45

 Use Min and Preferred settings

to control corner

9

Line Width Retention during Add Connect  Currently, user line width overrides are permitted

during Add Connect but are reset back to constraint driven when the command is completed.  New behavior in 16.6 maintains user setting until manually reset  A Line Width override now appears in blue; similar to the model established in the Constraint Manager worksheets  User can easily reset to constraint mode by selecting “constraint” from the drop-down menu

10

IPC-2581 Overview  A single XML formatted file for the

output of manufacturing data  Replaces multiple files, Artwork, NC Drill,

IPC-356, test, etc.  Support for 

IPC-2581 Amendment 1



IPC-2581 Rev. A

 Open/Public format  Managed by IPC and it’s members

 Export IPC-2581  Import IPC-2581  Artwork data only

 Compare tool

11

Associative Dimensioning Updates  Support for Overriding Computed

Dimension Text  %v when entered in the text field will be

substituted by the computed dimension value  %u when entered in the text field will be substituted by units of IN or MM  Click on “?” for format examples

 Balloon Dimensions 

Instance parameter support for specifying different geometries

12

Generic Tech File Support  New tech file export option “Generic”  Designed to be a Cross-section neutral file  Hierarchical layer mappings Top  Internal Signal  Internal Plane  Bottom 

 Import into a “N” layer board 

Cross section not impacted

13

Auto Interactive Phase Tune Update • Phase Bump options now include

“Accordion” style • Default style remains “Sawtooth”

High Speed Option

Auto-Interactive Delay Tune Update • New “Exclude Smart Critical” Control - Enable this option to exclude the longest

(critical) net in the “Smart timing group”

- Currently users have to be careful not to

select this net during the AiDT command.

- With this option enabled, one can select the

entire byte lane and not worry about impacting the longest signal.

High Speed Option

Automated Tuning Bump Removal • Automated method to remove

Tuning and Phase Bumps • Invoke new “Remove Tuning” command  Formally known as Detune through

the Unsupported Prototype stages of development

• Select option(s)  Remove Tuning Bumps

 Remove Phase Bumps

• Selection Set can be  Single net  Diff Pair

 Group of nets or Diff Pairs

• Object Selection  Cline and Cline Segment

High Speed Option

Find by Query • New Relational Query Engine designed to filter elements based on qualifiers and operations (AND, OR, NOR) • Currently available as an “Unsupported Prototype” in QIR6 • Invoke Show Element command then select “Find by Query” • Filter results to view area in canvas

New Drafting Commands • Relative Move & Copy - Move & Copy elements about a userspecified axis

• Current suite of Unsupported

Prototype Drafting functions
