IPC 2581 Stackup Exchange

The ability to import stackup data using IPC-2581 data has been introduced in 16.6 QIR 6. Defining a stackup for controlled impedance and other critical performance requirements are carefully created to be transferred by a spreadsheet, document image, or other paper form. This data is manually specified into the Allegro board stackup definition where the potential for human error is a concern.

Stackup exchange enables electronic transfer of stackup data through the IPC-2581 format. Stackup analysis tools can define the stackup structure based on performance analysis, and then export that stackup as IPC-2581 data. That data is used to import into the Allegro PCB Editor. The imported stackup may represent a designer’s view, or the actual manufactures view with multiple build up to create a core layer or needed dielectric thickness.

Allegro also provides the ability to export only the stackup in IPC-2581 format to pass to fabrication and analysis tools to be used to determine if design criteria are met; cost and manufacturability.

■ Dynamic Rat Suppression on page 18

Auto Interactive Breakout Technology (Design Planning Option)

AiBT is an auto-interactive command designed to expedite the breakout of high pin count devices like BGAs and Connectors. It operates on a user-defined selection set of Interconnect Flow Planner Bundles or the Bundle's rats as its input. This input is used to define a pattern that tries to create the optimum channel utilization and layer distribution possible while intelligently sequencing the breakout routes at each end so not to create cross-overs when routing the trunk.

Additional user-controls that influence the breakout pattern include:

■ The Bundle's layer properties whether defined by layer-sets or user-choice on the Bundle's layer properties.

■ A Rat sequence can be created, edited or defined to create a specific entry/exit pattern for the Bundle. The Rat sequence can be used to define the exact pattern desired for both ends of the Bundle to implement.

■ The location of the Bundle's Gather Point is the angle of its placement relative to its associated pins/vias and how far from these pins/vias will determine how far the breakout will be from the pins/vias it starts from.



■ You can also decide if you want both ends of the Bundle broken out at the same time or just one end; the end closest to where the cursor was when the command was invoked.

Edit Vertex – Snap to 45

The Edit – Vertex command now supports a new Snap to 45 option to snap off angle routes onto 45 degree angles. This may be useful after moving components with the Stretch etch option enabled. Often the results of this action produce routes on undesirable angles.

Note: The CTL key can be pressed to toggle the behavior.

Remove Tuning (High Speed Option)

The Remove Tuning command automatically removes standard tuning bumps and phase bumps from cline routing. You can interactively select clines or cline segments and the command identifies appropriate bumps and removes them from the cline, leaving the rest of the cline routing unchanged. The Remove Tuning command increases user efficiency by quickly removing timing and phase compensation, to allow easier modifications to the routing.

Dynamic Rat Suppression

When manually routing, you may wish to hide all rats to improve visibility as it relates to your routing path. Selecting the Add Connect option Auto-blank other rats will temporarily blank



all rats during the Add Connect command. Upon completion of the connection, all rats are re-displayed.

All Rats Displayed Dynamic Rat Suppression



Productivity Enhancements

■ Drafting Updates on page 21

■ Dimensioning on page 22

■ File Locking Update on page 22

■ Find by Query on page 23

■ Unsupported Prototype Functionality on page 25

Split Views

The Split View technology is a new capability that was introduced in 16.6 QIR 3 and allows you to view another area of the design canvas, while still working with the standard main editing canvas. This technology is extremely effective for breakout routing solutions, where the user can now visually see both end of the bus/interface and make decisions/edits to both ends at the same time.



Move Component with Slide Etch

The Move command has been enhanced to support a new Slide Etch option. When moving components with attached routes, the desire is to maintain the segments on octalinear angles. Prior to this release, the Stretch Etch option was the common method for moving routed components. However, the results were not desirable and required manual edits to restored the intent.

Drafting Updates

Two new commands have been added to the suite of drafting commands introduced over the 16.6 QIR releases:

Extend Segments

This command allows users to extend line and arc segments to a projected intersection point. When invoked from the menu, the user is prompted to Select object to extend. After an object is selected, the user is then prompted to specify another object with which the first object should intersect. Once the second object is selected, the two objects are temporarily extended and highlighted to show the possible intersection points.

Trim Segments

This command allows users to remove portions of line and arc segments that extend beyond specified intersection points. When invoked from the menu, the user is prompted to Select object to trim. After an object is selected, the user is then prompted to select another object intersecting the first. At this point, the user is prompted Select side of segment(s) to trim,



after which one or both objects can be trimmed by making successive picks on either object to one or the other side of the intersection point.

Dimensioning

A Mirror Text command has been added to the Dimensioning main menu.

File Locking Update

Expiration duration field now support user-definable entry in days; previously limited to 14, 90, 180 and 365 days. A new option NTP time service has also added that uses NTP



(Network Time Protocol) server to verify time. Otherwise system time is used to check for expiration.

Find by Query

A Find by Query unsupported prototype command is now available within Allegro PCB Editor. It is invoked by clicking on the Find by Query button at the bottom of the Find portion of the mini-status dialog. The principal function is to allow users to locate and pre-select objects that meet any of a number of criteria. Once objects are preselected, user can hover over them and right-click the mouse to access any number of relevant application mode commands.

The command flow is as follows:

■ Choose type of object to locate

■ Establish find criteria

■ Add candidate objects to the preselect buffer



When first invoked, the dialog appears as follows:

■ The Objects to Find section of the dialog allows users to specify the type of object to locate.

■ These are grouped by type within each tab, and clicking a radio button changes the object type presently under consideration.

■ The Find Criteria section allows users to establish query criteria to filter which object instances make it into the Candidate Objects section.

Examples

The following figure shows an example to find all pins that use padstack PAD19.



The following figure shows an example to find/highlight all GND Pins on U100.

Unsupported Prototype Functionality

PCB Editor Users are reminded of functionality that is currently in a prototype state but mature enough for use in production. The suite of commands is available in the Unsupported Prototype menu under the Edit, View, Route and Manufacture menus. Help document access is conveniently located on the last row of the menu.

■ New Package Integrity Checks for Wire Bonding on page 30

■ Aligning and Respacing Pins in Symbol Edit Application Mode on page 32



New Package Integrity Checks for Wire Bonding

Two new rules are now available for wire bonding to check pad wire offset and pin wire count, Pad Bond Wire Offset(F) and Pin Bond Wire Count, respectively.



■ Pad Wire Bond Offset (F): This rule checks that wires are connected to the center of a pad ensuring proper connectivity during manufacture. The check can also correct any errors, if you select Fix errors automatically (where possible).

■ Pin Bond Wire Count: This rule checks that wire bond pins requiring a specific number of connection have the right number of connections. The rule checks the WIRE_COUNT property of pins to determine the number of connections required. This rule checks only pins with the WIRE_COUNT property set and counts bond wires connecting to objects further down the diestack/substrate.

For more information, see the descriptions in the Package Design Integrity Checks (Tools – Package Design Integrity) window or refer to the APD and SiP: Using the Package Design Integrity Tool section of the Managing the Database chapter in Allegro User Guide: Getting Started with Physical Design.

Project Directory Structure (DE-HDL Environment)

FSP provides an addition option to create a new project. You can now create a new project from an existing project file (.cpm). A new project file (.fsp) is created at the following location <project_name>/<project_name>_lib/<project_name>/fsp.

In addition, a new project directory structure is introduced. When you create a new project for the DE-HDL environment, the following files and directories are created:

■ A project file (<project>.cpm)

This is a DE-HDL project file.

■ A cds.lib file

The cds.lib file contains the DE-HDL symbol libraries which you can use in FSP.

■ fsp_fe_lib

fsp_fe_lib is a local directory and contains DE-HDL symbols generated by FSP.

■ A <project_name>_lib directory

This directory stores the design you capture in FSP in the <project_name> subdirectory, which is referred to as a cell representing the entire design or a part of it.

The cell (<project_name>) contains a set of subdirectories called cell views. By default, fsp is the only cell view present in the cell. It stores the following files and folders

❑ <project_name>.fsp

❑ <project_name>.log

❑ master.tag

❑ lrf

❑ output

When you generate a schematic, all the schematic files are generated in the <project_name> directory.

Note: For detailed information about the files and directories, see the Project Creation and Setup chapter.

Additional Enhancements

Significant enhancements have been made in the following sections:

■ You can now recover recent changes made in the editors or canvas by using the Undo command. To reverse an undo operation, you use the Redo command immediately after using Undo.

■ The new Canvas Status Bar provides you a quick way to access information about a pin and a net present on the Canvas. For example, when you hover the mouse pointer over a pin, the Canvas Status Bar shows the name of the pin on the left side (Pin:). However if the pin is connected to a net, the net name is displayed on the right side (Net:). You can also hover the mouse pointer over a net to access pin and net information.

■ The Do Not Connect property support is extended to the Virtual Interface component. You can now specify the Do Not Connect property on a Virtual Interface’s pin. A pin with the Do Not Connect property cannot be used for making connection.

■ A new option, Allocate Pair Pins Together is introduced in the Process Option Editor dialog box. Use this option to connect all the single-ended pins of a interface to the available differential pair pins on a device, before connecting differential pair pins to the available differential pair pins.

■ You can now apply fixed internal connection type and fixed external port type on all the pins of FPGA. For detailed information, see the Working with Termination chapter.

■ You can now generate .xdc files and Vivado TCL scripts for all the Virtex 7 devices. An XDC file stores the design constraints and TCL commands generated by FSP. You use both the XDC file and TCL scripts to implement and synthesize the design in the Vivado tool.

PSpice Part Search Symbol Viewer

Now, you can view the symbol of a part selected in PSpice Part Search before placing the part on the schematic.

If you select any category or library folder in the Category View, symbol of the first part in the folder will be visible in Symbol Viewer.

Note: Only one part can be selected at a time.



Enhancements in Learning PSpice

A new book called PSpice Advance Analysis is available in Learning PSpice. This book explains various Advance Analysis options used in PSpice Advance Analysis, such as Sensitivity and Optimizer, using design examples.

Note: You can access Learning PSpice in the Capture–PSpice flow only. To access Learning PSpice, choose Help – Learning PSpice in Capture.



Enhancement: Pin Names and Pin Numbers Behavior on Part Rotation

Prior to 16.6 QIR 6, the pin names and pin numbers of a pins on the left and right sides of a part retained their default positions in Capture on 180 degree rotation of the parts. For example, if a part had the pin names and pin numbers above the pins before 180 degree rotation, the pin names and pin numbers continued to be displayed above the pins after 180 degree rotation.

Similarly, the pin numbers of the top and bottom pins of a part are displayed on the left side of the pin. In the following figure, you can notice that the pin names and the pin numbers retain their default position even after 180 degree rotation of the part.

Now, with the movement of pin names and pin numbers being supported on the pins from 16.6 QIR 6, Capture still retains the default behavior of the pin names and pin numbers during part rotation.

It maintains a relative offset of the pin numbers and pin names, and the direction of the pin numbers and pin names with respect to the pins of the rotated part. For example, if the pin number or pin name has an offset above the pin before 180 degree rotation, the same offset will be retained for the pin number or pin name above the pin after 180 degree rotation. In the following figure, you can see that Capture retains the default behavior of the pin name after part rotation.



Note: If you set the SetOptionString DoNormalRotationForPinNameNumber TCL option to TRUE, the position of the pin name or pin number relative to the pin will not be maintained. For example, if the pin number is placed above a pin and you rotate the symbol by 180 degrees, the pin number will be below the pin after rotation.



Enhancement: Specify Pin Spacing in New Part from Spreadsheet using INI Options

Now, using INI options, you can specify pin to pin spacing; start and end margin space; and the default width and height of the bounding box for a new part from a spreadsheet.

Following are the descriptions of the new INI options, which are set using a TCL command:

■ GeneratePartPin2PinSpace

This INI option specifies pin to pin spacing and can be set using the TCL command. For example, to set pin to pin spacing as 2 grid units, enter SetOptionString "GeneratePartPin2PinSpace" 2 in the Command Window.

■ GeneratePartStartEndMargin

This INI option specifies the start and end margin of the left, right, top, and bottom sides of a part. For example, to set the start margin and end margin as 2 grid units, enter SetOptionString "GeneratePartStartEndMargin" 2 in the Command Window.



■ GeneratePartMinHeight

This INI option specifies the default height of the bounding box of a part. For example, to set the default height of the bounding box of a part as 5 grid units, enter SetOptionString "GeneratePartMinHeight" 5 in the Command Window.

■ GeneratePartMinWidth

This INI option specifies the default width of the bounding box of a part. For example, to set the default width of the bounding box of a part as 5 grid units, enter SetOptionString "GeneratePartMinWidth" 5 in the Command Window.

Note: Use integer multiple of the grid unit to specify the value for these INI options.
