Pads Layout Viewer
Here are several that I find useful. Most of these viewers are designed to run on a PC, but I found one that will run on the Mac platform, which I prefer using. To run PC software, I use the Parallels virtual environment for the Windows OS.

Since we use Cadence tools at work, the Allegro free physical viewer is a very flexible tool with search functions for nets, components and other stuff. The only down side is that you need a three button m
The free visECAD Viewer is a fully functional application for viewing schematic and layout designs in a neutral CCZ format. These files are available natively from the following design and manufacturing solutions:
The whole object is mirrored left-right.For footprints and pads, components on the Top surface move to the Bottom surface, and components on the Bottom surface move to the Top surface.When moving an object or when it is selected, Right click => Select [Move/Rotate/Mirror] => [Mirror](Press the shortcut "M" key)
The whole object is flipped vertically.For footprints and pads, the Top/Bottom changes, and components on the Top surface move to the Bottom surface, and components on the Bottom surface move to the Top surface.When moving an object or when it is selected, Right click => Select [Move/Rotate/Mirror] => [Flip Vertically](Press the shortcut "Shift + M" key)
While maintaining individual coordinates for footprints and pads, etc., components on the Top surface move to the Bottom surface, and components on the Bottom surface move to the Top surface.When moving an object or when it is selected, Right click => Select [Move/Rotate/Mirror] => [Mirror Individually]

It rotates while maintaining individual coordinates for footprints and pads, etc., by inputting an arbitrary angle.When it is a positive number, it rotates counterclockwise, and when it is a negative number, it rotates clockwise.When moving an object or when it is selected, Right click => Select [Move/Rotate/Mirror] => [Individually Rotate Arbitrary Angle]
As an expert PADS Layout user, you'll know that parts form the basic building blocks of design in PADS Layout. Parts are defined as having a part type, a logic family, number of pins, number of gates, and signal pins. The term component is only used when the part becomes placed as a physical object in the PCB layout design.
The Layout Viewer allows you to quickly find the physical location of components, nets and pins on a board. It provides the capability to view layout design data extracted from ODB++ jobs in both XJDeveloper, XJInvestigator and XJRunner.
In this particular example, XJRunner reports that Connection Test has failed, and has identified two nets that are shorted together. By looking at the layout, it is easy to determine that the four most likely locations are the pads on the memory devices. It is unlikely that the fault is under the BGA device as the pins are not next to each other.
Anti-AliasingThe quality of the screen presentation iis strongly improved with the anti-aliasing-technology. Edges are smoothed and the layout is looking much more realistic, even in small zoom modes.
Automatic Ground PlaneThis function fills unused areas of a layout with copper automatically. This accelerates the corroding process and saves corroding material. You may also use this function to create a screen for HF-boards. You can also define thermal-pads on the automatic ground-plane.
Test functionThis function is very helpful to check your layout. You can click on any position of your layout, and Sprint-Layout will find all connected layout-elements, and light them up. This makes it very easy to check the signal flow of the layout.
The AutorouterThere is simple point-to-point autorouter integrated in Sprint-Layout. This autorouter is able to connect two points of your layout. These two points are defined with a connection (rubberband). The autorouter was not designed, to generate whole boards at once. This is usually not possible. To create a proper layout, you have to design it mostly by yourself. The autorouter in Sprint-Layout is designed as an easy to use autorouter. You don't have to make obscure specifications and options. The autorouter is as simple as the whole software.
High resolution and accuracyThe resolution and the accuracy of Sprint-Layout was increased substantially. This concerns also the grid settings and the maximum zoom factor. It is now possible to define a grid-value up to 1µm. So it is no problem to design even very fine layout structures. Also the selection of a special grid-value with the grid-menu is very easy. Just select the desired value from the popup-menu, which is filled with all default grid-values, either in inch or metric values. Of course you can easily extend this grid-menu with your own-defined grid-values. You can change the current grid also with the numeric keys 1-9 on your keyboard. Thes keys are working as hotkeys with predefined grid-values.
The Footprint-WizardThe footprint-wizard helps you to create special footprints for components. You can specify the footprint-type and the parameters and the wizard creates your footprint automatically. Every footprint-type has different parameters. These parameters are displayed and explained in a little picture in the footprint-wizard. All changes that you made will be displayed in the preview immediately. If you have set all parameters, the footprint-wizard creates the footprint and you can place it on your layout.
Properties-PanelThe properties-panel offers the possibility to edit all important properties of your layout-elements without calling special dialogs. Besides you can edit here special properties like positions, etc. The properties-panel responds on the current selection on your layout. Just select the desired element and edit its properties directly in this panel. All changes that you make in this panel will be displayed on your layout immediately, so you can always see the result of your changes. With the help of the multi-selection possibilty, you can even change properties of as many elements as you like at one go.
The SelectorThe Selector is a mighty tool. You can use it to search and select special elements on your layout. So it is possible to search and select all pads with a special shape or size. If the desired elements are selected, they can be changed in common with the properties-panel. The Selector can also help to analyze your layout. So you can list e.g. all tracks sorted by their widths. Such lists can help you to find unwanted elements.
Scanned copiesYou can load a bitmap in the background of your layout. This bitmap can be a scanned-copy from an existing layout. You can use this bitmap as an original to trace the layout. The bitmap must be available as a bitmap file (BMP or JPG). The resolution should be between 300-600 dpi. A pure B/W color depth is recommended, but not absolutely necessary.
PrintingVarious options are available to print your layouts, solder masks, component-mounting-plans, silk-screens or drilling-plans on paper sheets or transparent film. The printout position is adjustable and the tile-option allows you to repeat the printout of small designs in x- and y-direction, to save film and material. The printout can be scaled. All changes you make will be displayed in the preview immediately.
Higher resolution and accuracyThe resolution and the accuracy of Sprint-Layout is increased tenfold. This concerns also the grid settings and the maximum zoom factor. So there is no problem to design very fine layout structures.
SelectorThe new selector is a powerful tool. With this tool you can find and select specific elements of your layout, and edit them simultaneously with the help of the new multiselect-function. For example, you can select and edit all pads with a specific shape or drilling.
Automatic capture modeThis new capture mode makes it easier to place pads or tracks. Whenever the mouse gets close to a capture-point, the mouse will be captured to this point, and helps you to connect exactly. This is particularly very helpful, if some connections are lying out of the grid.
PADS is a PCB design software used for creating board layout, schematics, and for designing the entire circuit. Also, this software helps PCB designers to achieve an efficient board layout. PADS is available in three versions. This PADS PCB design tutorial is ideal for beginners. Also, you will learn how to explore this software from board layout to schematic capture.
To design advanced circuit boards, you can exploit PADS layout capacities regardless of the circuitry. PADS can manage the entire design process irrespective of your design complexity. With the production prep, advanced 3D outline, and physical design re-claim, users can create design much faster. Also, PADS will allow users to complete their circuit project faster.
