MCAD Collaboration Manufacturing Documentation With all of these elements integrated into a single, all-encompassing interface, switching back and forth between tasks becomes as simple as selecting the appropriate file to work on in your design workspace.
The interface then handles all the rest and provides the design tools you need for the particular task at hand. Our unified PCB design approach has continued to grow and evolve over 30 years of research and development. This philosophy extends not just to the individual engineer, but also to the entire design team. Multiple engineers can all work on different aspects of the same project using the same interface, and no time is wasted translating design data back and forth between design environments.
We hope you enjoy your journey into the world of Altium Designer. Neither the OrCADnor Allegrotranslators are part of the default installation, and must be selected manually. You will then need to restart Altium Designer to complete the installation. It is recommended to use the latest OrCAD file version s available.
The Import Wizard dialog box will appear. DSN file you wish to import. The file will appear as shown in the figure below. Translating Your Schematics It is recommended to keep this box selected, as shown below, so that rectangles are imported properly. The defaults are shown below. Auto-position parameters: This option will override the imported component parameter locations and use the justification settings of the parameter for positioning. Disable "Mark Manual Parameters": If enabled, manually positioned component parameter locations are marked with a visual indicator.
When set to Only Cross Junctions, manual junctions will only be added to 4-way wire junctions. All other junctions will be generated automatically. Translating Your Schematics The default project location for the import process is shown below. The Messages panel may appear, which provides an interactive listing of the error, warning and status messages produced during the import. If the translation process is successful, then the Wizard is complete. You can click to close it and start working on your translated Electronic Schematic designs in Altium Designer.
Schematic Cleanup There will always be at least a little bit of cleanup work to do. This means that the system will place the parameter - including a reference designator - in a default location alongside the symbol body. This is helpful when rotating components, as the system will place the parameters in a neat and readable position.
In an effort to duplicate the source schematic exactly from OrCADCapture, imported parameters have their auto position setting disabled. The reference designators and parameters are then placed as close to their original position as possible, and are now considered manual parameters.
Because of differences in default text styles and sizes, an exact match may not always be possible. The user may want to make slight changes to the parameter text positioning. Parameters that are manually positioned are marked with a small dot as shown below: Manually positioned parameters on a schematic symbol You can choose to handle these manual parameters in one of three ways: Leave the design as-is. Leave the parameters where they are but turn off the dot. Re-enable the Autoposition setting in the Parameter Properties dialog as shown below.
Connectivity Differences In OrCAD Capture, net connectivity is made using net aliases, off-page connectors, hierarchical blocks and hierarchical ports, and globals. Nets between schematic pages within a single schematic folder are connected through the off-page connectors, while the hierarchical blocks and ports connect the nets between the schematic folders.
Altium Designer uses a similar set of net identifiers to create net connectivity. Within a schematic sheet you can use wires and netlabels. Between schematic sheets, nets in a flat design are typically connected using ports, but off-sheet connectors are also available. Off-sheet connectors are purely graphical and do not contain any electrical characteristics. Nets in a hierarchical design are connected from a port on the lower sheet to a sheet entry of the same name, in the sheet symbol that represents the lower sheet.
The Messages panel will report all errors and warnings that indicate hierarchical and net connectivity mismatches. For instance, a Duplicate NetNames error usually points to improper sheet-to-sheet connectivity. Rather than address every possible situation here, we recommend that you familiarize yourself with Connectivity and Multi-Sheet Design within the Altium Technical Documentation.
Complete flexibility is found in all pages of the wizard, giving you as little or as much control as you would like over the translation settings before you commit to the actual translation process. Alternatively, drag your Allegro Design Files into the Projects Panel which will automatically launch the wizard in Allegro Import mode. The following dialog box will appear. BRD Binary or. BRD to the Import Wizard, without a working copy of Allegroon your machine, a warning will be displayed.
Use the Reporting Options page to enable or disable the settings for logging errors, warnings, and events respectively. Open the Log Report after translation in a text editor to examine the details.
Layer mapping can be customized for each of your designs to be imported. You can set your layer mapping once and use this layer mapping for all of your files to be imported. The advantage of this type of batch layer management is that it can save time when importing multiple designs. The disadvantage is that Default Layer Mapping is not always intelligent when it comes to differing structures in designs, so some manual changes may be required. Selecting one of the Altium Designer Layers will present a pull-down that allows the user to change the pre-selected layer.
Right-clicking the layer presents a similar layer list, but also adds the ability first to select multiple layers, and then to change all of those layers at once. This can be helpful if there are large groups of extraneous Allegrolayers that do not need to be converted to Altium Designer at all.
Then right-click on one of the selected layers, and choose Set Selection to Also in the right-click menu is the Invert Selection menu item, which deselects the items that were selected in the Layers list and selects those items that were previously not selected.
This is a handy way to choose layers quickly to map to Altium Designer layers. This allows you to apply layer mapping quickly for Allegroand Altium Designer layers on subsequent design translations. You can change the location if you wish. Each of the imported Allegro Design Files is located in a separate subdirectory in a specified Project Output Directory. PcbDoc in a design project.
A number of intensive tasks, such as loading geometry data, translating nets and components, and generating vias and copper pour polygons, can make the process a bit time-consuming. You can monitor the status bar at the bottom of the Altium Designer workspace to see which operationis taking place at any given time.
Cleanup will be performed on thetranslated document first before you can perform edits on it. The conversion must be run on the Allegro-licensed machine. Translating Your Printed Circuit Boards Circuit Board Design Cleanup Although the translator does an excellent job of accurately converting the PCB data, incompatibilities between the two CAD systems could result in the need for further editing to the imported design.
Allegro uses a separate constraint manager and Altium uses a matrix-based methodology. Design Rules set in Allegro are not currently transferred to Altium Designer. These rules will need to be added manually in Altium Designer. Keepouts Keepout objects have different capabilities in Allegro than in Altium Designer.
In Altium Designer, a keepout can be constrained to a specific layer and can have any physical shape, but it will apply the keepout to all electrical types, be it a via, trace, component pad, etc. By contrast, an Allegro keepout can be configured to exclude specific object types e. When an Allegrokeepout is configured to keep out more than one object type, only one keepout object will be created in Altium Designer.
The type created will depend on which keepout options are set in Allegroand how the Import Wizard Keepout options are enabled. The keepout incompatibilities can also extend into Printed Circuit Board footprints. It is common for designers to include, for example, a keepout area between the pads of an SMD capacitor, which prevents vias from being placed between the pads while still allowing traces.
In the footprint in Altium Designer, you may have a keepout region between the pads. In addition to the keepout checking for vias, it will also flag errors for any electrical item traces, copper pours, etc. In this situation, the Allegrokeepout may translate into an object that could produce unexpected DRC violations. If this situation occurs, then these footprints will have to be edited in the Altium library to remove the keepout. Because thermal connects are, by definition, a design rule in Allegro, this does not apply.
We do not create design rules during the import process to Altium Designer. The only option you have during the import process is to set a global setting in the figure below. In practice, this methodology allows for more efficient thermal setup, due to the fact that all of the settings concerning thermal connections are in one place. If any other specific thermal connection configuration is needed, you will need to create these rules manually within Altium Designer.
One common example is a rule that specifically targets vias for "flood over" connectivity. This is achieved by creating a new rule, and setting the Scope to "IsVia" vs. For more information on design rule creation, please refer to Creating Design Rules. Click Next to continue. Below you see the default Schematic General Options. Select the applicable options.
Translating Your Schematic Symbol Libraries Use the Reporting Options page to enable or disable the settings for logging errors, warnings, and events respectively. The Default Output Library Options are shown below. Change these options as desired. Translating Your Schematic Symbol Libraries The default project location for the import process is shown below. If the translation process is successful, then the Wizard is completed.
