Ok so if you use Hierarchical Sheets to add multiple instances of the same schematic block, you will obviously get duplicate designators on your pcb layout. Typically, you set up the design rules at the start of the design process and then verify that the design complies with the rules at the end of the design process. It is optional if you want to check the Create Project Folder, which will create a subfolder in the target location with the project name.

For example, the software removes ports that are unconnected or driven by GND or V CC during synthesis. In the hierarchical approach, you have a main design or top sheet, that contains block symbols representing all the subcomponents of your design. Therefore, users often carry out simple (schematic) schematic design instead of second thinking about the project organization. a net and it's signals in a hierarchical design, several commands cannot be: executed in the board and have to be done for the correponding part or net: to be annotated to the elements or signals it relates to. That is, classification is similar to the concept of classes in cpp.Each of the child schematics can in turn contain This limitation is only for entities within a hierarchy and if there is: consistency. The term 'design reuse' is much touted in the field of electrical engineering.

It’s that time of the year again, and we’ve got a major update planned for Altium Designer.

Trace the net back to the incoming/outgoing port on each sheet and ensure the names for the ports are made the same. ) However the entry/port name is arbitrary (doesn't need to match even if this is a good practice to keep you sane) and the only way it knows the port is related to the bus is because they touch graphically. The G2L will be near the Top Copper Layer, and G3L will be near the bottom layer.Altium hierarchical design duplicate net namesĪltium Designer. To correct this, simply rename the layers using the G2L and G3L extensions. Unfortunately, this makes it impossible for us to determine the correct layer order, since multiple layers identify themselves as “Internal Layer 1”. If you’re using a 4 layer stackup with both “power” and “signal” internal layers, Altium will generate the internal layers as GP1 and G1. Some format issues in METRIC are more difficult to reliably correct. Try exporting the drill file with the INCH units.

Make sure any uploaded zip files include this file. Common Issues Missing Drill FileĪltium keeps the drill data in the project-name.TXT file. See our guide for limitations and DRC requirements of slots. SlotsĪltium’s native Slot callout is supported. If the drill files do not appear correct, check out our Drill File CAM configuration page for settings that we know will work correctly. Drillsĭrill files should work without issues for most export options. This layer can also contain board cutouts.įor best results, place the outline by itself on the Keep Out, or on a Mechanical Layer (normally 1 or 2). This tells us where the fab should mill the edges of the board. We need a watertight board outline on its own layer with no extra text or measurements. See our Positive vs Negative Gerbers page for additional information. We recommend submitting planes with a Positive polarity.

See Altium’s Gerber Setup for information on how to access this setting. When these footprints are added to copper layers, it can create gerbers that will be fabricated with shorts. Many footprints contain mechanical “courtyard” or “pick and place” data on these layers. The RUL file currently shows the older 13mil drill and 6mil ring Generating Manufacturing Filesįor accessing the various menus and output screens, see Altium’s Gerber Setup Disabling “ Mechanical Layers to Add to All Gerber Plots”Īltium tools have the option Mechanical Layers to Add to All Gerber Plots, which must have all layers unchecked. Known issues: Current minimum 2 layer specs are 10 mil drill hits, with 5 mil annular rings. If you have corrections or find errors, please email support. Use your judgment and always verify your designs meet our service specs to prevent design defects that could affect your boards.
