The other point to note is the 2 highlighted selections at the bottom. 4|Pageįigure 4: Summary for Layout Updates You can see in Figure 4, there is a list of all of the components, rooms and wires we created in our schematic. In most cases, this step is after you have finished schematic layout completely. It is suggested to only import into your design when you are ready to do some layout with parts of your schematic that are not expected to change. The first time this is done in a design, the list is quite long. This window represents all of the new components or changes to your schematic that you would like to import into your PCB design. This will then pop up the Engineering Change Order Window seen in Figure 4. Do this by clicking Design->Update PCB Document. The design we will be building is seen in Figure 1 and Figure 2.įigure 2: Example Circuit (2/2) Now that you have working design, import your design into your PCB layout document. Before proceeding, double check that each of your components in your design have the correct footprint. We will use the example from the Altium_Schematic_Tutorial.pdf file to continue this portion of the design. Importing your Design from Schematic to Layout Before you start your layout, you need to have a complete and errorless schematic. 22 Figure 28: Silkscreen Over Component Pad.

You will soon see that setting even the most complicated rules in Altium Designer is incredibly easy and clear. You can access the PCB Rules and Constraints Editor dialog at any time your PCB is open by selecting Design > Rules from the main menus. The rules in Altium Designer are set up using the PCB Rules and Constraints Editor dialog, which is a modern and powerful tool for design rules management. Rules in Altium Designer are presented in the form of a hierarchy - from the fundamental rules covering the entire board to the rules of individual net classes. Any mistake or failure to comply with the rules can lead to problems, up to and including the complete inoperability of the PCB or the impossibility to manufacture or assemble it. These rules cover everything from the minimum width of the conductor to the maximum height of the component in a particular area of the PCB. These rules describe to CAD the restrictions for manufacturing, impedance control, and routing parameters, and what can and cannot be done within the design. Correct rules definition is a very important step in the PCB design process.
