![]() ![]() To do this, you'll need a 3D model of each component. To design a product like this you need to be able to model the PCB in 3D - so you can visualize the finished board, perform 3D clearance checking, and transfer the loaded board to the mechanical CAD domain. Today's electronic product is compact and tightly packed, comes in an unusual shape, and may well have a PCB that is folded to fit into the case. A PCB footprint is created from a set of standard objects, with the pads providing the connectivity. ![]() IBIS models describe the pin behavior, allowing Altium Designer's signal integrity simulator to analyze the routes.Įach component needs to have a place defined on the PCB where it mounts and connects - the footprint is the model that defines that PCB space. PCB interconnects are becoming part of the circuit as device and circuit switching speeds increase. SPICE models are usually sourced from the device suppliers. ![]() Simulate the behavior of the connected components using the SPICE simulator. ![]() The symbol is created using standard drawing objects, the pins add the electrical properties. The symbol represents the component on the schematic sheet. The following models types can be used: Schematic symbol It is the models that contain the detailed information needed by each design domain. Read more about Understanding Models, Components and Libraries.Įach component is a collection of linked models, and parametric component data. The component that you buy and solder onto the board is the real component, but that component has to be modeled in each of the electronic design domains that you want to use it in.ĭepending on what type of design implementations you plan to perform, your component could include: a symbol for the schematic a simulation model for the circuit simulator an IBIS model for signal integrity analysis a pattern or footprint for PCB layout and a 3D model for visualization, 3D clearance checking and export to the mechanical CAD domain. While it might not be exciting, the components become a valuable resource for your company, and it's essential that they a ccurately represent the real-world component. However, a large part of the work, and to many designers the more tedious part, is creating the components. The rewarding part of product development is coming up with cool ways of solving those engineering challenges, connecting those components to craft your unique design. An electronics design is a collection of connected components. ![]()
