Draw a closed contour to specify the size of the PCB. Use the WIRE command and select Layer Dimension (20). Okay, now we can start creating the layout. The Design Rules dialog is accessible through the Edit/Design Rules menu. This includes the most cost-effective DRC values from our PCB services.
Layouteditor drawing download#
You can also download the free EAGLE DRU design rule file: Eurocircuits-EAGLE_dru_18-09-17.zip. They can give you advice on the optimum values for manufacturing all types of PCB.
If you are uncertain what values to use, contact our engineers at Eurocircuits either by email ( or by online CHAT (click on green “Contact support” button). Decide the number of layers your board will probably have and select minimum pad and track sizes, minimum clearance values, minimum drill diameters (for example for vias or micro-vias) and so on. You must then compare board and schematic using the Electronic Rule Check (see Article 2: “Create a project and start drawing the schematic”) and correct the differences manually.īefore you start designing your layout, it’s important to set the Design Rules. If any differences do occur between board and schematic, Back&Forward Annotation stops working.
Layouteditor drawing windows#
If you close one of the windows by mistake EAGLE will warn you with a clear message in the Editor window. But please remember! For Back&Forward Annotation to work you must have Schematic and Layout both open together all the time. Or connect two pins with a net – you will immediately see the corresponding airwire in the Layout. This function transfers each action executed in the Schematic Editor automatically into the Layout and vice versa: Let’s say you add a new component in the Schematic – it will automatically appear in the Layout Editor. The components are already connected with so-called “airwires”, the point to point connections that result from the nets you have drawn in the schematic.īefore you start to arrange the components and create the layout, here is some preliminary advice.įrom this stage onwards EAGLE performs Back&Forward Annotation. Just click on the BOARD command in the Action toolbar of the schematic editor.ĮAGLE opens the Layout Editor window and shows the components randomly arranged on the left of a sample board contour. This page may be outdated.Once you have finished your schematic design, it’s easy to create your layout. If you still missing a function, you are free to write a feature request. The layout handler has all required functions: all basic design functions, all angle elements, boolean operations, macros, font-generator, design rule checker, cross-platform compatible, supported format: GDSII, DXF, OASIS, CIF. These cell is then referred multiple times in the main drawing.īeside the above mentioned design fundaments it is important to have sophisticated functions to handle all drawing elements. This means, that the complete repeating structure only exists once in a single cell. Essential for managing these designs is therefor a hierarchical design. But it can easily be adjusted, if more layers are required.ĭesigns often contain a plenty of repeating structures. By default the LayoutEditor is limited to 128 layers. Additional logical layers are required for describing/naming purpose. For each of these physical layer a belonging layer had to exist in the drawing. The productions of MEMS/IC is done in many layers. This is enough for IC/MEMS which extend usually less than 0.1 meters. With this resolution the LayoutEditor can draw elements up to 4 meters. A higher resolution makes no sense due to atomar structures. The resolution of the LayoutEditor can be set in a wide range and is normally set to 1 nano meter. So a sufficient resolution and a possibility of a high scaling is required. The LayoutEditor™ is a program to design and edit layouts for MEMS/IC fabrication.ĭesigning these layouts require a high precision.
