In this introductory article we will investigate the various techniques available for copper routing in NI Ultiboard, how to use them, and when to use them. Back to Top. 2. Routing of Copper Traces. In Printed Circuit Board PCB design, there are three fundamental tasks that allow you to prepare a board for prototype and manufacture. First the board outline must be created for the form factor of the design. Second in consideration is part placement. Polaris Centurion Indy 1981 Workshop Repair Service Manual Document about Polaris Centurion Indy 1981 Workshop Repair Service Manual is available on print and digital. With the integrated capture, simulation and layout environment of the National Instruments Circuit Design Suite, engineers have a complete PCB design and validation. Cda Manual' title='Cda Manual' />In part placement various landpatterns or footprints of design devices are configured on the board. Each placed part consists of pins which are terminals that need to be connected in order to complete the design. A PCB design tool represents the necessary connections between parts with a wire. These wires are called nets. Navy Notre Dame Game'>Navy Notre Dame Game. Therefore the third fundamental task in board design is to route these net connections between various parts. The routing process turns these various net connections into copper traces which connect parts in the physical prototype with current carrying connections. The net acts as a design guide indicating that two pins must be connected, while the copper trace is the actual physical connection which will be made as a part of your PCB.

NI Ultiboard allows you to define copper traces using a number of different methods. Each method provides varying degrees of control that allow an engineer to balance precise copper definition with automated speeds in order to effectively design a PCB. The routing methods available to engineers are Manual Trace Placement. Using the FREE TDM Excel Addin for Microsoft Excel, you can load and work with TDM and TDMS files in Excel. Supported Features Interactively loads TDM and TDMS. Follow Me Router. Connection Machine. Autorouter. In this article we will investigate how and when to use each of these routing methods. Back to Top. 3. Getting Started. To assist in the steps outlined in this article, we will use the attached example file to practice routing. Download the attached 6.

Select File Open. Browse to the desktop where you saved 6. ExampleDesign. ewprj. Click on the Open button to view the file as seen in Figure 1 below. Figure 1 6. 88. 0ExampleDesign. Follow the next steps to ensure that your work area is correctly setup Notice that on the left side of the NI Ultiboard screen you have the Design Toolbox if you cannot see this currently you can view it by selecting View Design Toolbox. On the bottom of the Design Toolbox select the Layers tab. Whenever you are placing copper routes in the work area you must first select the layer upon which the route will be defined. In this example we will be using the Copper Top however any of the copper layers Top, Bottom, Inner can be selected in the Design Toolbox. Crack Tsuki Possession. Double click on the Copper Top layer in the Layers tab it will now be highlighted in red as seen in Figure 2 below. You are now ready to draw routes upon the top copper layer. Figure 2 Design Toolbox. Back to Top. 4. Method 1 Manual Trace Placement. What is Manual Trace PlacementPlacing traces with the line drawing tool allows the user to completely control every aspect of a copper trace. This drawing tool follows your mouse cursor and creates a copper route according to your exact specifications. Other than following your mouse it is important to note that since you have complete design control you must be careful not to create routes that will cause design rule errors or put into questions the validity of your design. This means that sharp or obtuse angles in your routes should be avoided that will cause you to lose signal integrity. When to use Manual Trace Placement. The manual trace placement is recommended when you have a part that requires a very specific routing, particularly when you have a surface mounted connector with a high pin count, FPGA or very restrictive spacing between adjacent pins, the manual trace tool will give you the needed accuracy to properly define your route. Other methods such as the autorouter discussed later in this article may not be able to mathematically define how to route suitably in these situations. How to use Manual Trace Placement. In this example we will make a manual connection between part C1. R1. 2. To use the manual trace placement tool In Ultiboard select Place Line. With the mouse left click once on the top pin of part C1. Figure 3 Component C1. As you move the mouse away from the pin you will notice a neon green connection trail your movement. Move your mouse in the direction of the net connection between C1. R1. 2. To place a pivot point for your copper route, left click with your mouse anywhere in the black work area of your design. You have now defined the placement of this segment of your design as seen in Figure 4Figure 4 First routed segment. To create an orthogonal section to a copper route, you can simply click on the SPACE BAR on your keyboard, and Ultiboard will automatically create a route that is exactly 9. Click on SPACE BAR again to exit orthogonal mode. Complete the route and connect C1. R1. 2 as seen below in figure 5, by using the SPACE BAR to create the orthogonal route. Figure 5 Manual Trace Placement Routing. Back to Top. 5. Method 2 Follow Me Router. What is the Follow Me RouterThe follow me router adds to the functionality of the manual trace placement tool, with Ultiboard beginning to make some design decisions on your behalf. With the follow me router, your mouse again defines the shape of the route however Ultiboard will automatically suggest pivot points and the route between two pins, with a light blue trace connection. Also if your route must be narrowed at all to make the connection appropriate to get between pins etc, Ultiboard will automatically narrow your route. When to use the Follow Me Router. The follow me router is an appropriate tool when you need some guidance on how to connect two components but still want to be able to define the route, pivot points etc Generally if you do not need precision of manual placement, but would like assistance in creating traces which do not conflict with good design practices sharp angles etc then the follow me router is an appropriate tool. It would still be recommended to use manual trace placement for high pin density chips and FPGAs. How to use the Follow Me Router. In this example we will make a follow me router connection between part C1. C7. To use the follow me router placement tool In Ultiboard select Place Follow Me. With the mouse left click once on the bottom pin of part C1. Notice that as you move the mouse a light blue connection guide appears between the two pins figure 6. This is an Ultiboard suggestion for routing. Figure 6 Ultiboard Trace Guide. Continue to move the mouse towards the pin of C7 and notice that pivot points are automatically placed in your design. To add your own pivot points, simply left click once anywhere in your design. Complete your connection between C1. C7 figure 6Figure 7 Completed Follow Me Route. Back to Top. 6. Method 3 Connection Machine. What is the Connection Machine Again we continue to build upon our more manual processes manual trace placement, follow me router with the Connection Machine. The Connection Machine can be considered to be a subset of the autorouter. The connection machine automatically defines a route, but does so, on a net by net basis, with a minimal amount of user intervention to customize the route.
