LINKING SNIPPETS WITH A SCHEMATIC EDITORĪfter you have created the schematic circuitry snippet along with the Printed Circuit Board layout snippet containing matching unique designators and placing them in both the schematic and PCB components, you need to link them together using the Project Component Links function.īy default the ‘Designator’ checkbox is checked, allowing you to quickly match the components. Verify Proposed Changes in the Designator columnįigure 2: Continue with Accept Changes to set the new reference designators. Next, click on the Update Changes List and continue (see Figure 2). When you are finished, you have created the snippet of both the schematic circuitry and the PCB layout.įigure 1: Set the Designator Index Control to the number you want to begin with. Once you have circuitry in the schematic with a unique set of designators that will not potentially be used in any of your designs, update the PCB design and proceed to lay out that circuit using unique designators. Enable the check box in the Designator Index Control section and enter a very large value. To do so, enable the Designator Index Control section of the Annotate Schematics dialog where you can enter a value of 1000 in the Start Index section (see Figure 1) to annotate all of your components to a large value that is not potentially used in any design: It may work out best for you to use a very large number for your designations such as 1000. When linking schematics and PCB snippets you will want to give the components unique designators that will not potentially be used in your current design (or future designs).
