    transfer of electrical components

    Emir Heco

      Hello All,


      We are about to migrate all of our data from our current system into the EPDM.  It appears that it will be a smooth transition for most SolidWorks files. For our electrical board layout tool, we use a software called Eagle. In this software we have a list of all electrical components, sort of like a tool box. We populate our boards from this tool box and each electrical component gets assigned a reference designator (R1, C2 and so on). We have a feature that generates an automatic BOM for the board. In this BOM we have fields for reference designator, vendors and other vendor information. What it comes down to is that one resistor can have a thousand diff reference designators and in fact same designators depending on which board the resistor is used on. Is there any way to capture this information in EPDM. A more general question is how do people deal with their electrical component files in EPDM.


      Thanks in advance for your help.

          We have a customer that is using Eagle as well and would like to do the same.  We have proposed writing a migration tool for them to bring in the components as virtual documents and then using the BOMs to generate virtual documents that represent the boards.  The migration tool would generate the relationships between the boards and the components according to the BOMs.  Also some of the boards have SW models that represent them so in these cases we will not be using a virtual document, but instead link the component virtual documents to the SW file.  However, they did not bring up the point about the reference designators.  I guess the question to you would be how exactly would you want the reference designator information seen or tracked.  My understanding is that the relationship between the designator and the actual component lives at the board level and not at the component level.  So perhaps using named BOMs of the boards where you could change the value of the designator might be the best way to go.  The import tool could generate the relationships of the components and the boards then produce a named BOM and fill in the reference designators based on the Eagle BOM.  That’s my first thought.  I’ll be interested in seeing what others think.
