WEBENCH® Tools/TPS55340: xxxxxxxxxxx

Part Number: TPS55340

Tool/software: WEBENCH® Design Tools

Not sure this is getting posted. I did a boost converter design in Web bench. I attempted to export the design along with Eagle symbols/packages/device library's. IT looks like its suppose to work. I was nable to open the files in the Eagle side.  Anyone had any luck with this. I got this Error when I tried to open the .sch file

Error:

line 1, column 28864: invalid/missing attribute 'pad' in tag <connect>

If I try and use the library I get this error.

Loading O:/Engineering/Eagle/lbr/April20/2017-04-11_06-27-15.lbr ...

Error:

line 1, column 1: Start tag expected.

Any help would be great.

    Robert,

    Thanks for the question here. You had posted a similar question yesterday at e2e.ti.com/.../587969. Howard from our group did responded with request for more information. Can you provide that information to him to help him debug?

    Thanks,

    Surinder

    Hi Robert,

    Sounds like there is a bad component mapping in the design BOM. There is a chance a diode footprint maybe an issue here. Could you please use the select alternate component feature within the WEBENCH tool and select a different package for the diode and test the schematic import again?

    As Surinder stated that I did request for your design information from yesterday's post. Please share the design here if you would like me to debug the issue.

    Hi Howard,
    My design is here
    webench.ti.com/.../SD2.cgi I think.

    I am new to Webench. I see the share Design but it looks like an Email is needed. I attempted to respond to the Email notification I got but that appears to bounce because I don't have permission to Email back?? If you enter Web bench and use a 3-5-3.7vdcin, 15vdc@1amp out you only get one device that can do that. TSP55340RTER. If you run the only device you get the design I was attempting to export. I would be interested in how you know which device as the errors reported didn't appear to point at anything. Also the naming convention of the files exported is odd, is there any info on what that means> Eagle expects .sch, .pcb, lbr. I see these in the body of the name but the suffix is odd.

    Hi Robert,
    Thank you for sharing the design. I was able to isolate the problem to the SDRD10200TR diode. It looks to have incorrect pin mapping and EAGLE is sensitive this issue. I will make the correction and hope to release the fix in a day or two.

    How to tell which component? Eagle gives an error which line/column location of the error in the XML file. Open the .sch file in Notepad++ and convert the XML file in a more readable format like below, and I can identify which component caused the issue...

    <deviceset name="SBRD10200TR" prefix="">
    <gates>
    <gate name="1" addlevel="always" y="0" x="0" symbol="SBRD10200TR@1"/>
    </gates>
    <devices>
    <device name="SBRD10200TR" package="DPAK">
    <connects>
    <connect pad="1" pin="A@1" gate="1"/>
    <connect pad="2" pin="A@2" gate="1"/>
    <connect pad="3" pin="K@3" gate="1"/>
    </connects>
    <technologies>
    <technology name="">
    <attribute name="Datasheet_URL" value="www.smc-diodes.com/.../SBRD10200%20N1314%20REV.-.pdf" constant="no"/>
    <attribute name="Io" value="10.0" constant="no"/>
    <attribute name="VRRM" value="200.0" constant="no"/>
    <attribute name="VFatIo" value="0.95" constant="no"/>
    <attribute name="Manufacturer_Part_Number" value="SBRD10200TR" constant="no"/>
    <attribute name="Vendor" value="SMC Diode Solutions" constant="no"/>
    <attribute name="Manufacturer_Name" value="SMC Diode Solutions" constant="no"/>
    </technology>
    </technologies>
    </device>
    </devices>
    </deviceset>


    On the exported file naming scheme? Yes, i agree but it's a limitation with our tool. Also, there is a bigger issue where it's not allowing the user to export the design as a project which it would make life so much easier using the common library between the schematic and the PCB.
