Convert pdf file to gds

tyanata

Hello,

I want to put on the table one problem which we face somehow regularly. Each time when we receive the leadframes for the packages which our custmers want to use they are in PDF format, but we need them in GDS in order to create the bonding diagram  which is sent to the assembly house. So after that we are using multiple tools and stunts in order to do the convertion, but the approach is not professional at all.

My question is there way ( cadence tool or skill script ) to convert PDF to some cadence readable format, in order to be opend as a lyout view?

  • Hello Andrew,

    I did some thing different opened the PDF file in GIMP and then converted it to  XPM which was much smaller as size.

    Then this XPM was successfully imported in the layout using your script.

    But anyway the final layout picture looked pretty ugly ( wires to bondpads looked like rows of squares for example ).

    So I will try to find another decision, convert PDF to some vector ascii format and then to extract data.

    In fact we did some thing similar. Converted PDF to PS and then opened PS file in text editor, and just manually taken the sizes of the lines. And using this number pairs to create lines in layout, we succeeded to do that in one old Layout tool called ( ICED ) but now I will try to automate that for Cadence.

    Best regards,
