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?
My first thought was Artwork Conversion Software - but I don't believe they have anything that goes from PDF to Stream format (aka GDSII). That said, I did find a few companies that provide a PDF to DXF (an AutoCad format) converters - just do a google search for "Convert PDF to DXF". And Artwork provide a tool to convert DXF to GDSII (I think you can also do it with the Allegro PCB/Packaging tools too).
How successful this flow is remains to be seen. You are probably better off requesting the lead frame in a drawing format directly from the package provider, rather than trying to reverse engineer it from a PDF. Almost certainly they will have it in a form used in a CAD tool - either something like AutoCad, or even Allegro Package Designer.
