Importing Files into the Layout Editor
Using the File > Import command, you can read the following files directly into the Layout editor.
- EDB, Cadence APC/Allegro/SiP, ANF, AutoCAD, GDSII, IPC2581a, XFL, Gerber, IDF, and ODB++ imports opens directly into a new project.
- ANX import opens directly into a selected project. Users select whether to add the import to a new design or to an existing design.
Split plane layers have not been poured (generated). Unused interior pads are not output. Nets have not been defined or have been "anonymized" away. Components lack reference designators or part numbers.
ODB++ allows the export of a .copper_weight for signal layers but not an actual thickness. Use a conversion factor of 1.4mil per ounce of copper. ODB++ v.8 allows for the export of .dielectric_constant, .loss_tangent and .bulk_resistivity but no material names. Generate the name of the layers by prepending ODB_COND_ and ODB_DIEL_ before the first layer the material properties show up in.
For the following, designs are imported with only the top and bottom layer visible:ODB++, Cadence APD/Allegro/SiP, and ANFV2.
