It is possible to load in the physical characteristics of another project including its Technology Layers, dielectric stackup information, metal types, dielectric brick materials and top and bottom cover metal. When you select Circuit - Technology File - Load from the project editor menu, a Browse window appears which allows you to select a Sonnet Technology File (.stf), Sonnet project, or substrate file (.matl). You may also execute this command by selecting "Load Technology" from the main pop-up menu in the Stackup Manager.
When you load a technology, the following occurs:
- Your project's dielectric layer stackup is completely replaced with the new dielectric layer stackup. Be careful if the number of dielectrics in your project does not match the number of dielectrics in the loaded technology file because unexpected results may occur.
- Your project's top and bottom box cover properties are replaced.
- Metal and brick types from the technology will be imported to your project. If the project already contained a metal or brick type with the same name, its properties will be replaced with those from the technology. Any metal or brick type in your project without a corresponding name in the technology will be left unchanged.
- Technology Layers from the technology file will be imported into your project. If the project already contained a technology layer with the same name, its properties will be replaced with those from the technology file. Any technology layer in your project without a corresponding name in the technology file will be left unchanged.
