As shown in fig. 5, the method includes:
step 101, loading a substrate file.
The embodiment of the invention supports the loading of the substrate file of the established process by a user, wherein the substrate file is generated by the user and comprises information such as layer name, layer type, layer material, layer thickness, layer position and the like.
