Genaeral description: The sample project "calc3ka" is incorrectly specified as a HDL flow project. The project subdirectory does not \ contain any HDL files, only schematic sheets.
When the project pdf file is opened in F1.5, the default flow is HDL, but no source/macro files are found by the project manager. When the flow is changed to a schematic flow, all works as intended.
解决方案
Open the sample project. Then manually change the design flow from an HDL to a schematic flow as follows: select File -> Project Type, then choose Schematic, and Change.
