In Classic Projects, the Common Libraries folder is a special virtual container for reusable HDL libraries, such as standard VHDL (STD, IEEE), vendor, or third-party IP libraries.
Key Characteristics
- Virtual Folder: It does not exist on your physical disk; it only contains references to folders on your filesystem.
- Superficial Analysis: To save compute and memory, Sigasi performs only essential analysis on files in this folder. Most linting checks are skipped, as these files are assumed to be “read-only” and error-free.
- Efficient Workflow: It is recommended to add external dependencies here using the Linked Resource mechanism. This avoids copying large library trees into your project while significantly reducing the performance overhead of analyzing them.
