ML2ZL is a tool that converts the symbols and geometries for the Mentor Board Station into symbols and footprints for the Zuken CR5000. If Mentor and Zuken are used together, it is possible to reduce loss caused by double library works by converting Mentor Library into Zuken Library by use of ML2ZL. Each company has different specifications for geometry, so based on each company’s standards for geometry creation, some modifications are necessary and are supported.
