![]() ![]() The GDSII file format is limited to array of 32000x32000. If a rotation, scaling or mirroring is required, perform it within the repeating cell, don't rotate, scale or mirror huge arrays and use a orthogonal spacing, So a optimal performance can be achieved.However there are some things to consider: Some examples designs are part of the documentation and can be downloaded as cad file: CircleArrayExample and LargeArrays The second example file has more than 81,500,000,000,000 polygons. The LayoutEditor is designed to handle such huge arrays. The size of array can extent 100,000x100,000 repetitions. Nanotechnology designs contain extremely small structures which are repeated very often. Resolution input dialogs may be limited to 1E-12 meter as a higher resolution make no physical sense and the maximal design dimension will scale with the resolution. ![]() Adjustment is possible via the SetupDialog, the context menu of the position status or via a macro command. 9.99E99 meter) enough to draw a nuclear and enough to design the universe. In the LayoutEditor it is possible to change it to any value you like. A database unit of 1 nm is a quasi standard in MEMS/IC and many other programs are limited to this resolution. In the GDSII file it is also named database units. The resolution is the minimum size or step a CAD system can handle. The LayoutEditor to satisfy all of these requirements: However the requirements differ: non manhattan structures are typical (as in MEMS design), a higher resolution is required, huge repeating structures exists. Designing nanotechnology is done with the same tools as used for integrated circuits.
