no help |  | Move to Layer / Copy to Layer by anonymous - 24 Apr 2009, 21:12 CEST These functions do not work for cells. They seem to work for forms but not for cells. Any suggestions? by Juergen Thies - 25 Apr 2009, 6:27 CEST A refered cell is never modified. Ether edit the refered cell or flat it before. Please log in to post! The LayoutEditor™ is a program to design and edit layouts for MEMS/IC fabrication and CMOS IC design .Designing these layouts require a high precision. In IC design a sufficient resolution and a possibility of a high scaling is required. The resolution of the LayoutEditor can be set in a wide range and is normally set to 1 nano meter. A higher resolution makes no sense due to atomar structures. With this resolution the LayoutEditor can draw elements up to 4 meters. In many IC design houses this is enough for IC/MEMS which extend usually less than 0.1 meters.
The productions of MEMS/IC is done in many layers. For each of these physical CAD layers a belonging layer had to exist in the drawing. Additional logical layers are required for describing/naming purpose. So a lot of layers are needed. By default the LayoutEditor is limited to 128 layers. But it can easily be adjusted, if more layers are required.
IC Designs often contain a plenty of repeating structures. Essential for micro fabrication of these designs is therefor a hierarchical design. This means, that the complete repeating structure only exists once in a single cell. These cell is then referred multiple times in the main drawing. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | |
