LASI (Layout System for Individuals) was a free to use Windows tool to view and edit design files. It has been discontinued and its home page no longer exists. It has used a own file format. There exists two variants of the format. File with the ending .tlc can store only a single cell. tld file can contain a whole design. The data can stored in physical values and in relative values. If the data is stored in relative values it is converted to physical units via the lamba value. The LayoutEditor can import both of these formats. An export is not supported and also does no longer make sense as the LASI software is no longer available.
