[[File:Wikipediaoasisimage 2.png|thumb|This view is called a cell view. A cell can be a collection of placed geometric shapes. It also can be a collection of cells; each containing other cells and/or geometric shapes. Each cell must have at least one layer. In this view, each color represents a different layer within the cell. An integrated circuit can contain tens of thousands of unique cells and repeated instances of the same cell.]]

Below is a human-readable text representation of the OASIS binary file that allowed the expression of the above "top" cell view called "Placed__shapes_and_cells_within_an_IC_cell". The top cell is defined by a file-level standard PROPERTY record named S_TOP_CELL. The PROPERTY record below references a PROPNAME record (refNum=0) that has a ''propname-string'' called S_TOP_CELL. The top cell contains the placement of three cells called "bottom cells". Bottom cells contain geometric shapes only.
