The technology editor works by converting a technology into a library of cells. You then edit the cells, using familiar Electric commands, and make changes to the technology. Finally, the technology editor translates the library back into a new technology.
Libraries which describe a technology are called technology libraries.
They use elements from the Artwork technology to describe their information.
Special commands from the Edit / Technology Editing menu aid in the manipulation of these libraries.
There are four types of cells in a technology library which describe the layers,
arcs, nodes, and support.
They are separated into these groups in the cell explorer.
The layer cells all begin with the name "layer-" and each one defines a layer in the technology.
For example, the cell called "layer-Metal" defines the metal layer.
The node and arc cells correspond to the primitives in the technology.
Their names always begin with "node-" and "arc-".
The support cell is always called "factors".
Any other cell in the library is ignored.
