The Edit Tech Params Button: Set Parameters

Pressing the Edit Tech Params button in the Extract Menu brings up the Extraction Parameter Editor. This includes a text window which contains a list of the the keywords (as described in 13.1.2) and parameters for the extraction subsystem for the current layer. The text can be modified or added to, which will change the keyword definitions for the current layer. Selecting a new current layer will change the text to that appropriate for the new layer. A message will indicate if errors were encountered. Changes made will be reflected in subsequently generated technology files produced with the Save Tech command button in the Attributes Menu. These keywords apply to layers in physical mode only.

Listed keyword lines can be selected by clicking on them with the mouse. A selected line can be deleted with the Delete button in the Edit menu, or may be edited with the Edit button in the same menu. In Edit, the user is prompted for the appropriate values in accord with syntax expected for that keyword line. A modified or deleted line can be recovered with the Undo button.

A new keyword line can be added by selecting one of the entries in the Keywords menu. The user is prompted for any values associated with the keyword. The addition (or replacement) can be undone with the Undo button.

When adding a keyword, redundant and inconsistent keywords that are already in the list, such as a previous instance of the keyword, are removed. In other cases, a pop-up message will appear if inconsistent keywords are found. These are usually harmless, as inappropriate data will be ignored.

The Attributes menu allows extraction-related parameters that do not correspond to layers to be set.

Pressing the Device Block button produces a drop-down list of device blocks from the technology file, plus three additional buttons: New, Delete, and Undelete. The device blocks are listed in order of their definition, as the block name followed by the prefix, if any. Pressing New or any of the device block name entries brings up a text editor loaded with the indicated block, or empty for New. The text for the device block can be entered into the editor. Adding a block with the same name and prefix (or lack of a prefix) as an existing block will overwrite the existing block. Saving with the Save button in the editor will update an existing block or add a new block to the internal device list. The Save button in the editor does not save to disk. The Save Tech command can be used to generate a new technology file which will contain the new block, or the Save As button in the editor can be used to save the block as a file.

To delete a device block, press the Delete button in the Device Block menu, then select a device block from the same menu. That block will be removed from the menu. The name will disappear from the menu, and it is removed from consideration in extraction. The block can be restored with the Undelete menu entry, but only one deletion is remembered.

The syntax generated for keyword entries is exactly that used in the technology file. Each line contains a keyword plus any arguments. The keywords are described in 13.1.2.
