The Edit Parameters Button: Edit Conversion Parameters
This command brings up a text editing window displaying the LongName, Description, StreamIn, StreamOut, and
NoDrcDatatype lines for the current layer, as they would appear
in the technology file. Changing the current layer will update the
listing to the parameters for the new current layer. The user can add
new lines or modify existing lines as desired. The Save Tech
button in the Attributes Menu can be used to write a new
technology file containing the modifications.
To add a specification, select the desired keyword in the Keywords menu of the editor. The user will then be asked to enter
the associated text on the prompt line.
Clicking on a line in the listing will select the line. The text for
the selected line can be edited, or the line deleted, with the Edit and Delete buttons in the editor's Edit menu. The
Edit menu also contains an Undo button, allowing the last
operation to be undone.
The syntax for the keywords is described below. The LongName
and Description fields of layers are multi-purpose and do not
exclusively pertain to conversion functions. Their inclusion in this
editor is due to lack of a better place for this functionality. The
remaining parameters are specific to conversion, and in fact GDSII and
OASIS conversion only.
-
- LongName longname
This will set (or reset) the long name field of the current layer. If
no non-space characters are found after the keyword, the statement is
ignored. Leading and training white space is removed from the
argument.
- Description description_string
This will set the description field of the current layer. If no
non-space characters are found after the keyword, the statement is
ignored. Leading and training white space is removed from the
description string.
- StreamIn layer_list [, datatype_list]
This keyword specifies a set of layer/datatype combinations that will
map to the present Xic layer when reading GDSII and OASIS files.
Any number of such lines can be present. The layer_list is a
space-separated list of tokens, each of which is either a GDSII layer
number (``32'') or a range of numbers (``35-41''). The datatype_list is similarly constructed, and is optional. The
numbers in either list can range from 0 to 255. If a datatype_list appears, it is separated from the layer_list
with a comma. The line specifies that each of the datatypes listed on
each of the GDSII layers listed will be converted to the present
Xic layer. If the datatype list is absent, it defaults to
``0-255''. For example,
StreamIn 5 7 8 21-30, 0 20-63
specifies that datatypes 0 and 20-63 on GDSII layers 5, 7, 8, and
21-30 will be mapped to the present Xic layer as a GDSII or OASIS
file is read. Note that GDSII layers cam be mapped to more than one
Xic layer. In this case, the geometry will be created on each of
the Xic layers mapped to.
- StreamOut out_layer [out_datatype]
This line specifies a layer/datatype combination to be used when
generating GDSII and OASIS files for the present Xic layer. One of
these should appear for each Xic layer. The out_layer and
out_datatype can be in the range 0 - 255. Note that often the
end of range values are reserved in other CAD environments, and that
some releases of the GDSII format support only 64 layers and
datatypes. The default datatype, if not given, is 0. If there are
more than one StreamOut lines given for a layer, the objects
will be added to the GDSII or OASIS file on each of the GDSII layers
specified. There is no default.
- NoDrcDatatype datatype
If this keyword is given, then any object that has the given datatype
will be ignored during DRC. On output, objects that have their DRC
skip flags set will be written with this datatype, and not the default
datatype given in the StreamOut line. The given datatype should
appear in the input mapping for the layer.
