Using the Electric VLSI Design System

Chapter XI: MENU SUMMARY

| ## 6: The View Menu |

Each facet has a view associated with it. Although Electric defines a standard set of view types (layout, schematic, icon, skeleton, simulation-output, VHDL, document, and many netlist formats) it is possible to define new view types (for example, "fast layout") and to assign these views to facets. Special commands switch between the different views of a cell. This menu also controls the display of schematic frames. Finally, there are commands that automatically generate new facets of a different view type.

### New View Type... [3-11]

This command creates a new type of view for facets. You will be prompted for the name of the view and an abbreviation to use in facet names. The abbreviation appears in curly brackets after the cell name, for example MyAdder{fast}. |

### Delete View Type... [3-11]

This command deletes a view type. There cannot be any existing facets with this view. Also, it is not possible to delete the basic view types that are defined by Electric.

### Change Facet's View... [3-11]

This command changes the view type of the current facet. You will be prompted for the new view. Note that this is one of the few commands in Electric that is NOT undoable.

### Frame Options... [7-6]

This command allows you to control the drawing of a frame in the current facet. You can choose among 5 frame sizes ("A", "B", "C", "D", or "E") and also whether they are wider (landscape) or taller (portrait). In addition, you can provide information that will be displayed in the corner of the frame (currently, the only the company name and the designer's name). |

### Icon Options... [3-12]

This dialog controls how icons are created from schematics. For each type of port in the schematic, you can control on which of the four sides of the icon the port will appear. You can also control the location of ports and the style of their text. Yyou can control whether the icon has a body or leads for each port. Finally, you can control whether or not the icon has a Facet-Center in it. |

### Edit Layout View [3-11]

This command takes the facet in the current editing window and edits its associated layout view. If one does not exist, it is created.

### Edit Schematic View [3-11]

This command takes the facet in the current editing window and edits its associated schematic view. If one does not exist, it is created.

### Edit Multi-Page Schematic View... [3-11]

This command takes the facet in the current editing window and edits a particular page of its associated multi-page schematic view. You will be prompted for the page number. If that page does not exist, it is created. Multi-page schematics are described with the "pN" view type, where "N" is the page number. For example, to edit page 6 of cell "happy", look for the facet called "happy{p6}".

### Edit VHDL View [3-11]

This command takes the facet in the current editing window and edits its associated VHDL view. If one does not exist, it is created. Note that the VHDL view is a textual view, so you will now be using a text editor. See section 4-10 for more on text editing.

### Edit Icon View [3-11]

This command takes the facet in the current editing window and edits its associated icon view. If one does not exist, it is created.

### Edit Documentation View [3-7]

This command takes the facet in the current editing window and edits its associated documentation view. If one does not exist, it is created. Note that the documentation view is a textual view, so you will now be using a text editor. See section 4-10 for more on text editing.

### Edit Other View... [3-11]

This command takes the facet in the current editing window and edits an arbitrary associated view. You will be prompted for the view type. If that view of the facet does not exist, it is created.

### Make Schematic [3-12]

This command creates a new schematic facet of the cell in the current editing window. It is presumed that the current facet is a layout view. If there is already a schematic view of this facet, a new version of the schematic is created.

### Make Layout [3-12]

This command creates a new layout facet of the cell in the current editing window. It is presumed that the current facet is a layout or schematic view and that the new facet is layout in a different but similar technology. You will be prompted for the new technology.

### Make Skeleton [3-12]

This command creates a new skeleton facet of the cell in the current editing window. The new facet has the same size and ports, but none of the internal layout.

### Make Icon [3-12]

This command creates a new icon facet of the cell in the current editing window. The new facet has the same ports but a black-box look with input ports on the left, outputs on the right, power and ground on the top, and clock lines on the bottom.

### Make VHDL [3-12]

This command creates a new VHDL facet (a textual view) of the cell in the current editing window. All subfacets of the current facet are also translated to VHDL, and their descriptions are stored in views of the subfacet. If "VHDL stored in facet" is unchecked (in the VHDL Options... subcommand of the VHDL Compiler command of the Tools menu), all VHDL will be written to disk.
