Refer to the following table for a description of the General page options.
| Option | Description |
|---|---|
| Edit Mode | Specifies what modifications can be made to your design. You can select Read Only, No Logic Changes, or Read Write. |
| Program Options | |
| Speed Grade | Determines the speed (toggle rate) of the part you are editing. You can select an appropriate speed from the list box. |
| Automatic Deselect | When enabled, selected objects are deselected after a Delay, DRC, EditBlock, Hilite, Setattr, Getattr, or Post Attr command is performed. When disabled, selected objects remain selected after one of these commands is performed. The default is enabled. |
| Automatic Hilite | When enabled, delay paths are automatically highlighted after a Delay command, and the net being edited is highlighted after manual routing. By default, the option is disabled. |
| Automatic Post | When enabled, a component, net, path, macro, or external pin properties dialog box is automatically displayed after an Add command, or after a route or autoroute operation in which a new net is created. By default, this option is enabled. |
| Stub Trimming | When enabled, only the portion of a routing resource that lies directly on the path between two routed pins is displayed in the Array window (for example, a portion of a long line or a pinwire). When disabled, the entire routing resource taken up by the route, such as an entire long line, is displayed in the Array window. The default is enabled. |
| Route Options | |
| Automatic Routing | When enabled, the system automatically routes any unrouted nets created as a result of an editing action, such as placing components, creating new nets, swapping components. The default is enabled. |
| Enhanced Manual Routing | When enabled, the Route command attempts to make a connection between user-specified resources. If the connection fails, it autoroutes between those resources. When disabled, no call to the autorouter occurs. By default, the option is enabled. |
| Delay Based Routing | When enabled, the autorouter takes delay values into account. When disabled, cost-based autorouting is done. Delay-based autorouting takes longer, but can result in better results, especially in a dense design. By default, the option is enabled. This option has no effect on the Autoroute All operation. |
| Pattern Matching | |
| Wild Cards (* and ?) | In the Find dialog, and with commands that accept patterns (such as Select and Unselect), you can use the wildcard characters, * and ?, The asterisk (*) represents any string of zero or more characters. The question mark (?) indicates a single character. |
| Regular Expressions | Pattern is a grep-like regular expression. |
Refer to the following table for a description of the Global Physical Constraints page options.
| Option | Description |
|---|---|
| Route Locking | Applies a lock routing constraint to all partially or fully routed nets in your design. The lock routing constraint specifies that the current routing cannot be changed or unrouted. |
| Delays | Applies a Penalize Tilde constraint to your design. This constraint penalizes those delays that are reported as only approximate, signified with a tilde (~) in delay reports by the percentage specified in this field. |
| Max Delay for All Paths | Applies a Maxdelay Allpaths constraint to your design. This constraint specifies the maximum delay for all paths in the design. |
| Max Delay for All Nets | Applies a Maxdelay Allnets constraint to your design. This constraint specifies the maximum delay for all nets in the design. |
| All Clock Nets | |
| Period (ns) | Applies a period constraint to your design, which specifies the clock period for all clock nets in the design. Either a Period or a Frequency should be entered in this dialog box, but not both. |
| First Pulse | Specifies whether the first pulse of the duty cycle is High or Low. |
| Duration (ns) | Specifies the duration of the first pulse of the duty cycle. |
| Tsid | Assigns a timing period or frequency to a timing specification. |
| Phase (ns) | Phase and factor are used to generate a derived clock based on the period of an existing timing constraint. This constraint is the master and the derived constraint is the slave. Phase is the delay of the initial edge of the master to the slave. |
| Factor | Phase and factor are used to generate a derived clock based on the period of an existing timing constraint. This constraint is the master and the derived constraint is the slave. Factor is a multiplier period of the master used to create a relative one for the slave. For example, if the period for the slave is one half that of the master, use a value of 0.5. |
| Max Skew | Applies a Maxskew constraint to your design, which specifies the maximum allowable clock skew for all clock nets in the design. |
