Some general examples of Assignment Editor assignments to specific entity or nodes are: Assignments are logic functions you assign to a physical resource on the device, or compilation resources you assign to logic functions. The assignments appear in a spreadsheet in the main window of the Assignment Editor.
The other text colors are as follows: Using the Timing Wizard, you can specify an overall fMAX requirement for all clocks in the design or define settings that can be applied to individual clocks.
You can edit entity or node settings by specifying the entity or node name in the Edit bar of the Assignment Editor or search for an entity or node name using the Node Finder search tool on the View menu, click Utility Windows, then click Node Finder.
To create a new assignment or edit an existing assignment, you can either select quartus assignment editor cell you want to edit and choose Edit Cell Edit menuor single-click or double-click the cell you want to edit and begin typing.
If quartus assignment editor cell does not contain a value and cannot be edited, for example, the cells in the Source Name column in single-point assignments such as the Inverted Clock timing assignment, the cell appears with a gray background.
You can sort the contents of the columns alphabetically using the Sort Ascending and Sort Descending commands right button pop-up menu.
Assigning the node or entity to specific locations on the device e.
Figure 3 shows the Assignment Editor. If applicable, a drop down menu appears from which you choose the assignment or value you want to enter; otherwise, you type the appropriate information.
If the cell requires a hierarchy path to a specific node, for example, when an assignment requires you specify a source or destination path, you can click the arrow at the side of the cell and choose Node Finder from the menu.
An entity is any primitive or macrofunction that can be represented as either a name or a symbol in a design file. Settings defined for an individual clock can be applied to one or more other clocks in the design using the Assignment Editor.
The current cell appears with a blue background. The available spreadsheet columns vary for each type of assignment. You can resize, close, and move the Category Bar.
You can use the Undo and Redo commands Edit menu with the Assignment Editor, but these commands are not available for all actions, or they become disabled after performing certain tasks, such as sorting columns. The Category Bar contains all of the assignment types for the current device.
You can also change the order of the columns by dragging and dropping a column to a different location in the spreadsheet. If a certain cell cannot be edited and contains a value, for example, a value from the General Function column in the Pin category, the text appears dimmed and you cannot edit the value in the cell.
A node represents a wire carrying a signal that travels between different logical components of a design file. To delete assignments, use the Delete Rows command Edit menu. Figure 2 shows the Timing Wizard dialog box.
