11.2 Chip Planner Views

Scalar members of a bus port are grouped under the bus. All bus ports can be collapsed or expanded as shown in the following figure.

To see the properties of the port, select the port. The properties of the port you selected is displayed in the Properties Window. The selected port is also highlighted in the Floorplanner View and the World View.

In the Port View, you can:

• Place ports to locations—Select a port, and then drag and drop it into the Floorplanner View at a valid resource location to assign the element to that location. All valid port locations are highlighted when you drag the selected element into the Floorplanner View.
• Unplace ports from locations—Right click the port and choose Unplace From Location to unassign a port.
• Lock Port to location—Right click the port and choose Lock Placement to lock selected port to the assigned location. This option is enabled only when the port is already placed in a location.
• Unlock Port from location—Right click the port and choose Unlock Placement to unassign the port. This option is enabled only when the port is already locked to a location.
• Region Assign—Right click a port and choose Region Assign. The Select Region dialog opens, and shows the regions available to assign that element. This dialog opens even if there are no User regions to which the selected item can be assigned. See the following figure.

• Unassign Port from Region—Right click the port and choose Unassign Macro to Region to unassign a port macro from a region. This option is enabled only if the port is already assigned to a region.
• Unassign All—Right click the port and choose Unassign All to unassign all the ports that are assigned to regions.
• Unassign Selected Ports—Right click the port and choose Unassign Selected Ports to unassign all the selected ports that are assigned to regions.
• Check DRC rules of selected interface—For a selected interface, DRC rules can be verified by selecting this option. A message in the Log window informs you whether the DRC rule check is successful.

Click the sort icon to sort the Ports by ascending or descending order, type, and port state:

Either the traditional match filter or Regular Expression match filter is available. Enter a port name in the Filter text box to filter ports. Enable the Use RegEx check box to use Regular Expression match filtering.

Click the component/primitive to find out the properties of the logic element you have selected. The properties of the component/primitive are displayed in the Properties Window. The selected design element is also highlighted in the Floorplanner View and in the World View.

Select a design element to:

• Assign elements to locations—Right click a design element and choose Place to Location to assign the element to that location. All valid resource locations are highlighted in the Floorplanner View when you drag the selected element into the Floorplanner View. Only a single element can be assigned at a time.
• Unassign element from location—Right click a design element and choose Unplace from Location. You can select multiple design elements/components and unassign them.
• Lock element to location—Right click a design element and choose Lock Placement to lock the selected element to an assigned location. This option is enabled only when the element is already placed in a location. You can select multiple design elements/components and lock them.
• Unlock element from location—Right click a design element and choose Unlock Placement to unlock or unfix a design element that is already locked to a location. This option is enabled when the element is already locked to a location. You can select multiple design elements/components and unlock them.
• Region assign—Right click a design element and choose Region Assign. A new Select Region dialog box provides you different regions available to assign that element. This dialog box appears even if there are no User regions to which the selected item can be assigned. You can also drag and drop the selected elements directly into a region in the Floorplanner View. If the selected elements are not compatible or over-booked for the desired region, the selection is not assigned to the region and invalid elements are shown in red in the Properties window.
• Unassign element from region—Right click a design element and choose Unassign Macro from Region to unassign a design element/macro from a region. This option is enabled only if the element is already assigned to a region. You can select multiple design elements/components and unassign them from a region.
• Unassign all—Right click the port and choose Unassign All to unassign all the elements that are assigned to regions.
• Unassign selected ports—Right click the port and choose Unassign Selected Ports to unassign all the selected elements that are assigned to regions.

Enter a macro name in the Filter text box to filter the design elements. From the pull-down menu of the Sort icon, choose either the traditional match filtering, wildcard filtering, or Regular Expression match filtering.

Click the Sort icon:

to sort in ascending or descending order, the type (Filter by Macro Type), and state (Filter by State) of the logic element.

Enter a macro name in the Filter text box to filter the design elements. From the pull-down menu of the Sort icon, choose either traditional match filtering, wildcard filtering, or Regular Expression match filtering.

Click to select the net. The net properties are displayed in the Properties Window. The selected net is also highlighted in the Floorplanner View and the World View.

From the Net view, you can:

• Change Net Color—Right click a net and choose Net Color to change the net color. This opens a color palette from which you can assign the desired color to the selected net.
• Region Assign—Right click a design element and choose Region Assign. The Select Region dialog opens, and shows the regions available to assign that element. This dialog box opens even if there are no User regions to which the selected item can be assigned. See the following example.

  

• Check the Assign with Driver check box to assign all the net macros including driver macros to a region. This option is enabled if there is a valid Region created over the required resources. You can select multiple nets and assign them to a region.
• Unassign All—Right click the port and choose Unassign All to unassign all the nets that are assigned to regions.
• Unassign Selected Nets—Right click the port and choose Unassign Selected Nets to unassign all the selected nets that are assigned to regions.

Sort the nets in ascending or descending order.

Enter a net name in the Filter text box to filter net names. From the pull-down menu of the Sort icon, choose either traditional match filtering, wildcard filtering, or Regular Expression match filtering. You can also filter with criteria specific to nets, such as fanout values, net types, and routing status (routed or unrouted).

A global net is a net that uses global routing resources for routing a signal from source to destination logic clusters. These include Chip Globals Resources/Global Buffers (GB), Row global resources/row global buffers (RGB), and Half-Chip Globals (HGB for RTG4). Clocks, Async Reset, and nets with high fanout are typically routed through these global routing resources.

Global signals (G[n:0]) reach the logic clusters through row global signals (RG[7:0]) generated by an associated row global buffer (RGB). RGB are inferred by the layout tool. Depending on the placement of the design elements, it distributes the fanout of the global nets across multiple RGBs. The Net View shows this break-up for such global nets.

The following figure shows an example of Global Nets with different fanouts.

The following figure shows the Floorplanner View of the Global Net.

The following figure shows the Properties window of Global Nets, which appears at the right side of the Floorplanner View.

Three types of regions are available for creation:

• Inclusive Region
• Exclusive Region
• Empty Region

Click the region in the Region View. The properties of the region you selected are displayed in the Properties Window. The selected region is also highlighted in the Floorplanner View and the World View.

Enter a region name in the Filter text box. From the pull-down menu of the Sort icon, choose traditional match filtering, wildcard filtering, or Regular Expression match filtering.

In addition to ascending or descending order display, a filter is available for the Region View to display user regions based on region types:

• Inclusive—Shows all inclusive regions.
• Exclusive—Shows all exclusive regions.
• Empty—Shows all empty regions.
