9.6.3 Memory Interface View Columns
(Ask a Question)The Memory Interface view detects the type of Memory Interface in the
design and presents the ports in the Ports View. The Memory Interface view displays the
following I/O information in the view. Each of the column can be sorted
(ascending/descending order) or filtered:
- Port Function—Formal port name of the Memory Interface. The ports specific to the memory interface type are loaded into the Port View.
- Port Name—Port name of the Memory Interface instance in the design.
- Pin Number—Package pin number assigned to the port of the Memory Interface.
- Function—More descriptive function name of the Port, which identifies the type of I/O (for example, HSIO for High-speed I/Os or GPIO (General-purpose Input/Output).
- Max Memory Width—Maximum memory width of the DDR. This is a fixed read-only value specific to the Edge_Anchor and is different with different Edge_Anchors.
- Max Data Rate—Maximum data rate in Mbps. This is a fixed read-only value specific to the Edge_Anchor and is different with different Edge_Anchors.
Note: When making DDR placement, see the memory width and data
rate of the DDR Memory used in the design (as displayed in the Ports View). Make sure that
the Edge_Anchor location, where you want to place the DDR memory, can accommodate the DDR
memory in terms of the memory width and the data rate. This will avoid invalid
placement.
- Bank Name—the I/O bank name of the port
- High-speed I/O Clocks—specifies the number of High Speed I/O clocks
The Pin Number and Function are the same as what are listed in the PPAT for the selected device and package. The PPAT for each PolarFire package are provided in the PolarFire_<package> Pinouts file on the PolarFire Documentation web page.
