altdq Altera® IP

Data strobe Altera® IP. The altdq Altera® IP transmits and receives data on both edges of the reference clock. The altdq Altera® IP is available for Cyclone® IV.

Altera recommends instantiating this function with the IP Catalog.

Note:
  • For this Altera® IP, the IP Catalog generates output files with multiple entities or modules. The top-level entity or module is located at the bottom of the file.
  • If your design does not connect to a DQS bus, you should use the altddio_in, altddio_out, oraltddio_bidir Altera® IP rather than the altdq Altera® IP.
  • To interface with the p and n-pins, you can instantiate your altdq Altera® IP then instantiate an I/O buffer Altera® IP.
  • When you create your Altera® IP, you can use the IP Catalog to generate a netlist for third-party synthesis tools.
Note: More information is available on the altdq Altera® IP on the Altera website.
