altsyncram Megafunction

Parameterized true dual-port synchronous RAM megafunction. The altsyncram megafunction is available for all Intel device families supported by the Quartus® Prime software.

Intel recommends instantiating this function with the IP Catalog.

Note:
  • You can use the altsyncram megafunction to read data from and write data to in-system memory in devices with the In-System Memory Content Editor. To use the altsyncram megafunction with the In-System Memory Content Editor, you must turn on the Allow In-System Memory Content Editor to capture and update content independently of the system clock option (that is, the ENABLE_RUNTIME_MOD and INSTANCE_NAME parameters must be enabled) when instantiating the altsyncram megafunction with the IP Catalog.
  • You can use the Assignment Editor to add, change, or delete assignments and assignment values for megafunctions.
  • When you create your megafunction, you can use the IP Catalog to generate a netlist for third-party synthesis tools.
