lpm_rom Megafunction
Parameterized ROM megafunction.
Important: Important: Intel recommends using the
altsyncram megafunction instead of the
lpm_rom megafunction. This megafunction is provided only for
backward compatibility. This option is
available for all Intel devices except MAX3000 and
MAX7000 devices.
Note:
- You can use the
lpm_rom
megafunction to read data from and write data to in-system memory in devices with the In-System Memory Content Editor.
To use thelpm_rom
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, theENABLE_RUNTIME_MOD
andINSTANCE_NAME
parameters must be enabled) when instantiating thelpm_ram_dq
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.
