Parameterized ROM megafunction.
Important: Important: Altera 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 Altera 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 the lpm_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, the ENABLE_RUNTIME_MOD and
INSTANCE_NAME parameters must be enabled) when
instantiating the lpm_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.
Note: More information is available on the lpm_rom megafunction on the Altera website.
