lpm_rom Intel® FPGA IP
Parameterized ROM Intel® FPGA IP.
Important: When possible,
               Intel use the altsyncram Intel® FPGA IP instead
            of the lpm_rom Intel® FPGA IP. This Intel® FPGA IP is provided
            only for backward compatibility. This option is available for all Intel devices except MAX3000 and MAX7000 devices.
You can
            use the lpm_rom Intel® FPGA IP to read data from and write data to in-system
            memory in devices with the In-System Memory Content Editor in two
               ways:
- In the Parameter Editor, turn on Allow In-System Memory Content Editor to capture and update content independently of the system clock.
- In the HDL file, when instantiating the IP core, enable the ENABLE_RUNTIME_MOD and INSTANCE_NAME options
You can use the Assignment Editor to add, change, or delete assignments and assignment values for Intel® FPGA IP.
When you create the Intel® FPGA IP, you can use the IP Catalog to generate a netlist for third-party synthesis tools.
