altufm_osc Megafunction

Oscillator megafunction. The altufm_osc megafunction provides access to the internal User Flash memory (UFM) oscillator in MAXII devices. The oscillator can be used as a general clock source without using the flash memory. You cannot use the altufm_none,altufm_parallel,altufm_spi, and/or altufm_i2c megafunctions if you instantiate the altufm_osc megafunction in a device.

Intel recommends instantiating this function with the IP Catalog.

Note:
  • For this megafunction, 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.
  • 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 altufm_osc megafunction on the Altera website.
