2.7.10. Implementing Clock Enable for On-Chip Memories

Follow these guidelines to implement clock enable for on-chip memories:
  1. To avoid spurious writes during PR programming for memories, implement the clock enable circuit in the same PR region as the M20K or MLAB RAM. This circuit depends on an active-high clear signal from the static region.
  2. Before you begin the PR programming, assert this signal to disable the memory’s clock enable. Your system PR controller must deassert the clear signal on PR programming completion. You can use the freeze signal for this purpose.
  3. Use the Intel® Quartus® Prime IP Catalog or Platform Designer to instantiate the On-Chip Memory and RAM Intel® FPGA IP cores that include an option to automatically add this circuitry.
    Note: If you turn on the Implement clock-enable circuitry for use in a partial reconfiguration region option when parameterizing RAM Intel FPGA IP from the IP catalog, the Intel® Quartus® Prime software adds a freeze port to the RAM IP for use in the PR region.
