Description
Byte address for
reserved block area
—
Specifies the start address of the reserved block
area for bad block management.
NAND flash memory may contain bad blocks that
contain one or more invalid bits. The reserve
blocks replace any bad blocks that the PFL IP core
encounters. Altera recommends that you reserve a
minimum of 2% of the total block. (Available only
if you select NAND Flash.)
On-die ECC
support
On or Off
Enables the support for on-die ECC. Certain
NAND flash memory devices has on-die ECC.
Allows the PFL IP core to use the on-die ECC of
the flash memory device.
Turning off this option allows the PFL IP core to
generate its own ECC engine. (Available only if
you select NAND Flash.)
Flash Programming
Flash programming
IP optimization
Area, Speed
Specifies the flash programming IP optimization.
If you optimize the PFL IP core for speed, the flash
programming time is shorter but the IP core uses
more LEs. If you optimize the PFL IP core for area,
the IP core uses less LEs, but the flash program‐
ming time is longer. (Available only if you select
CFI Parallel Flash.)
FIFO size
—
Specifies the FIFO size if you select Speed for flash
programming IP optimization. The PFL IP core
uses additional LEs to implement FIFO as
temporary storage for programming data during
flash programming. With a larger FIFO size,
programming time is shorter. (Available only if
you select CFI Parallel Flash.)
Add Block-CRC
verification acceler‐
ation support
On or Off
Adds a block to accelerate verification. (Available
only if you select CFI Parallel Flash.)
FPGA Configuration
External clock
frequency
—
Specifies the user-supplied clock frequency for the
IP core to configure the FPGA. The clock
frequency must not exceed two times the
maximum clock (
DCLK
) frequency acceptable by
the FPGA for configuration. The PFL IP core can
divide the frequency of the input clock maximum
by two.
