Description
Required
Type
Parameter Name
Specifies whether the write-protect port protects
only the upper half of the UFM block or the entire
UFM block from writes/erases. Values are FULL
and UPPER_HALF. If omitted, the default is
FULL.
No
String
MEM_PROTECT
Specifies the memory size. Values are 1K, 2K, and
4K. If omitted, the default is 4K.
Yes
String
MEMORY_SIZE
Specifies the oscillator frequency for the user flash
memory. Values are 180000 ps (5.56 MHz) or
300000 ps (3.33 MHz). If omitted, the default is
180000 ps. The OSC_FREQUENCY setting
controls the oscillator frequency during
simulations and does not affect the device’s
oscillator frequency, which can range from
3.33 MHz (300000 ps) to 5.56 MHz (180000 ps).
(2)
No
Integer
OSC_FREQUENCY
Specifies the write mode. If omitted, the default
is SINGLE_BYTE.
No
String
WRITE_MODE
Allows you to assign Altera-specific parameters
in VHDL Design Files (.vhd). The default is
UNUSED.
No
String
LPM_HINT
Identifies the library of parameterized modules
(LPM) entity name in VHDL Design Files.
No
String
LPM_TYPE
Notes to Table 2–7:
1. This parameter is used for modeling and behavioral simulation purposes
2. This parameter is used for simulation purposes only.
