Table 11–7. WYSIWYG Atoms
To enable the cycloneiii_crcblock primitive in version 8.0 SP1 or earlier of the
Quartus II software, turn on the error detection CRC feature in the Device and Pins
Options dialog box. This is not required when you are using version 8.1 and later of
the Quartus II software.

input and output ports of the atoms for Cyclone III device family are similar, except
for the cyclecomplete port which is for Cyclone III LS devices only.

lists the input and output ports that must be included in the atom. The
Device
shows an example of how to define the input and output ports of a
Unique identifier for the CRC block, and represents any identifier name that is
legal for the given description language (For example Verilog HDL, VHDL,
AHDL). This field is required.
This signal designates the clock input of this cell. All operations of this cell are
with respect to the rising edge of the clock. Whether it is the loading of the
data into the cell or data out of the cell, it always occurs on the rising edge.
This port is required.
This signal is an input into the error detection block. If shiftnld=1, the
data is shifted from the internal shift register to the regout at each rising
edge of clk. If shiftnld=0, the shift register parallel loads either the
pre-calculated CRC value or the update register contents depending on the
ldsrc port input. This port is required.
