Description
A part number for a particular
memory device. Choosing an entry
other than Custom sets many of the
parameters in the w izard to the
correct value for the specified part. If
any such parameter is changed to a
value that is not supported by the
specified device, the preset
automatically changes to custom.
You can add your o w n devices to
this list by editing the
memory_types.dat file in the
\constraints directory.
Selects QDRII or QDRII+ SRAM
devices.
The memory controller clock
frequency. The constraints script
and the datapath use this clock
speed. It must be set to the value
that you intend to use. The first time
you use IP Toolbench or if you turn
on Automatically generate the
PLL , it uses this value for the IP
Toolbench-generated PLL’s input
and output clocks .

Note to Table 3–8 :
(1)
IP Toolbench allows you to enter up to 600 MHz, but Altera only supports the
QDRII SRAM controller up to 300 MHz.
