| |
| 1.
How much die size reduction is achieved by migrating
a design to a HardCopy device? |
|
The die size is reduced by as much as 70%.
|
| |
|
|
|
|
|
| 2.
How much die size reduction can be expected for an
ARM®-based Excalibur HardCopy device? |
| While the logic are of the Excalibur
design will be reduced by as much as 70%, the ARM
processor is a hard intellectual property (IP) core
already optimized for a 0.18-mm process, so it will
not shrink. |
| |
|
|
|
|
|
| |
| 3.
What kind of performance improvement will be achieved
by migrating to a HardCopy device? |
| Significant performance increases
can be achieved by migrating to HardCopy devices.
However, the improvement factor is design-dependent
and cannot be specified before Altera's evaluation
of the PLD design. |
| |
|
|
|
|
|
| |
| 4.
Can intellectual property (IP) cores be migrated to
HardCopy devices? |
| Yes, soft IP cores can be migrated
to HardCopy devices. |
| |
|
|
|
|
|
| |
5.
Do HardCopy devices support Joint Test Action Group
(JTAG), LVDS, and other features available in Altera
high-density devices?
|
| Yes, HardCopy devices can support
all the features of APEX 20KE devices except SignalTap®
logic analysis. |
|
|
|
|
|
| |
6.
Will HardCopy devices consume less power than PLDs?
If so, what will be the power consumption rate?
|
| Yes, HardCopy devices will typically
consume less power than PLDs, but this depends on
the design parameters. Power consumption will be design-dependent. |
|
|
|
|
|
| |
7.
Will HardCopy devices be available in the industrial
temperature range?
|
| Yes. Industrial temperature HardCopy
devices will be available. |
|
|
|
|
|
| |
8.
Will I/O performance be the same in HardCopy devices
as in the original PLD?
|
| Yes. The I/O buffer design is identical
to that of the original PLD. |
|
|
|
|
|
| |
9.
Are the same PLLs supported in HardCopy devices?
|
| Yes. All the four phase-locked loops
(PLLs) available in the PLD remain in the HardCopy
device. They have been optimized for the smaller die
size and clock distribution tree. |
|
|
|
|
|
| |
10.
Are ROM and RAM supported in HardCopy devices?
|
| Yes. HardCopy devices support ROM
and RAM. However, pre-load RAM will not be supported. |
|
|
|
|
|
| |
11.
If pre-load RAM is not supported, how can ROM be
implemented?
|
| ROM can still be implemented. As long
as there is no need to be able to write to the memory,
extracting the bit pattern from the .pof file will
configure the ROM, and the embedded system blocks
(ESBs) will be hard-wired to implement the required
configuration. |
|
|
|
|
|
| |
12.
Are content-addressable memory (CAM) and product-term
logic supported in HardCopy devices?
|
| Yes. HardCopy devices support CAM
and product-term logic. However, pre-load CAM is not
supported. Most CAMs are initialized with a certain
pattern, so this initialization will need to be carried
out by an external controller. |
