High-Reliability, Low-Risk Solution
junction temperatures. Actel’s non-PLD architecture delivers
lower dynamic operating current. Our reliability tests show a
very low failure rate of 6.6 FITs at 90°C junction temperature
with no degradation in AC performance. Special stress testing
at wafer test eliminates infant mortalities prior to packaging.
Actel builds the most reliable field programmable gate arrays
(FPGAs) in the industry, with overall antifuse reliability
ratings of less than 10 Failures-In-Time (FITs),
corresponding to a useful life of more than 40 years. Actel
FPGAs have been production proven, with more than five
million devices shipped and more than one trillion antifuses
manufactured. Actel devices are fully tested prior to
shipment, with an outgoing defect level of less than 100 ppm.
(Further reliability data is available in the Actel Device
Reliability Report, at http://www.actel.com/hirel).
Minimized Security Risk
Reverse engineering of programmed Actel devices from
optical or electrical data is extremely difficult. Programmed
antifuses cannot be identified from a photograph or by using
an SEM. The antifuse map cannot be deciphered either
electrically or by microprobing. Each device has a silicon
signature that identifies its origins, down to the wafer lot and
fabrication facility.
Benefits
Minimized Cost Risk
Minimized Testing Risk
With Actel’s line of development tools, designers can produce
as many chips as they choose for just the cost of the device
itself. There will be no NRE charges to cut into the
development budget each time a new design is tried.
Unprogrammed Actel parts are extensively tested at the
factory. Routing tracks, logic modules, and programming,
debug and test circuits are 100 percent tested before
shipment. AC performance is ensured by special speed path
tests, and programming circuitry is verified on test antifuses.
During the programming process, an algorithm is run to
ensure that all antifuses are correctly programmed. In
addition, Actel’s Silicon Explorer diagnostic tool uses
ActionProbe circuitry, allowing 100 percent observability of
all internal nodes to check and debug the design.
Minimized Time Risk
After the design is entered, placement and routing is
automatic, and programming the device takes only about 5 to
15 minutes for an average design. Designers save time in the
design entry process by using tools with which they are
familiar.
Minimized Reliability Risk
Actel FPGA Description
The PLICE antifuse is a one-time programmable, nonvolatile
connection. Since Actel devices are permanently
programmed, no downloading from EPROM or SRAM storage
is required. Inadvertent erasure is impossible, and there is no
need to reload the program after power disruptions.
Fabrication using a low-power CMOS process means cooler
The Actel families of FPGAs offer a variety of packages,
speed/performance characteristics, and processing levels for
use in all high reliability and military applications. Devices
are implemented in a silicon gate, two-level metal CMOS
process, utilizing Actel’s PLICE antifuse technology. This
