Military ProASIC3/EL Device Family Overview
reduce cost and design risk while increasing system reliability and improving system initialization
Reduced Cost of Ownership
Advantages to the designer extend beyond low unit cost, performance, and ease of use. Unlike
SRAM-based FPGAs, flash-based military ProASIC3/EL devices allow all functionality to be live at
power-up; no external boot PROM is required. On-board security mechanisms prevent access to all
the programming information and enable secure remote updates of the FPGA logic. Designers can
perform secure remote in-system reprogramming to support future design iterations and field
upgrades with confidence that valuable intellectual property cannot be compromised or copied.
Secure ISP can be performed using the industry-standard AES algorithm. The military ProASIC3/EL
family device architecture mitigates the need for ASIC migration at higher volumes. This makes the
military ProASIC3/EL family a cost-effective ASIC replacement.
Firm-Error Immunity
Firm errors occur most commonly when high-energy neutrons, generated in the upper atmosphere,
strike a configuration cell of an SRAM FPGA. The energy of the collision can change the state of the
configuration cell and thus change the logic, routing, or I/O behavior in an unpredictable way.
These errors are impossible to prevent in SRAM FPGAs. The consequence of this type of error can be
a complete system failure. Firm errors do not exist in the configuration memory of military
ProASIC3/EL flash-based FPGAs. Once it is programmed, the flash cell configuration element of
military ProASIC3/EL FPGAs cannot be altered by high-energy neutrons and is therefore immune to
them. Recoverable (or soft) errors occur in the user data SRAM of all FPGA devices. These can easily
be mitigated by using error detection and correction (EDAC) circuitry built into the FPGA fabric.
Advanced Flash Technology
The military ProASIC3/EL family offers many benefits, including nonvolatility and
reprogrammability, through an advanced flash-based, 130-nm LVCMOS process with 7 layers of
metal. Standard CMOS design techniques are used to implement logic and control functions. The
combination of fine granularity, enhanced flexible routing resources, and abundant flash switches
allows for very high logic utilization without compromising device routability or performance.
Logic functions within the device are interconnected through a four-level routing hierarchy.
Advanced Architecture
The proprietary military ProASIC3/EL architecture provides granularity comparable to standard-cell
ASICs. The military ProASIC3/EL device consists of five distinct and programmable architectural
features (Figure 1-1 on page 1-4 and Figure 1-2):
• FPGA VersaTiles
• Dedicated FlashROM
• Dedicated SRAM/FIFO memory
• Extensive CCCs and PLLs
• I/O structure
The FPGA core consists of a sea of VersaTiles. Each VersaTile can be configured as a three-input
logic function, a D-flip-flop (with or without enable), or a latch by programming the appropriate
flash switch interconnections. The versatility of the military ProASIC3/EL core tile, as either a three-
input lookup table (LUT) equivalent or a D-flip-flop/latch with enable, allows for efficient use of
the FPGA fabric. The VersaTile capability is unique to the Actel ProASIC family of third-generation-
architecture flash FPGAs. VersaTiles are connected with any of the four levels of routing hierarchy.
Flash switches are distributed throughout the device to provide nonvolatile, reconfigurable
interconnect programming. Maximum core utilization is possible for virtually any design.
