Can antifuse FPGA be reprogrammed?

Xilinx does not manufacture anti-fuse FPGAs. Anti-fuse based FPGAs use one time programmable elements (anti-fuses so named because the are normally open circuit and when programmed create a short circuit).

How FPGAs are programmed?

The designs running on FPGAs are mainly coded using Hardware Description Languages (HDL) such as Verilog, VHDL or SystemVerilog. An increasingly popular way to program for FPGA is High-Level Synthesis (HLS) in which the design is done in a subset of C and the compiler transforms the design into correct Verilog code.

What are the main programming technologies for FPGAs?

For commerical FPGAs, the main switch technologies are antifuses (e.g. Actel) and Static RAM cells (e.g. Xilinx). For commerical CPLDs (e.g. Altera MAX), the main switch technologies are Erasable Programmable ROM (EPROM) transistors and Electrically Erasable PROM (EEP- ROM) transistors.

Which programmable techniques are used in FPGA?

The following are three of the well-known programming technologies used in FPGAs.

• SRAM.
• EEPROM / Flash.
• Anti-Fuse.

How is an SRAM based FPGA different from an antifuse device?

An SRAM-based FPGA is a volatile device that must be initialized or programmed at each power-up cycle. This is not the case for antifuse-based FPGAs which are one-time programmable and non-volatile devices. An antifuse does not use a bitstream. This means that there is never a bitstream that can be intercepted, copied, modified, or corrupted.

Which is an antifuse programming technology predominantly associated with?

An Antifuse programming technology is predominantly associated with _____. a. SPLDs b. FPGAs d. All of the above Required! Required!

What is the 3.3 antifuse technology for Actel FPGAs?

3. 3 Antifuse technology for ACTEL FPGAs  An antifuse is the opposite of a regular fuse  An antifuse is a normally open (N.O) type of switch. A programming current of 5 mA through it closes the switch. e.g.

How are programmable logic cells used in FPGAs?

There are two classes of programming technology : [i] OTP (One time programmable) [ii] Reprogrammable Different FPGAs use different programmable (switching) elements : [i] Antifuse in ACTEL FPGA [ii] Static RAM cell in Xilinx FPGA [iii] EPROM/ EEPROM in Altera CPLD Programmable interconnect (PI) is used to connect any two logic cells.
