DSD Report Introduction of Actel FPGA

Outline Overview Actel FPGA Characteristic Actel FPGA Architecture Actel FPGA Application

Overview SRAM vs. Flash Fuse vs. Anti-fuse

FPGA Introduction To FPGA

SRAM Advantage: –Re-programmable (erasable) –Faster (than Flash) Disadvantage: –Volatile –Extra ROM –Need time for reading programs from ROM –Poor Information Security

Flash Advantage: –Re-programmable (erasable) –Non-volatile –Information Security Disadvantage: –Slower (than SRAM)

Fuse Resistance changes from Low to High when high voltage Programmed only once

Anti-fuse Resistance changes from High to Low when high voltage Require a very small area –More connections than others technologies Programmed only once
