There are a few FPGA vendors, and
even more vendors offering FPGA-like
What follows is a list of several
companies and their main products.
If you find a company or major product
missing, please email me and I'll add it.
Only FPGAs (Fusion) with analog components
(A/D converters, ability to sink high currents,
ability to monitor voltage/current/temperature)
Only FPGAs with instant live-at-powerup, based on
Flash memory or one-time-programmable anti-fuse memory
Low power FPGAs
Very small FPGAs
Newest FPGAs: Stratix IV (40nm), Stratix III (65nm),
Cyclone III (low-end)
Recent FPGAs: Stratix II (90nm, high-end), Cyclone II (low-end)
With Stratix III, Altera adopts the same strategy Xilinx started
with Virtex 4 of offering several different devices in the same family.
Have purchased FPGA IP from a number of companies previously offering
FPGAs (eg, ATT/Lucent, AMD)
Small-to-medium size, low power
Newest FPGAs: Virtex 5 (65nm)
Recent FPGAs: Virtex 2/4 (high-end), Spartan 3 (low-end)
Since Virtex 4, Xilinx has divided their high-end into several
different devices, each containing a different mix of resources.
This is an attempt to match the needs of different market segments
with less waste.
