I'm just getting into FPGA design. What are good FPGA vendors in terms of good chips, good tools and good support?
Also, if you've used the Cypress PSoC mixed analog & digital chips & tools, how did you find them?

Not claiming wide or deep knowledge of this subject but the Spartan 3 Starter Kit
Their Webpack software suite is on the CD with the starter kit or available as a (large-ish) download.

The two major vendors in the market today are xilinx and altera who produce roughly equivelent devices from simple pals to system on a chip scale fpga'a with all the design/simulation software provided. There are differences in the design of the fpga's between to the two manufacturers and my opinion is that xilinx produce the more sophisticated devices with features such as 18x18 hardware multipliers ,multiple i/o standards and core voltages as low as 1.2 volts they are however corespondingly more expensive.Altera devices are similar but I always get the feeling that they are always one step behind in producing new features.Other manufacturers are firms like Cypress,philips etc
Start here
The two big vendors are Altera and Xilinx

philips ? Philips sold their cplds to xilinx, see coolrunner2 and xpla / coolrunner
others include Actel , Atmel , Lattice , for a list of manufacturers

While Xilinx and Altera are probably slated as the "two major vendors", there are still very good offering from companies like Actel
Each have their own postiive and negative attributes. Each have their own flavors of engineering boards. Some have higher speed units (Actel offers parts approaching 500MHz speeds), etc.

The one that I know of that's really different is Actel, which produce FPGA's based on non-volatile memories, either EEPROM or anti-fuse (the others are all RAM). The non-volatile aspect gives an advantage for some applications because they are instant-on, unlike a RAM-based part which must be configured. They are also much more sensitive to the needs of the military/space/aviation customer.
However, the design flow for an anti-fuse part becomes much more like an ASIC, with much greater attention being needed for verification because a boo-boo means burning and turning a chip, rather than just loading up a new configuration.

Did I saw philips? sorry Ive got them on my mind at the moment:)
Chris:
Atmel offers 32 MC, 64 MC , 128 MC CPLDs -ATF15xx Family for 5V,
3.3 V Applications. If you need an 8-bit Micro + FPGA look no further than the FPSLIC ; Atmel has a Tools Promo- 50% off for FPSLIC .
While I love Atmel's AVR chips, their licensing costs for System Designer or the FPGA syntesis packages are way too expensive for us little guys as compared to similar offerings from Altera or Xilinx.

Get an STK594 $99 (or is it still half price?). Write two app notes per year, and you have a free license for ever... It will be extended for 6 months per app note
