I need to do a quick design with a CPLD - estimate is 128 cells with 64 I/O pins. I don't really want to buy design software unless it is cheap and I know some of the vendors are doing limited spec free versions.
Are there any experts on here who have evaluated what is currently available and could point me in the easiest direction? Thanks!
No expert I, but Lattice ISPLever and Xilinx Webpack spring to mind. Both free and downloadable (though registration is a pain). Unless you've got a lot of patience and fast broadband I'd try to dun a CD out of the local sales force.
If you are looking for small quantities (so that component price is not too important), then there are lots of manufacturers, and most have free software. You still have to buy some sort of jtag-type download cable for programming them, however, and you might find the easiest and cheapest way is to get hold of a starter kit or small development kit.
Personally, I'd go for Altera, because I think their tools are better than the (old) Lattice software I've used, and the Xilinx software I tried out.
