James, I've been working with Lattice devices and software for several
years. The following is my `canned response' for folks asking about
Lattice:
--------

   If you want to design your own CPLD, Lattice provides the ispDesignExpert
software with a free 6 month license which is easy to renew for free. This
is an incredibly powerful free software suite. It provides schematic,
ABEL-HDL, VHDL, and Verilog entry. Also included is a gate-level functional
and timing simulator with detailed timing analysis and a waveform viewer.
There are too many features to list here. The starter software supports
their ispLSI (up to 600 Macrocells), ispGAL, MACH (formerly Vantis), GAL,
and PAL devices. There is a large library of device models (gates, counters,
etc). Using schematic entry, you can add pre-defined modules or make your
own from another schematic or using one of the above HDL languages. Or, you
can do the whole thing in HDL.

   Programming the ISP (In-System-Programming) devices is trivial with just
a 5V supply. The Lattice software to do this is free and is included in the
ispDesignExpert package or as a separate ispDownload program. The buffered
ISP download cable uses a 74VHC244 and a few passives and connects to a PC
parallel port. Most folks already have the parts in their `stash'. To build
the Lattice ispDownload cable, and see some simple designs that have been
tested with a PIC, see my web page at:
