I have a board which I am developing and am using a Dallas 80C320 with a ST PSD (Flash, CPLD, RAM etc). I also have a Lattice 2064 CPLD which is to be used to implement all of my logic (other than address decoding which the PSD can easily do).

Does any one here have any experience with the Lattice part and/or ispLever s/w ?

I've implemented a design that compiles and can be programmed into the device, but which does not work as expected (it's a simple 8 x d-type ff as a latch with tristate o/p's) it worked before changing to tristate o/p.

This may be a little off topic but any help would be much appreciated.
