Chuck: Chip design is an area of law covered by "patents", not copyright. Different laws, different rights & obligations. JHoagland: You have my message spot on. If you are going to do somoething that companies such as DAZ would like you not to - you had better be sure that you know what you are doing. I am not a lawyer - taking my advice is not a good idea. For all YOU know, I'm making it up on the fly! One the biggest problems with lititgation is that it is a game you can really only play if you have money. --EK
