I am an undergraduate at the University of Nebraska. I am interested in VLSI, but my program doesn't have any related courses. Because of this, I am writing a proposal for an independent study course in VLSI in which I will have to design and have made an original IC. Here's where I need help: From my readings of the net, it is my understanding that MAGIC is an LSI CAD program that runs on a PC and will generate the masks for the IC. If this is so, could someone please tell me who makes this software and a rough idea of its cost. Also, I would like to know if there are any other such programs available (name of program, manufacturer, approx. cost). Finally, I will also need to find a text for this course. I do have all the info on the VLSI texts that has been posted to this group in the past couple of months. If anyone could make any other recommendations it would be greatly appreciated. Even if it is an old text, I could use it for a comparison. -- ------------------------------------------------------------------------------- | Stephan G. Kleine | I have nothing more to say.

I not an expert on MAGIC (UC-Berkley), so I'll let someone else help you with that, but a few words of caution. I used MAGIC as an undergrad in 88 in a VLSI design class. We started with a clean slate: no standard cell library, no memory blocks or generators, no existing layouts. We were supposed to design a 16-instruction microprocessor with 4-channel I/O. We had MAGIC for layout, Crystal for simulations (or was it for static timing?), that was about it. Far too much work for 5 people to accomplish in 6 months! So do it right: First, select a manageable project. We spent 3 months getting the architecture and RTL simulator working! Second, get a switch-level simulator to do gate-level designs (I'm assuming you choose a digital application). Get a library of standard cells (pre-built primitives that you can throw down and simply wire up). If you use memory blocks, don't try to design them yourself, that's a project in itself (as we learned :-). Try to get a simulator with a decent front end. Crystal was horrible to use because of this, tho I suspect it's been improved since then. Try to find a routing tool (MAGIC probably has one) to help you with this. We didn't and found it EXTREMEMLY time consuming. Finally, save youself a lot of headaches and make sure you have adequate documentation for the tools that you use! > Finally, I will also need to find a text for this course.

Covers basic IC design approaches, logic entry and verification, graphics requirements (CAD side), physcial design tools and processes (place and route, error checking), solid state device basics, device modeling and simulation, MOS circuit design, design libararies, memories/PLAs, test issues, back-end tools. Phew! Like I said, a little of everything and good exposure to the overal process. "Design and Analysis of VLSI Circuits", Glasser & Dobberpuhl, Addison-Wesley, 1985. Sort of the bible of VLSI, everyone I work with has one. More detail on circuit related issues, little emphasis on CAD tools. I would highly recommend it for VLSI design. "Introduction to MOS LSI Design", Mavor, Jack & Denyer, Addison-Wesley, 1983 Don't know what your background is, but makes a nice, short introduction to CMOS processes and design, with detail on layout issues and some coverage of CAD tools. Terse and very practical.

I want to thank everyone that responded to my request for info on LSI CAD programs available for PC's. I got a lot of good help and advice. ------------------------------------------------------------------------------- | Stephan G.
