mosis europractice

In a previous job position I have been doing analog IC design and layout using Cadence and Mentor tools.

Analog IC design and layout is no longer part of my job scope, but I am still interested further working on this in my spare time and would like to devise some circuits to run in MPW at MOSIS or Europractice.

I have been looking into the appropriate tool for this, taking into account my limited budget (since this is more of a hobby than of any commercial activity). I found L-Edit to be a very good tool, a complete suite with the required foundry support. However, this of course is still a reasonably large expenditure. I also found Magic and this also seems to be supported by e.g. the MOSIS program.

So my question is: does any one have any experience (related to the useability of the tool, to any errors encountered when going to fab, any other issues...) with using Magic for MPW runs with medium complexity circuits? And would one generally advise to use a tool like Magic or would it be more advisable in any case to use a tool like L-Edit?
 

mosis technology files for electric vlsi tool

why not ask mosis directly? support@mosis.com or **broken link removed**. you're more likely to get feedback from people who may have experience with ledit/magic via the user group.

Thanks, will do!
In the mean time, if anyone is willing to share his/her experience in this matter, I'd appreciate that highly.

I have no Idea anbout Magic. Concerning LEdit and Tanner's tools in general they are reliable and very accurate. In our laboratory we use tanner (with AMS libs) and no bugs were found in the tool.

You should check out Electric VLSI. It doesn't come with foundry support but with some effort, I suppose, you can build your own technology file. I am not sure about the simulator though, If you need BSIM3v3 then you can try some of the free tools that supports it but don't expect tight integration between them.

Free IC related tools:

Magic VLSI (*nix)
Electric VLSI (Java)
Alliance CAD (*nix)
LASI (Windows)
Microwind (Windows)

Berkeley SPICE
Linear Tech Switcher CAD
 

vlsi lasi vs magic

I am using LayoutEditor now (layout.sourceforge.net) and I am very happy with it. It is very complete and flexible. It does come with a small learning curve, but once there it is a very powerful tool.
 

magic ic design tools

The latest Magic version is great and it works gr8. But am not comfortable using ngspice for spice simulation. I have to tweak the netlist to suit it. gEDA is another tool and useful for schematic design..
