There you go. You would obviously need at least some prior experience before you can get down and dirty with IC production. It is not as easy as learning how to brew coffee but it requires some expertise on a certain level. Yes, anyone can fork out that amount of money to make one but would they get the same incredible results? I highly doubt that. Perhaps there could be better explanation on that portion so as to avoid confusing people who are really keen.

I did this in a class in 1994
I did this in a chip-design class in 1994, using MOSIS and MAGIC and 10-micron technology. I offered to do an analog design all by myself, but the instructor preferred that I partner with another student, so I did a digital project. The university was a few miles from a large chip-fabrication plant, so knowledgeable instructors were readily availabe.

My first Linux distribution, from Nascent Technology in 1994, was aimed at this application and had many open-source chip-design packages. MAGIC was on there, as was a French VHDL-to-chip digital design package. Their ads proclaimed, "Cheap Chip".

Re: Great Blog and comments
Hi, Scott, yes, your mention of legality is also valid in India, though I am in India,most of my work are for countries where legal systems are more rigid.Even open tools are also helping me. But while giving lectures at apex instutions I found the ignorance of using Open EDA tools is dominant. 

I am still many steps behind true desktop mixed signal ASIC design/verification, but I look forward in teaming up for sharing of knowledge and re-distributing it for the younger generation.

Looking forward

Thanks

Hello Adipudtt,  I suppose if one uses tools provided to Universities for doing commercial products, I can accept your claim that no one would use cheap tools.  In the US, Canada, Europe, Japan, etc. that is not a legal option, so the blog points about tools remains relevant.  Even more so today.

Look me up on line if you want to team up!

Scott

Re: Re : Design a Custom Analog IC in Your Garage
I have been using a UK package,  made by Seetrax, XLDesigner, for 25 years now. I also use Orcad but only for simulation. It is asmall company and gives great phone support and the package never crashes. I do alot of adding tracks inthe layout, copying and pasting and the package can always figurw it out when I do an eror check. What would take me aweek to do in Orcad i can do in a day with this package. So easy you don't mind reding huge sections at the end.

Great Blog and comments
Came up on this grat blog pretty late. I was doing 1.8u (yes that is very big) in 1998, in 2001 joined a fabless company and became an architect of the chip that fired up the first hard-disk version of iPod. Now I am in India and believe me with all the tools and free tools given to Universities, no one wants to go for this kind of work. I think it is because doing analog with a few gates thrown in silicone really needs hardwork and most people - they are better of doing Software. 

I am forwarding this blog and some of the excellent comments, thanks Scott, and I am ready to team-up (at least techinical discuss)of setting up full system design on a desk, or let us say three desks

Thanks for an answer that gives us a continuum of the cost-time consideration.

"How do you rate the tool compared to the Cadence layout editor ?"

No comparison.  One costs $100,000.  The other $100.  If you have more money than time, buy Cadence.  If you have more time than money, spend $100.

What extra features Juspertor compared to the free-tools ?

I think it is more user friendly.  It supports Open Access.  And there are different levels of purchase with lots of users.  I think that is good from a support standpoint.

I learned of another tool the other day from http://www.symica.com.  It isn't cheap, but they claim it is compatible with Cadence.  Their price is in the middle.  That means consider that product if you have some money and some time. :-)

Re : Design a Custom Analog IC in Your Garage
Free design tools can be found, but you might want to consider spending $100 on at least the layout/schematic tools (like Juspertor) to simplify verifications between your schematic and your layout.

@Scott, thanks for the post. I have used Magic layout editor and I find it pretty difficult to use because user interface is pretty poor. I have never used Juspertor. How do you rate the tool compared to the Cadence layout editor ? What extra features Juspertor compared to the free-tools ?

More Blogs from Scott Elder
For those who aren’t familiar with the term vaporware, it simply means hardware or software that is heavily promoted, but not for sale. Like any vapor, it exists only in air. This seems to be the case with narrow band Long Term Evolution (LTE) modems for the Internet of Things (IoT).
>“First to invent” is a term of art used under previous United States (U.S.) patent law to define who deserved a U.S. patent. Regardless of your opinion about the recent U.S. patent law changes, from a practical sense it is very hard, if not impossible, to define who is the first to invent anything.
The world has been told that LEDs are the future, in part because they are economically the right form of long-term lighting and there are environmental benefits as a great aside. Well, maybe the environmental argument is true, but the economical one is not.
After countless years designing analog ICs, Scott Elder still stresses out on four key days during a product development cycle.
The evolution of technology is being hindered by the lack of high-end tool access. Most innovation originates from small organizations with little or no money to pursue their visions.
