Hello,
I last used Electric in 2003. I've downloaded the latest version
8.08 and tried to create my own technology by editing the mocmos one.
I found that the sequence "Convert Technology to
Library for Editing..." followed immediately by "Convert Library to
Technology..." fails, even without any edits being made.
The issue here is that the MOSIS CMOS technology is too complex to
edit completely. The good news is that the two objects that are too
complex are not necessary. So after converting "mocmos" to a
library, you must delete the two cells that define the "scalable"
transistors: "node-P-Transistor-Scalable" and
"node-N-Transistor-Scalable". Then you will be able to convert the
library back to a technology.
I downloaded version 8.07, but was unable to open the two libs I
was trying. These are the dff_cells and muddLib07 libs from the web
site. The error is shown below.

Is there an easy solution to this problem? As I remember, back
in 2003 I failed to make my own technology and had to go elsewhere.
The program is looking really good now and I'd like to try it out some more.
I cannot say for sure why old libraries fail to read. Electric is
*supposed* to be completely backwards-compatible. If you would like
to send a bad library to me, I can examine it further.
