gEDA-user: While we're bragging...

[John Doty <jpd@xxxxxxxxxxxxx>]

I received the following from the SPIE:

------
On behalf of the chairmen for the conference on “High Energy,  
Optical, and Infrared Detectors for Astronomy II” it is my pleasure  
to confirm acceptance of the abstract submission “An ASIC for delta  
sigma digitization of technical CCD video.”

High Energy, Optical, and Infrared Detectors for Astronomy II (6276)  
is part of the Astronomical Telescopes & Instrumentation meeting that  
will be held 24 - 31 May 2006 at the Orlando World Center Marriott  
Resort and Convention Center in Orlando, Florida USA.

This is a project I've been doing with gschem, spice-sdb, and ngspice  
(also Mathematica). It's nearly ready to go to the layout contractor:  
I'm finishing off the top level design and tweaking the low levels  
for best performance.  About 6000 transistors, and delta sigma  
converters need lots of clock cycles per conversion: simulating 1/4  
of it takes about 6 minutes per converted pixel on a 2.4 GHz Athlon  
64! Been running sims overnight, analyzing by day.

When I've written this up, I'll put it on line somewhere.

Thanks to all who contributed to gEDA! Now where's that web site for  
monetary contributions? Mathematica cost almost $2000, but for what I  
got out of it that's reasonable. gEDA was even more important...
