Hi Jim - You wrote: At some point, multiproject wafers (like MOSIS) might become a hobby product. So far, it's in the "several kilobuck" minimum purchase, and, as well, the tools aren't easy to come by. Or, more properly, good design tools are expensive, tedious design tools are free.. you CAN layout an IC for MOSIS with a ruler and and a quadrille pad.. get your copy of Carver and Mead and have at it)
I assume that you mean Carver Mead and Lynn Conway, Introduction to VLSI System Design 1978. I am enjoying this thread!

"leaders in the trailing edge" (no kidding, that's their slogan).. They buy old fabs, masks, etc, and keep producing small runs of older parts. For a price.

The same is not true for analog. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
