The Future?
People often ask, “ Would you encourage your son or daughter to go into engineering? ” I
reply, “ Yes, if it is analog circuit design. ” They say, “ Explain! ”
I respond, “ My friends and I know many analog design techniques, tricks, and secrets.
They cannot be learned from SPICE. Every year there are 200,000 Chinese engineering
graduates, and they don ’ t know what we know. We can solve problems they cannot. ”
I rest my case. /rap

P.S. One of the authors of a chapter in this book said that he took a “ well-designed ”
system and put a good model of it into SPICE. When he ran it, he was surprised to find a
sneaky sampling error. So we should not say that SPICE cannot be helpful. We just have
to be cautious about trusting SPICE—in any positive or negative way.
