Thanks, Phil, for supplying the pointer above. However, in my humble opinion the AMD brief is rather incomplete. There are other, better, sources of information on ground bounce: [1] IDT High Performance CMOS Databook (volume 1 of 2), Application and Technical notes, chapter 14. "FCT - Fast, CMOS, TTL-Compatible Logic", pp. 14-209..250 [2] EDN magazine, "EDN's advanced CMOS logic ground-bounce tests", March 2 1989 issue, pp. 88-114. {interestingly, some IDT devices didn't do well despite their excellent explanations contained in reference [1] !!} [3] Texas Instruments, "Advanced CMOS Logic Designer's Handbook", rearcover #SCAA001A. All of chapters 3 and 4 are good, but the best part is page 1-4 and 1-5 (Table 1.1-1 and Figure 1.1-1), where they give pin inductance vs pin position for several package types. [4] EDN Magazine, "Equivalent circuits model subtle traits of advanced CMOS IC's", by Charles Dike of Signetics Corp. April 14 1988 issue, also available from Signetics. -- -- Mark Johnson MIPS Computer Systems, 930 E. Arques, Sunnyvale, CA 94086 (408) 991-0208 mark@mips.com {or ...!decwrl!mips!mark}
