All, This likely means that someone who has corresponded with both SI-List and the virus recipients has become infected. That person's machine is sendin= g emails with to-address and spoof from-addresses both gathered from its MS address book. The infected person has therefore at some stage sent or received mail to/from SI-LIST and _also_ to/from Tom and the other recipients. That should be a clue (assuming it's only one infected box). All list participants could usefully virus-check our machines... which of course we or our IT depts. should be doing anyway.

I have received another email supposedly from the SI-LIST with a very suspiciuos attachment. Are other people getting these?

If your goal is to use a static (or other) timing evaluator that uses mod= els based on the time delay of the parts in the databook, then it is importan= t that your SI measurement for test load be the same as the one used in the databook for definition of time delay through the part. What you are actually trying to do is remove the driving of the test load from the equation to avoid double counting of that part of the delay. jon -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]O= n Behalf Of C.Y. Cheng Sent: Friday, June 13, 2003 4:08 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] How do we choose the proper test load? Dear list members, I am confusing how to choose a proper test load for the timing evaluation. In the book=A1=A7High- speed digital system design=A1=A8 page 204. There = is an example: =A1=A7 An output buffer with an edge speed of 300ps is driving a transmis= sion line with a C11 of 2.5pF/inch. And propagation delay of 150ps/in., the ed= ge would encompass 2 in. or 5pF. Subsequently, a good load in this case woul= d be 5pF.=A1=A8 In this case, does the loading of receiver need to be considered to evalu= ate the Tco if the trace length less than 2 inches? This often asked by the logic designer. A capacitor often set at output p= in to extract timing for static timing analysis. The trace length in this ca= se may vary from 0.5 inch to 6 inches or more. How do we choose the test loa= d to cover all the case? =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D C.Y.
