[SI-LIST] Re: Plane breaks - Benchmark report download

I've been bitten by the si-list line wrap - sorry guys.  The link should =
be
continuous and not have the "=3D" sign in it.

Thanks,

Subject: [SI-LIST] Plane breaks - Benchmark report download

Hi all,

Recently there have been extensive discussions on the effects of traces
passing over plane breaks.   As a matter of fact, a series of tests on =
the
effects of trace passing plane breaks  were conducted at Sigrity, and =
test
results were compiled in an internal report (written about 3 years ago)
which can now be shared at:

http://www.sigrity.com/support/internalbenchmark/traceoversplit/TraceOver=

SplitPlane.pdf

These tests demonstrate the impacts of plane breaks which include:

-Signal integrity degradation on active lines
-Increased coupling between adjacent lines
-Noise generated between metal planes
-Both microstrip and stripline structures are included

These tests were carried out by numerical solution of Maxwell's =
Equations
with 3-dimenstional finite-difference time-domain (FDTD) method. =
Sigrity's
SPEED2000 solutions of the same structures were also provided and =
compared.

For those of you who have SPEED2000, you are welcome to request the
SPEED2000 data files (spd files) for the test cases presented in the =
report.
Once you get the data files, you can revise the files to fit to your own
test case structures.

Best regards,

Sam
