A novel power plane with super-wideband elimination of ground bounce
noise on high speed circuits," IEEE Microwave and Wireless Components Letters, Vol.
When a ground bounce
occurs, the ground voltage on the tool may be significantly different from the one on the connected computer or another tool.
is most problematic when several signals switch at the same time or when using high-speed drivers, both common with parallel data busses.
The results are displayed as a graphical 3D animation dynamically simulating the real-time ground bounce
effects of actual device operation across the powerplane.
There are three important criteria on which to base a decision: sensitivity to ground bounce
noise, highest data rate supported, and power dissipation.
Higher signal speeds and increased board densities often lead to signal integrity issues such as crosstalk, ground bounce
, and ringing that manifest themselves in functional failures of the digital system.
Chosen for "best" awards were papers in the fields of CAD, tools, and test; they deal, respectively, with digital ground bounce
reduction by phase modulation of the clock; poor man's TBR--a simple model reduction scheme; and wrapper design for testintg IP cores with multiple clock domains.
When you consider all the different effects lumped under the term signal integrity, it seems like there is a neverending list of problems to keep track of: ground bounce
, ringing, crosstalk, switching noise, rail collapse, delta I noise, capacitive coupling, reflections, discontinuities, impedance miss matches, lossy lines, terminations, branches, deterministic jitter, stubs, decoupling capacitors, loop inductance, via inductance, controlled impedance, time delay, skin depth, return current, layer transitions, differential impedance, collapse of the eye, common signal termination, differential signal termination, overshoot, intersymbol interference, ring back, etc.
The most common problem affecting stability of digital in-circuit tests is ground bounce
between the device-under-test (DUT) and the test system.
The normal SCSI single ended interface has a signal return ground for each single line reducing ground bounce
Rieper refereed an hour-long training ground bounce
match on Saturday in which Larsson saw his first action since suffering a horrific leg break in Lyon last October.
