The direct and single ground bounce
returns are observed to be present in the measured results.
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.
Undesired analog effects associated with parallel data busses such as crosstalk, ground bounce
, ringing, and clock skew have become major design constraints for the Ultra ATA interface, which is forced to maintain compatibility with legacy parallel technology.
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.
Such noise is typically generated by ground bounce
, radiating signals or even by the digital device itself.
Some specific topics examined are fault diagnosis and fault model aliasing, reducing peak current and power during test, an IR drop and ground bounce
awareness timing model, and using the nonlinear property of FSR and dictionary coding for reduction of test volume.
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.
