The DUT logic gate input, referenced to DUT ground, will see the ground bounce voltage Vlg as an input signal.
There are five important methods for reducing ground bounce and radiated emissions:
At the same time, the ground bounce, an effect due to fast switching activities, is becoming the bottleneck of high-performance chip designs.
Designers can locate the devices exactly where they are needed, improving circuit board routing, reducing noise, ground bounce, and Electromagnetic Interference (EMI).
40 can create test patterns that automatically limit the number of nets that switch simultaneously, thus reducing the likelihood of inconsistent test results due to ground bounce.
By identifying the precise locations of design weaknesses and their impact on dynamic voltage drop and ground bounce, RedHawk-EV allows designers to not only verify potential power-related functional and timing behavior, but also avoid excessive over-design.
The registers offer lower ground bounce and ring back, high current drive that can drive heavy signal loads and the flexibility to handle both low/mid range and high-end memory densities.
These models can be subsequently used for simulating complex problems such as Simultaneous Switching Noise and Ground Bounce.
To accommodate shrinking design cycles for complex high-speed systems, engineers cannot rely on board prototype analysis to uncover problems such as reflection, ringing, ground bounce, and crosstalk.
The different voltage levels may be intentional variations for power savings or the result of IR drop and ground bounce.
With AnsoftLinks v3, engineers seamlessly transfer their integrated circuit (IC), printed circuit board (PCB) and package designs into any of Ansoft's high-performance electronic products to analyze, verify and optimize electromagnetic-associated performance characteristics, such as ringing, reflection, ground bounce, simultaneous switching
This new configuration also reduces critical electrical performance parameters, such as ground bounce, to as little as one-sixth that seen in standard packages.
SIwave's proprietary full-wave, finite-element technique allows designers to characterize simultaneous switching noise (SSN), inter-symbol interference, power and ground bounce, resonances, reflections and coupling between traces and power/ground planes.
