Since we can determine and cope with impacts of IR drop (voltage drop) that occurs in resistance components of the board, power source impedance characteristics, or simultaneous switching noise in the design stage, we are able to develop highly reliable products. Such power source noise increases jitters in high-speed signals, degrades the reliability of signal waveforms and further leads to generation of common mode radiation noise. Reduction in power source noise is effective in improving the electric characteristics of a system. Kyocera supports reliable product design through our long experience in board design development for various fields.
IR drop analysis
We visualize the current distribution and voltage distribution of power supply patterns. Because we can identify the presence of voltage drop and current crowding around high-pin-count BGAs, power planes and via count can be optimized at the design stage, enhancing stable operation.
Power supply impedance analysis
We analyze the power supply impedance on frequency bands over 1GHz, and power/GND shapes and bypass capacitors are optimized if there is a resonance point. Modeling with wire bonding inside the package etc. is also available.
Analysis of low-frequency power circuit
We perform analysis of MOSFET switching noise generated by the motor control circuits like inverters, and impedance analysis on low frequencies (DC~few Hz) This is one of the new analysis issues in recent years.
