Julin Launched PowerExpert - a GUI-based Tool for Power electronics System design and Simulation

With the development of VLSI (Very Large Scale Integration) technology, the voltage of the chip is getting lower and lower, while the speed goes faster, the power consumption is getting larger, and the density of the single board is higher. Therefore, stability of power supply system in the bandwidth faces a huge challenge. The quality of power integrity (Power Integrity) directly determines the consistency of the data transmission sequence. Any flaws in design may lead to functional errors in the system, so the design of power integrity directly affects the performance of the system, such as machine reliability, signal-to-noise ratio, bit error rate, EMI/EMC and other important indicators. Therefore, in the the design process of electronic system, the choice of the power supply scheme is significant. The power supply scheme with high reliability and superior performance is a guarantee for the safe operation of the entire electronic system.

Focusing on the application of signal and power integrity, Julin has launched a GUI-based tool which for power electronics system design and simulation, PowerExpert.
