SIwave – DC: Engineers from Sarcina Technology LLC used ANSYS SIwave to extract DDR3 electrical models for both a PCB and its daughter card to analyze the performance of application-specific ICs used in Big Data applications and the Internet of Things. SIwave: LSI Corporation used ANSYS Chip Signal Model and ANSYS SIwave to show that voltage swings on the signal network of a DDR parallel interface circuit were coupling to the power supply of the PLL, resulting in phase error between the PLL reference clock and output clock. Additionally fast PCB and PKG characteristic impedance scanning was performed to quickly determine problems due to routing and stackup. SIwave – PI: Fully automated de-coupling analysis used to improve noise margins on signal nets due to power fluctuations caused by large transient currents ( ).
