Hermann Ruckerbauer, Owner of 'EKH - EyeKnowHow' has over twenty years of experience in high speed measurement and simulation especially on DRAM related interfaces. EyeKnowHow is serving the industry with consulting, simulation, measurements and training for all kind of high speed serial interfaces. Hermann Ruckerbauer is Keysight “certified engineer” due to his experience in working with Keysights ADS simulation environment. After receiving his Bachelor Degree in Micro System Technology from the University of Applied Science in Regensburg he was doing design analysis and application testing for several memory generations at Siemens/Infineon. His latest activity before founding his own company was the definition of the DDR4 signaling standard within JEDEC for Qimonda. With the background of DRAM internal functionally, system application requirements and high speed signaling he is supporting any kind of high speed interface implementations (e. g. for 10G Ethernet, PCIe, SATA, USB, ..) with focus on memory standards. Holding many patents he was award in 2005 from Infineon in the category 'Outstanding Single Patent' for the patent on the “Temperature dependent Self Refresh” in DDR Memory devices.
This article shows the impact of using one of the first DDR4-3200 FPGA memory controllers, the Xilinx Versal, interfaced to a UDIMM to show a method for accurately correlating signal integrity simulations to measurement.
