SI/PI Simulation:
Topscom SI simulation team has 20+ years of experience in DDR4/DDR3/ DDR2 parallel bus and high speed serial bus simulation such as PCIE、SATA、SAS、SFP+ and 10G-KR. We provide suggestions to design the proper topology, select the best termination and driver, and optimize the whole channel to get the lowest loss and best eye open. We also have DDR4 and 56G-PAM4 signal design and simulation capabilities.
