We developed topology and PCB layout design for graphical processor unit. Promwad engineers have performed preliminary modeling of high-speed signals by IBIS-models to define the way of signals termination. After modeling PCB designers have defined optimal solution for signals termination. PCB layout was performed according to trace lengths and skews. Special attention was paid to power supply and ground layout. Image
