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. |

The controller board based on ADSP BlackFin BF532 (LQFP176 package) have been developed for the simulator platform used in entertainment industry. For the purpose of influence minimization over circuit digital elements, additional protection design solutions have been used in connection with stringent electromagnetic compatibility (EMC) requirements determined by close position of platform strength elements. Special PCB trace routing methods have been implemented in external communication interfaces towards elimination interference effect from operating frequency converters and high-performance alternating current motors. |
