| Abstract: | The paper covered the usage of Cadence tool for the PCB design of SDRAM memory interface in one of testing system. By simulating the critical signal nets based on IBIS model, the PCB design rules such as trace length and net topology were determined. This helped to improve the system performance, reduce the fail risk and development period. |
