System performance comparisons of coreless and standard packages for data rate beyond 20 Gbps

This paper analyzes the impact of standard and coreless packages on the overall high-speed system performance for data rate beyond 20 Gbps. Instead of focusing on package electrical performance in isolation, we study the package impact on the system performance metrics such as voltage and timing margins and bit error rate (BER) bathtub curves in both time and voltage by employing statistical system simulation methods. Furthermore, the package impact on the quality of the power supply network is also studied using conventional frequency and time domain simulation techniques. Finally, three designs with standard and coreless packages are analyzed to compare the package impacts on signal integrity and power integrity of high-speed systems.
