Abstract
This paper proposes a packet-based verification platform with serial link interface for emulating the hardware of the heterogeneous IPs before tape out. With the serial link interface Serializer/Deserializer (SerDes) added between IPs, significant amount of pin counts can be reduced in the platform. An adapter is inserted between IP and SerDes to convert parallel bus into packets and handle the handshaking. Under our proposed adapter architecture and handshaking scheme, the limitation on the number of the master adapter is eliminated compared with Bus-based Advanced High-performance Bus (AHB) architecture. Simulation results show the data transfer through our proposed architecture works correctly without the limitation on the number of masters. With the proposed adapter and SerDes architecture, the number of required signals in the interconnect is reduced from 79 to two for the AHB bus. ©2010 IEEE.
