Implementation and prototyping of a complex multi-project system-on-a-chip

A silicon prototyping methodology is presented for Multi-Project System-on-a-Chip (MP-SoC) implementation. A multi-projects platform was created for integrating heterogeneous SoC projects into a single chip. The total silicon prototyping cost of these projects can be greatly reduced by sharing a common platform. To demonstrate the effectiveness of the proposed methodology, a MP-SoC chip was implemented with eleven SoC projects sharing the common platform. The total silicon area is about 37.97 mm² in the TSMC 0.13 um CMOS generic logic process technology. Compared with the total chip area 129.39 mm² by implementing these projects separately, the results show that there are 91.42 mm² silicon areas reduced by the MP-SoC platform. In order to verify MP-SoC through silicon prototyping, a system modeling and hardware/ software co-design virtual platform were implemented. A configurable SoC prototyping system, namely CONCORD, is also created as a verification platform for emulating the hardware of MP-SoC before chip being taped out. The CONCORD system provides higher connection flexibility, modularization, and architecture consistence than conventional FPGA systems.
