The Research And Design Of Verification Platform Of TD-LTE Baseband Processing Chip

Baseband processing chip, the core part of home eNodeB system becomes a research hotspot,while mobile communication entering Long Term Evolution era. The complexity of LTE basebandsignal processing results in the large scale and complexity of femtocell baseband processing chip,making the verification of the chip very hard and complex. The research of verification methodmakes we will more likely to succeed in tape out, which is very important in aspects such asimproving the success rate of chip flow, predicting speed, area and power of the chip.This paper is based on the Institute of Computing Technology, Chinese Academy of Sciences’sproject "The development and industrialization of TD-LTE femtocell baseband processing chip".Based on systemetic research of mainstream chip verification methods, we carried oncomprehensive, multi-level and systemetic verification of TD-LTE femtocell baseband processingchip mainly with two methods: software and hardware co-verification, FPGA prototype verification.Our work mainly includes the setting up of hareware verification environment, simulatedverfication based on VCS and prototype verification based on large scale FPGA. During theenvironment settup process, we gave the details of the setting up compiling environment of thephysical core part of base band chip--soft kernel of OpenRISC processor. Then we designed andsimulated main modules of the chip with VCS simulation tools, verifying the functionality of eachmodule. At last we ported the whole chip design module onto FPGA platform to do prototypeverification, ensuring the correctness of the entire chip and guaranteeing the success of flow chip.
