Verification And Testing Of An Interface Chip Based On PCI

The most complicated and the most time-consuming step is verification and testing in IC design processing. Because the percentage of IC's function verification and testing is 60% to 70% in the whole develop at present, it is obviously the key. So our job is trying to verify and test complex IC so that shorten develop period. The way is to set up powerful simulation platform in every design stage to increase automation level and the efficiency of verification and testing, ultimately, the IC development cycle is getting shortening.This paper is based on PCI bus,which presents the PCI bus interface chip verification methods and test methods, so that it builds verification and test platform, moreover, it improves the efficiency of the verification and testing. The verification and test methods which this paper is going to mention can also be used for other PCI-related chips. According to the project requirements, first of all, the principle of simulation-based verification is to build RTL verification platform, by using of ModelSim, simulation testing is processing. What's more, the FPGA verification platform is build by use of Xilinx's XC3S1500FT456 chip. FPGA logic function verification provides more comprehensive verification; it facilitates to check potential errors. Finally, in order to test chip functionality, a PCI bus interface chip test platform is built, and the design uses HHNEC0.35μm chip tape-out. Besides, chips supporting drivers and test software are developed in the Windows operating system, which apply to FPGA simultaneous verification and testing as well.
