Research Of Verification Methodology Based On LCD Controller Monolithic

At present, the demand of consumer electronics product has been growing a lot, such as mobile phone, personal digital assistant and digital camera. This trend not only increases the Liquid Crystal Display market, but also brings a bright prospect for LCD Controller. Due to the continuing increase of function, LCD Controller has becoming more and more complicated, so the difficulty of verification also presents an index rise.All popular verification method is mainly discussed in this thesis, and a full system verification methodology based on LCD Controller monolithic is proposed here. Register transfer level code verification is the most important factor in the design, therefore, two ways are analyzed in this thesis: logic function simulation and prototype verification. In the first way, code static check could be used to guarantee the coding style. After the detailed research of design specification, a reused verification platform was constructed using bus function model, programmable language interface, etc. The analysis of coverage is necessary for the platform. FPGA is used in the second way for emulation, to assure the chip function under real circumstance.Many design flows are required in the modern ASIC design, every flow can bring mistake and performance degradation, so how to verification netlist and layout in the design flow is also discussed in this thesis. For gate netlist, formal verification, static timing analysis and dynamic post-simulation are used to assure function correctness and timing closure. For physical layout, the main means are design rule check and layout vs schematic. The more and more complexity of chip manufacture lead to the reduction of finished semiconductor device rate, so chip test is necessary before sale. For the LCD Controller, two silicon verification ways are proposed: scan test and memory built-in self-test.
