Through these means of reverse analysis, Shenzhen OROD technology can help customers understand the design of other products for the project feasibility study, opening up ideas, finding problems, cost accounting, etc. For example: before entering new fields, evaluate and verify the feasibility of their technical solutions and design ideas; through the study of mature products on the market, help solve critical technical problems. Use the market resources of existing products, reduce barriers to entry, achieve better product compatibility and so on.
The reverse analysis mainly used in the study of integrated circuit technology, patent analysis, chip imitation, and other different aspects; different applications have different design processes. Chip copying is to use reverse technology to complete a complete chip design, and its operation is the most complete. To let readers understand the reverse analysis process more comprehensively, the following will take chip copying as an example to introduce the reverse analysis process in detail.
Chip pre-processing is the essential step of the reverse analysis, which includes packaging removal, core dissection, image acquisition, and image processing. Through pre-processing, chip image database containing all layout information of reference chip can obtain.
Network table extraction is based on chip image to identify various layout elements such as units, interconnects and so on, and get the process of chip network table. The extracted chip network tables usually contain a series of analog devices and basic digital units, as well as the connection information between these devices and unit ports. Network tables are generally described in the form of text files, and can also convert to the graphic graphic graphic form of planar circuits. A kind of for the extracted network tables (or planar circuit diagrams), it is also necessary to analyze the circuit arrangement, transform them into hierarchical circuit diagrams under the premise of ensuring the same circuit connection relationship, restore their original design architecture and functional modules, so that we can understand the design ideas, design techniques and design characteristics of reference chips. After the circuit is sorted out, circuit or logic simulation is needed. The correctness of network table extraction can verifi by simulation, and the deviation of device parameters caused by process transplantation can also be corrected. Chinese style layout design refers to the process of drawing a layout according to the design rules of the target process, referring to the background of the image. It is an essential and unique link in chip imitation. After the layout drawing complet, LVS verification with the network cable is also needed to find errors in the extraction or layout drawing of the network table, to improve the success rate of chip copying. At the end of layout design, post-simulation of the layout is also needed to verify and optimize the performance of timing and power consumption after layout transplantation. A kind of after the above work completed, it will enter the chip manufacturing link. This part includes mask fabrication, chip production, chip packaging, and chip testing.

IC Reverse Analysis/Reverse Design
At present, due to the weak research in the field of the analog integrated circuit design in China, chip reverses analysis has become an effective way for most analog mixed circuit engineers to accumulate experience based on actual analog circuits. IC reverse design has also become an effective means to promote the progress of internal integrated circuit design.
In IC reverse analysis and design services, OROD Technology mainly provides the following services:
Modification of IC Circuit with FBI
Physical change of the chip circuit with FIB can enable the chip designer to test the chip problem more quickly and accurately, to verify the design scheme more accurately. If there is a problem in some areas of the chip, the function of this area can be isolated or corrected by FIB to find the crux of the problem. FIB can also provide some samples and engineering chips before the final product mass production. Time to market for fast terminal products. Using FIB to modify the chip can reduce the number of unsuccessful design modifications and shorten the development time and cycle. For the customers who do chip decryption, the effect of decryption can achieve through line modification.
Reverse and Safety Analysis of Single Chip Microcomputer, CPLD, and FPGA
The microcontroller, CPLD, and FPGA chips are analyzed and tested, and the reverse code extraction and security vulnerabilities test and analyzed.
IC Section Analysis
FIB is used to make cross-section fault at the specific position of the IC chip. The cross-section structure and material of the material analyzed at a fixed point. IT can help IC designers to explain the performance of IC design.
Network Table/Circuit Diagram Extraction and Logic Function Analysis
In chip reverse engineering, network table/circuit diagram extraction is critical. The quality and speed of network table extraction directly affect the work of finishing, simulation and LVS. OROD Technology has successfully summarized a set of practical norms and methods in long-term technical research, which can extract network tables of various types of circuits with high quality and high speed.
