Automated generation of integrated circuit designs and test plans
A recently granted patent (Publication Number: US11922101B2) outlines a method and system for efficiently designing and testing integrated circuits. The method involves receiving a design parameters data structure containing values of design parameters, generating register-transfer level and physical design data structures based on this information, creating a test plan, and executing tests to obtain results. Additionally, the method includes automatically generating documentation for the integrated circuit and a field programmable gate array emulation data structure. The system described in the patent comprises a memory and processor that work together to carry out these functions, including updating the design parameters data structure based on test results and generating the design parameters data structure through a web application.
Furthermore, the system detailed in the patent includes a web application server that generates the design parameters data structure based on user input, displays an auto-updating block diagram reflecting changes to design parameters, and issues commands to build the integrated circuit design. A controller within the system accesses this data structure to invoke various service modules for generating documentation, software development kits, field programmable gate array emulation data structures, and physical design data structures. The controller also facilitates testing using field programmable gate arrays on cloud servers and transmits physical design specifications for manufacturing. Overall, the patent presents a comprehensive approach to integrated circuit design, testing, and manufacturing, leveraging automation and cloud-based resources for efficiency and accuracy in the process.
