             abstract = "This article presents the development and implementation of a 
                         structure to assist the systems engineer, considering a process of 
                         choosing a fault mitigation technique for a space system with 
                         electronic integrated circuits of the type COTS FPGA (Commercial 
                         off-the-shelf - Field Programmable Gate Array). Space systems 
                         require space or hard-qualified components, and some applications 
                         also require devices with a high processing rate, low power 
                         consumption, and low cost. The studies surveyed in the available 
                         literature, over a ten-year period, didn't provide sufficient 
                         design details to compare existing mitigation techniques in a 
                         manner consistent with the required parameters. The technique 
                         selected should ensure that the FPGA of the electronic device 
                         works properly with the mission applications and overcomes the 
                         adversities of space, especially the effects of radiation. Due to 
                         factors related to the reduction of costs of these projects and 
                         the possibility of commercial embargo of hard components, the 
                         electronic devices of the type COTS happened to occupy a relevant 
                         space in the engineering of components. COTS FPGAs, although not 
                         manufactured for the radiation environment, cost up to twenty 
                         times less and can absorb, by hardware or software, mitigation 
                         techniques. A space project must meet or exceed all mission 
                         restrictions such as maximum power usage, maximum failure rate, 
                         and minimum required life time. Considering that these 
                         restrictions are different and often conflicting, different types 
                         of solutions are possible. The paper proposes a study of two 
                         frameworks available in the literature, but they present partial 
                         results, watertight and without establishing a standard flowchart. 
                         These frameworks address separately the two types of radiation 
                         effects (TID - Total Ionizing Dose or SEE - Single Event Effects) 
                         and only four mitigation techniques. Just only one of the articles 
                         presents metrics and methodology for the selection process. This 
                         article performs a detailed study on the mentioned frameworks and 
                         proposes measures to build a single framework that overcomes the 
                         disadvantages of the previous two, such as the consideration of a 
                         longer period of research and a greater number of mitigation 
                         techniques, among others. With the implementation of these 
                         measures, the component engineer can only use this tool for the 
                         design of projects in the area of COTS FPGA, with the mitigation 
                         of the radiation effects according to the parameters of the 
                         mission.",
