Problems solved by technology

An algorithm library usually includes many algorithms. If the software simulation method provided by the existing technology is used to provide a test stimulus signal for each module separately, and to simulate and verify the modules in the algorithm library one by one, this will inevitably lead to test time and errors. The probability increases sharply. Therefore, how to quickly, efficiently and simply conduct simulation verification and shorten the verification cycle has become an important issue we are facing.

Abstract

The invention provides an FPGA-based algorithm library simulation and verification platform implementation method. The implementation method comprises the following steps: firstly, according to requirements of nuclear power station safety level control system application, implementing all the algorithm blocks through FPGA basically; secondly, producing a simulation excitation vector of each algorithm block; thirdly, if an algorithm block needs to be added, only adding algorithm block content and a corresponding simulation vector on the verification platform, and then modifying a configuration file; and fourthly, carrying out comparison analysis on a simulation result output by a simulation tool and a result generated by a simulator. The implementation method provided by the invention has the advantages that all the algorithm blocks are unified into the same interface, and the algorithm blocks can be automatically called only by modifying the configuration file once the algorithm block or the simulation vector needs to be added, so that the aim of automatic simulation is achieved.
