Method for improving operation efficiency of circuit design tuning tool

Abstract

The embodiment of the invention provides an adjusting and optimizing method for field programmable gate array circuit design, which comprises the following steps of modifying comprehensive parametersfor a preset number of times, and operating a comprehensive process after each modification to obtain a comprehensive result generated by the comprehensive process; selecting the comprehensive resultwith the minimum logic depth as an intermediate comprehensive result from the comprehensive results generated in each comprehensive process; utilizing the intermediate comprehensive result, modifyingthe operation parameters of other stages except for the comprehensive stage in the tuning process, and operating the processes of other stages to generate an optimization result; if the optimization result reaches the preset optimization condition, ending the tuning process, if the optimization result does not reach and does not exceed the preset judgment frequency, continuing to execute other process parameter modification and operation, and if the optimization result does not reach and exceeds the preset judgment frequency, continuing to execute comprehensive parameter modification and operation; and outputting optimization results. According to the method, a large number of iteration and search steps in an existing tuning method are reduced, the operation complexity of the tuning tool is reduced, and the operation speed of the tuning tool is increased.
