A programmable logic device software test device and test method

The invention provides a programmable logic device software test device and test method. The programmable logic device software test device comprises a test signal excitation generation module, a test control module, a test result acquisition and output module and an analysis module; the programmable logic device software test method comprises the following steps: configuring network parameters of a testing node and a node to be tested, and establishing network connection between the testing node and the node to be tested; creating a test function corresponding to the test case at the test node through a script language, forming a test function sequence, and enabling the test function to send out a calling instruction and generates the test case; and caching and recording the test calling function return value at the test node, and analyzing and outputting a test result according to the test calling function return value. According to the programmable logic device test device and the software test method prov
