Abstract: Recurrent neural networks (RNNs) can be visualized. For example, a processor can receive vectors indicating values of nodes in a gate of a RNN. The values can result from processing data at the gate during a sequence of time steps. The processor can group the nodes into clusters by applying a clustering method to the values of the nodes. The processor can generate a first graphical element visually indicating how the respective values of the nodes in a cluster changed during the sequence of time steps. The processor can also determine a reference value based on multiple values for multiple nodes in the cluster, and generate a second graphical element visually representing how the respective values of the nodes in the cluster each relate to the reference value. The processor can cause a display to output a graphical user interface having the first graphical element and the second graphical element.

Abstract: A test decompressor and a test method thereof for converting original input data of one single test input into test vectors for testing a circuit under test (CUT) containing scan chains are revealed. The test decompressor includes a test data spreader, a test configuration switch, and a test controller. The test data spreader converts the original input data into a plurality of test data. The test configuration switch receives the original input data and the plurality of test data and transfers these data to scan chains of the CUT. The test controller receives the original input data and outputs a select signal to the test configuration switch for switching current test configuration to another test configuration. The scan chains in the CUT are divided into several scan groups and the scan chains in each scan group share the same test data. Thus the test data volume can be significantly reduced.
