Inversion. Data transformation analysis. XOR. XOR analyzer
In this webinar, the Inversion and the XOR transformations will be discussed. We will show how to check with the VNR if the Inversion or the XOR transformation was used by a NAND controller, and then how to eliminate it with the Data transformation analysis or with the XOR analyzer tool.
