Verilog code for 2:1 MUX using data flow modeling. To start with this, first, you need to declare the module. There’s no need for data- type declaration in this modeling. module m21(Y, D0, D1, S); output Y; input D0, D1, S; Now since this the dataflow style, one is supposed to use assign statements. Fig. 3. Bitmask-based test data compression. Once the input test data is considered, next task would be to divide them into scan chains of predetermined length. Lets assume that the test data consists of N test patterns. Divide the scan elements into m scan chains in the best balanced manner possible.The report discusses the how the project was executed and how we designed the control unit and datapath.
