1. Find the minimum-cost SOP expression for the function F1 = fm(0,2,4,6,8,10,14) + d(1,5,11,15) using K-Maps. Model the function F1 using (a) Dataflow Modeling, (b) Behavioral Modeling, and (c) Structural Modeling. Use Modelsim and a VHDL test bench to simulate all the three models.
2. Model and simulate a 4-to-1 multiplexer using (a) Dataflow Modeling, (b) Behavioral Modeling, and (c) Structural Modeling. Use Modelsim and a VHDL test bench to simulate all the three models for a 4-to-1 multiplexer. Use basic gates for structural modeling.
