![]() ![]() The dataflow modeling represents the flow of the data. ![]() RTL schematic Gate-level modeling Data flow modeling It is clear that the gate-level modeling will give the exact involved hardware in the circuit of the system. Notice the resemblance between the logic circuit of 4:1 MUX and this picture. This hardware schematic is the RTL design of the circuit. Similarly for the rest of the two gates and (T1, a, s0bar, s1bar), (T2, b, s0bar, s1), (T3, c, s0, s1bar), (T4, d, s0, s1) Here s0bar and s1bar are the output to the first and second NOT gate respectively and s0 and s1 are the input to the first and second NOT gate. Here’s how you would do it for the two NOT gates. Separate the list for a particular gate by appropriate brackets, if there exists more than one same logic gate. Time for us to write for the logic gates. Example: signals that are emerging from the NOT gate. Note that the intermediate signals are those that are not involved in the port list. The intermediate signals are declared as wires. ![]()
