Why is vhdl concurrent

Notes The behavior of the so called selected signal assignment is similar to the case statement. Modeling of multiplexers. Notes All concurrent statements describe the functionality of multiplexer structures. Consequently, the unconditional else path is necessary in conditional signal assignments. Concurrent statements General Issues. Data Types. Process Execution. Extended Data Types. If you keep in mind this concept, it will be clear that VHDL code is concurrent and not sequential as classical programming languages.

The order of execution is defined only by events occurring on the signals that the assignments are sensitive to.

It is clear that the output cannot be different. Every time you use VHDL you must remember that you are implementing hardware logic so you must.
