VHDL Testbenches · A common way to write a self-checking testbench is with assert statements. · Asserts are generally followed by a report statement, which prints

To my knowledge ISim doesn't support VHDL-2008; so extern signal is not in consideration.

VHDL Synthesizer, see Appendix A, “Quick Reference.” • For a list of exceptions and constraints on the VHDL Synthesizer's support of VHDL, see Appendix B, “Limitations.” This chapter shows you the structure of a VHDL design, and then describes the primary building blocks of VHDL used to describe typical circuits for synthesis: In our example the entity is associated to only one architecture named arc that contains only one VHDL statement: assert false report "Hello world!" severity note; The statement will be executed at the beginning of the simulation and print the Hello world! message on the standard output.
