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 VHDL-93, the assert statement may have an option label. A concurrent assert statement may be run as a postponed process VHDL -93 allows report to be used on it's own as a sequential statement, giving the same functionality as assert false , except that the default severity is note 2015-02-02 · These are several ways of writing a VHDL assert statement, where condition is of boolean type. assert ; assert severity ; assert report ; assert report severity ; (In VHDL = is the equality comparison operator. It doesn't perform an assignment, like in many software programming languages). The result of each comparison is a boolean (true or false) so can be used with an assert statement. The only part that I think is really wrong is that you must end your if with an end if.

The assert statement's report clause requires a string value. In VHDL-87,this meant that you would need to write and call a function that converts the variable type into a string Hi, I'm to use an assert statement within a function in a VHDL project.
