If a property of the design that is being checked for by an assertion does not behave in the expected way, the assertion fails. For example, assume the design requests for … See more Immediate assertions are executed like a statement in a procedural block and follow simulation event semantics. These are used to verify an … See more An assertion is nothing but a more concise representation of a functional checker. The functionality represented by an assertion can also be written as a SystemVerilog task or checker that involves more line of code. Some … See more Concurrent assertions are based on clock semantics and use sampled values of their expressions.
