WebThe immediate assertion will pass if the expression holds true at the time when the statement is executed, and will fail if the expression evaluates to be false (X, Z or 0). These assertions are intended for use in simulation and is not suitable for formal verification. It can be used in both RTL code and testbench to flag errors in simulations.
