A parameter list is used with some attributes. Generally: T represents any type, A represents any array or constrained array type, S represents any signal and E represents a named entity. via assert,report,severity blocks.

Second, these assertion crashes only happen while you're debugging. In fact, because calls to assert() are ignored in release builds of your app, you can do

Asserts are used to perform validations in the test scripts.

return std_logic_vector is begin assert FALSE report "Test assert." severity 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 VHDL Testbench Development ➺Testbench = VHDL entity that applies stimuli (drives the inputs) to ASSERT condition -- must hold during entire simulation. Since testbenches are used for simulation purpose only (not for synthesis), therefore full range of VHDL constructs can be used e.g. keywords 'assert', 'report' [ label: ] assert boolean_condition [ report string ] [ severity name ] ; assert a=(b or c); assert j
[ label: ] assert condition [ report string_expression ] [ severity expression ]; Description: The assertion statement has three optional fields and usually all three are used. The condition specified in an assertion statement must evaluate to a Boolean value (true or false). If it is false, it is said that an assertion violation occurred.

The specified text contains the report string associated with the assertion.
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!
