Below diagram shows the steps involved in the creation of an SVA checker,
The functionality is represented by the combination of multiple logical events. These events could be simple Boolean expressions.
Boolean expression events that evaluate over a period of time involving single/multiple clock cycles. SVA provides a keyword to represent these events called “sequence.”
sequence name_of_sequence; …… endsequence
A number of sequences can be combined logically or sequentially to create more complex sequences. SVA provides a keyword to represent these complex sequential behaviors called “property”.
property name_of_property; test expression or complex sequence expressions endproperty
The property is the one that is verified during a simulation. It has to be asserted to take effect during a simulation. SVA provides a keyword called “assert” to check the property.
assertion_ name: assert_property( property_name );
