SVA assume/assertions for continuous data input

WebAssertions are primarily used to validate the behavior of a design. An assertion is a check embedded in design or bound to a design unit during the simulation. Warnings or errors are generated on the failure of a specific condition or sequence of events. Assertions are used to, Check the occurrence of a specific condition or sequence of events. Webexplanations about getting around (or working with) SVA, or using other alternatives (see my paper SVA Alternative for Complex Assertionsii). It turns out that many of these solutions require a different point of view in approaching the assertions, and often require supporting logic. All code along with simple testbenches is provided.

WebTo get started, one simply types or pastes an assertion into Zazz’s SVA text box. From our APB example, we might start with a simple assertion that outlines the APB protocol. The assertion triggers on the start of an APB transfer (PSEL active) and then checks that PENABLE is high the 2nd cycle and then terminates when PREADY is asserted. WebAssertion language provides a way to express the properties and constraints for property based formal verification environment. Current assertion languages such as SVA and PSL offer a great set of constructs that enables one to write assertions in number of ways.
