Sequence of Covers with Yosys (SCY)
SCY is a tool for creating deep formal traces, by splitting the property to cover into smaller cover properties, which the solver will cover eagerly in sequence.
The cover points themselves are SVA cover properties. Additional data-flow analysis properties and SVA restrict/assume properties can be used to further narrow the search space to certain traces.
