Coverage Acceleration

Questa One Sim CX

Questa One Sim CX offers a coverage-driven simulation approach to accelerate coverage closure of hard to hit coverage goals. Using a wide range of capabilities, it can help with coverage challenges from design creation stage, through simulation bring-up and all the way to last mile coverage closure

Why Questa One Sim CX?

Achieving coverage closure in modern SystemVerilog UVM environments is costly and time-consuming. Questa One Sim CX is a coverage acceleration capability that uses innovative technologies to help users to start their coverage early, ramp up faster and close coverage more predictably.

Start early and find bugs faster

Even before coverage models are written, Questa One Sim CX can help generate an exhaustive set of non-redundant stimuli within spatial constraints, to stress test designs thoroughly and efficiently.

Ramp faster with reachability analysis

Questa One Sim CX can identify functional coverage bins that are not reachable due to user constraints. This helps the user quickly find over-constrained stimuli that exacerbate the coverage closure process.

Close predictably with coverage acceleration

Utilizing advanced algorithms, Questa One Sim CX can accelerate coverage closure by targeting remaining coverage holes based on the relationship inferred between the random variables and the user coverage model.

Tackling the coverage closure challenge

The final stretch of coverage closure is the steepest part of the verification journey. Traditional approaches suggest adding more tests, more compute power and more brute force to achieve the target coverage metrics. Questa One Sim CX provides a smarter and a more efficient way to reach your coverage goals. It analyzes your current coverage landscape and generates optimal stimulus to reach your coverage goals.
