Questa inFact
Intelligent Testbench Automation
Mentor Graphics Questa® inFact is the industry’s most advanced testbench automation solution. It targets as much functionality as traditional constrained random testing, but achieves coverage goals 10X to 100X faster.
This enables engineering teams to complete their functional verification process in less time, and/or to expand their coverage goals, testing functionality that previously fell below the cut line. Questa inFact also generates tests that an engineer might not envision, reaching difficult corner cases that alternative testing techniques typically miss. Using Questa inFact ensures high quality products.

Evolutionary Steps
Revolutionary results are not enough. Advanced technology must fit into existing processes and flows. Questa inFact can be integrated into current verification environments with little to no disruption. It supports UVM (and OVM) methodologies; standard languages such as SystemVerilog, SystemC, C/C++; and even other proprietary testbench languages. And if you are looking for an incremental way to move from a proprietary language to SystemVerilog, Questa inFact can provide a natural bridge, offering the benefits of a standard language while supporting legacy verification IP written in a non-standard language.
Repeatable Results
The number of companies turning to Questa inFact is growing exponentially. The minimum result experienced to date has been 10X faster achievement of target coverage. But many companies have gained 100X or better. Why such dramatic gains in productivity? The nature of constrained random testing lends itself to uncontrollable redundancy. While some repetition can be valuable, Questa inFact enables engineers to control the amount of redundancy desired, while generating the same or a higher quantity of tests.
Examples
One networking company was able to achieve more coverage in 48 CPU hours with Questa inFact than they achieved with constrained random testing in 3175 hours. That’s a gain of 66X. A consumer electronics company was stuck at 60% of their target coverage after 8 weeks of simulation on 6 CPUs. With Questa inFact they were able to achieve 100% of their target coverage in just 36 hours on the same 6 CPUs. That’s a gain of 37X plus 40% more coverage. In both cases, the time needed to integrate Questa inFact was less than a couple of days.
