Using Questa inFact technology ensures high quality
Revolutionary results are insufficient if new technology doesn’t fit into existing processes and flows. Questa inFact easily integrates into current verification environments, reusing existing classes, constraints, and covergroups to allow teams to continue benefiting from existing descriptions.
Integration
Evolutionary Steps
Revolutionary results are not enough. Advanced technology must fit into existing processes and flows. Questa inFact integrates into current verification environments with little to no disruption. It supports the UVM, standard languages such as SystemVerilog, SystemC, C/C++, and even C tests for embedded processors.
Repeatable Results
Achieve coverage goals 10X to 100X faster
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.
Customer Examples
Real-World Results
With Questa inFact, one company achieved more coverage in 48 CPU hours than they had with constrained random testing in 3175 hours, 66x gain. Another was stuck at 60% of target coverage after 8 weeks of simulation on 6 CPUs. They achieved 100% target coverage in just 36 hours on the same 6 CPUs.
