Overview

Questa AutoCheck

Find bugs early in the design! Questa AutoCheck automatically generates properties to support an ever-growing variety of static and dynamic checks such as dead code analysis, finite state machine deadlock, combinatorial loops, and liveness; covering common design errors and unimagined corner cases.

Key features

The designers’ verification dilemma

SVA and PSL are time-consuming. The Questa AutoCheck app makes it easy to triage bugs that would otherwise require a lot of time and effort to eliminate, such as state-machine deadlock and livelock, arithmetic overflow, and out-of-range memory indexing.

Easy-to-use

Push-button bug hunting

  • No knowledge of formal or ABV is required!
  • Automatic assertion creation eliminates the need to write assertions
  • Leverages the common Questa Visualizer Debug Environment

Improve design quality

Finds bugs early in the design cycle

  • Start verifying as soon as RTL code is written or changed
  • No testbench or assertions are necessary!
  • Explores sequential design behavior to find corner-case bugs that will be missed by lint
  • Find common functional design issues in registers, FSMs, buses, and memories
  • High signal-to-noise ratio–less likely to miss “real” issues in the noise

Automatic detection of common RTL coding errors

Finite state machine deadlock

Questa AutoCheck is a fully-automatic formal bug hunting app that finds bugs due to common RTL coding errors. AutoCheck makes it possible to eliminate a wide range of bugs with low effort. Neither a testbench nor assertions are required to be available, making it possible to start formally verifying designs as soon as the RTL code is written.
