Verification platform improves HDL debugging

Aldec Inc. has introduced its mixed-language advanced verification platform that includes enhancements such as visual debugging tools that promise to improve the presentation of simulation results for increased overall verification efficiency. The Riviera-PRO 2013.02 includes a Plot window supporting four different plot types to enable more efficient visualisation of large data sets, as well as the ability to visualise and analyse relations between any objects within a design with no additional programming required, stated the company.

The traditional approach to analysing objects in an HDL design, based on digital waveforms, dataflows, memory and hierarchical viewers, may not be optimal for all applications. For example, in a waveform signal values are represented with respect to time, allowing many parameters to be verified in a digital system. However, when large data sets are used or the correlation between non-linear values must be analysed, engineers will often have too many screens of illegible alphanumeric data to review, losing precious time analysing or investigating alternative methods to represent this data. For this reason, traditional tools might not be the most efficient debugging solution for data-intensive applications such as image processing, digital filtering, industrial control systems, telecommunication systems and certain embedded systems.

Riviera-PRO 2013.02 also includes debugging features such as virtual expressions in the Waveform and conditional expression-based breakpoints. Virtual signal expressions allow observing relations between different signals without having to do any additional coding for debug purposes only. Conditional breakpoints have a wide array of applications; for example, a breakpoint could now be set up on certain instance(s) of a SystemVerilog class.

Riviera-PRO 2013.02 is available.
