Questa Codelink

Questa Codelink works much in the same way as the latest generation of digital video recording (DVR) devices. During functional simulation, Questa Codelink's advanced tracing technology automatically captures and compresses all of the important activity inside the design's processors, enabling the verification engineer to "playback" the simulation with features such as fast forward, rewind, pause, single step, and even the equivalent of zoom and pan.

Everything is fully synchronized and easily viewed, including logic simulation waveforms, processor states, source code, internal memory, registers, stacks, and output. Questa Codelink then presents only the important information needed to quickly debug software driven tests, much in the same way that a DVR quickly skips over unwanted commercials, allows you to rewind and replay interesting scenes you missed the first time, and even allows you to zoom in and run in slow-motion or single-step mode to get a really close look.

As a result, companies using Questa Codelink have been able to reduce their system level debugging time from months to days. Complex simulation failures that used to require extensive analysis of multiple files and databases, can now be diagnosed within one robust multi-viewing debugging environment called Questa Codelink.
