Fix software defects faster and unblock your customers' pipeline

In the EDA industry, software reliability and correctness are key requirements. Automotive, semiconductor and telecommunication clients are particularly demanding. Many billions of dollars are at stake if chips are delayed by defects in EDA tooling.

Business challenges

Software crashes and inconsistent results from EDA tools bring real challenges for your engineers. Rigorous IP protection protocols and constrained access to the failing environment make it extremely difficult to diagnose issues.

Traditional debugging methodologies are speculative and time-consuming. Logging and core dump analysis usually require slow compile / build / test cycles demanding substantial efforts from both your engineering team and your clients.

Meanwhile, your clients are in a hurry to meet stringent manufacturing deadlines.


LiveRecorder is widely used across the largest EDA tools vendors to resolve defects faster – both in production and in development/test.

Simulation and verification engineering teams use LiveRecorder to quickly get a reproducer and accelerate root-cause analysis.

Fix defects in hours (not weeks) with LiveRecorder

Unlike traditional approaches to debugging, LiveRecorder enables engineers to record the execution of a software program – capturing bugs in the act.

The recording allows engineers to observe exactly what the program did, and why.

By stepping forward and backward in the recording file, engineers can quickly diagnose the root cause of issues.

This workflow significantly improves engineering productivity, since no time is wasted trying to reproduce failures.
