NEW RESEARCH REPORT: Overcoming the limitations of coding agents in complex software systems
Computational software
Fix customer issues
in hours, not weeks
In the EDA industry, software reliability and correctness are critical. Automotive, semiconductor, and telecommunications clients are especially demanding. Billions of dollars are at risk if chip production is delayed due to defects in EDA tools.

Get your customers back up & running fast
Business challenges
Software crashes and inconsistent results at customer sites lead to uncomfortable conversations. Rigorous IP protection protocols and constrained access to the failing environment make diagnosing issues extremely difficult and time-consuming.
Speculative debugging methodologies, like logging and core dump analysis, often involve slow compile, build, and test cycles, demanding significant effort from both your engineering team and clients, who are working under tight deadlines to meet stringent manufacturing schedules.
Solution
Engineering teams building large-scale complex simulation or computational software use Undo to quickly get a reproducer and accelerate root-cause analysis of customer-reported defects and non-trivial bugs in development and testing.
Trusted by leaders
Trusted by the world’s largest organizations


Undo accelerates time-to-resolution of production issues and minimises customer disruption. The time saved on resolving a single incident paid back our investment.
Fritz Ferstl
SVP Software Development, Altair


We’re able to resolve customer issues from weeks to days now. And customer satisfaction went up.

Head of Central Engineering, Synopsys

Time travel debugging
Fix defects in hours, not weeks
Unlike traditional approaches to debugging, Undo 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.

Key benefits
Deliver a first-class service for your telecoms and semiconductor customers
DIAGNOSE AND FIX BUGS FASTER
Reduce defect resolution time by reducing multiple iterations down to one debug cycle. Record a failure once, then debug the recording.
MINIMIZE BLOCKAGES IN SILICON DESIGN WORKFLOW
Don’t make clients miss their fabrication deadline. Respond fast to incidents in the field.
SAFEGUARD CUSTOMER RELATIONSHIPS
Keep your clients on your side by minimizing delays in their design cycle… and protect your renewal revenue.
Success story

Undo is a member of the Questa Vanguard Program
The Questa Vanguard Program is part of Siemens EDA (formerly Mentor Graphics). It extends Siemens EDA’s breadth of design and verification technologies through partnerships with industry-leading companies.
The Questa Vanguard partners provide verification-related tools and methods, verification IP, conversion services, training and consulting based on Siemens EDA’s industry-leading Questa verification platform. The program was established to bring design and verification engineers world-class product integrations and interoperability to enhance their Questa verification options and build a strong and comprehensive SystemVerilog ecosystem.
