The complexity of automotive simulation licensing
As autonomous driving and vehicle dynamics validation become more complex, managing IPGLock—the proprietary licensing system for IPG Automotive—presents unique challenges. Your engineering teams rely on CarMaker, TruckMaker, and Formula CarMaker to bridge the gap between virtual design and physical reality.
The test-bench vs. engineer conflict
A major friction point in automotive R&D occurs when automated Hardware-in-the-Loop (HIL) test benches and human engineers compete for the same license pool. Often, automated nightly tests or continuous validation loops “lock up” licenses, preventing engineers from launching interactive sessions during business hours. Without real-time IPGLock monitoring, you cannot see if a license is held by a high-priority simulation or a stalled test rig.
The “zombie” validation session
Virtual testing tools are high-value assets that cannot afford to sit idle. Budget leaks occur when CarMaker sessions are left open on workstations over the weekend or when a simulation crashes but the IPGLock daemon fails to release the seat. Every unused minute is a delay in your validation matrix.
Quick summary: OpenLM for IPGLock
OpenLM empowers automotive R&D teams to move from resource contention to orchestrated access.
- Automated IPGLock usage tracking: Monitor check-outs and check-ins across your entire simulation stack in real time.
- Test-bench observability: Distinguish between automated HIL consumption and interactive user activity.
- Identify stalled simulations: Detect when a test rig has crashed but is still holding a license “hostage.”
- Idle session cleanup: Automatically flag and recover licenses from CarMaker instances that are open but inactive.
- Bottleneck identification: Record denial events to prove exactly when and why validation teams are blocked.
Comprehensive solution framework
OpenLM provides a three-layered approach to help you manage IPGLock licenses efficiently across the vehicle development lifecycle.
The visibility layer
Gain a unified view of your IPG Automotive entitlements. See exactly which engineer or HIL system is holding a license. OpenLM interfaces with the IPGLock daemon to provide a live “state of the union” for your simulation assets.
The automation layer
Move beyond manual license monitoring. OpenLM’s automation engine identifies idle sessions and alerts administrators. This allows you to reclaim licenses with workstation-level precision, ensuring that “crunch periods” are supported by maximum license availability.
The intelligence layer
Leverage historical data to right-size your next IPG Automotive renewal. By analyzing usage profiling—tracking session duration and frequency—you can understand your peak testing windows and avoid over-purchasing niche feature licenses.
Technical details: the OpenLM IPGLock integration
OpenLM uses a secure, API and log-based approach to capture every detail of your IPG Automotive environment.
Seamless connectivity and monitoring
- Full IPG suite support: Monitor licenses for CarMaker, TruckMaker, and all associated toolboxes.
- Broker-led precision: The OpenLM Broker (v25.x or higher) connects via the Telnet protocol to the IPGLock server (default port 11010) for real-time data inquiry.
- License file parsing: OpenLM reads the standard IPG license files (typically named Licenses in the etc directory) to track feature-level entitlements.
- High-resolution data: Collect usage statistics with 1-second resolution, providing the granularity needed for HIL auditing.
Advanced analytics
- Denial reporting: Log every time a user is turned away. Use this data to justify hardware or software expansion.
- System ID (sysID) tracking: Associate license usage with specific hardware fingerprints to manage node-locked and floating pools in one view.
Strategic ROI and business value
Organizations leveraging OpenLM for IPG Automotive typically see a $15\text{–}20\%$ increase in simulation throughput.
- Procurement support: Use “actual activity” data to negotiate your next Enterprise agreement instead of relying on headcount or test-bench estimates.
- Reduced time-to-market: By eliminating license bottlenecks, your validation teams can maintain a continuous testing cycle without manual intervention.
- Global asset management: Centralize IPGLock management alongside other automotive tools (like dSPACE, Vector, or MATLAB/Simulink) for a single source of truth.
