Uncommon Signals for ECU/LRU Testers
In making ECU and LRU testers, we come across a lot of common signal types; then there's the rest. While almost every high channel count system has one or two signals that are fairly unique, even the uniques begin to fall into some common buckets after a while. These signals usually represent 10% or less of a given system, though nearly 100% of systems have something more custom than not. It goes without saying that when we find an uncommon signal type - whether it’s on this list or not - we first start by fully assessing the requirements and go from t
Common Signals for ECU/LRU Testers
In making ECU and LRU testers, we come across a lot of common signal types. We estimate that these common signals make up at least 80% of every such system. Here's what we see, where we tend to see it, and how we commonly approach acquiring or generating it.
(These are expressed from the tester's point of view. Our input is your ECU or LRU's output.)
Simulation to Minimize Development Risk
You have a legacy control system that needs to be updated to new hardware and software while maintaining the same behavior as the old system. Building a system that simulates the environment of the legacy system can help. For example: if you are creating a new control system for a rocket launch facility, you would create a system that simulates the rocket and the launch facility.
