Case Study: Global Industrial Control Systems Manufacturing Company achieves reliable, preserved post-mortem code coverage in constrained system tests with Vector Software

Global Industrial Control Systems Manufacturing Company - Customer Case Study

Vector Services partnered with a global manufacturer of industrial control systems that builds oil-tanker level‑monitoring devices. The client needed unit testing and code‑coverage collection during system testing but had no dedicated output device; requirements included real‑time capture (no volatile buffering), preservation across resets/power loss, post‑mortem data upload, and no special training for test personnel.

VS proposed adding a 512 kB non‑volatile RAM plug‑in to store coverage data and integrated a VectorCAST/QA module to manage the NV memory with minimal software changes. During testing a floating address line was found, a workaround kept progress moving while the board was reworked, and exhaustive testing followed. The engagement completed in eight days (two ahead of schedule), met all client requirements, preserved coverage across power cycles, and was accepted by the client.
