Here’s a technical write-up on — their purpose, structure, and typical usage in embedded or automotive calibration contexts. Write-Up: VCP ZDC Files 1. Overview VCP (Vector CANape Platform) and ZDC (ZONEC Interface Description / Data Container) files are used in Vector CANape and Vector ASAP2 Tool-Set environments. A .zdc file is a calibration data container that holds parameter values for ECU calibration, typically generated from an A2L (ASAP2) description file.
