You can request CAD (STP) models and/or order mechanical samples if you need additional clarity on the mechanical specifications. The STP file can be used in many popular CAD tools to help understand and model the thermal apparatus, and to see how it fits before committing to prototyping or manufacturing. 3D CAD STEP models for the Versal family are available for download on the AMD website under Device Models. For the UltraScale+ family, they are available upon request.
For further assurance in forming and fitting the device package, and to further inspect and test prototype systems, mechanical samples are available by order.
