16. Nvdx lib base

The nvdx_lib_base is a base scenario for the NVIDIA Base Shadow Scenario Library, which contains common parameters, coverage, and KPIs. This scenario is inherited by all the scenarios. The metrics can be identified by the prefix ftlx_.

Scenario location: $FTX/env/nvidia/nvdx_lib/ftlx/base
