We present FPGA-implementation techniques to efficiently validate application readiness of a product for analog/mixed-signal (AMS) applications. Further, we show how proposed techniques are used on the example of a power conversion application and compare results including area utilization, timing impact and scalability at increased application complexity with state-of-the-art approaches. The open source synthesizable model generator for mixed-signal blocks \textbf{msdsl} is extended to support reconfigurable variables within a model description. Further, the control API of the open source FPGA prototyping automation \textbf{anasymod} is enhanced to allow updating these variable values on FPGA between test case execution. The end-result is a unique framework for application scenario driven product validation that leverages benchmark AMS system simulation throughput on FPGA and enables fast system property sweeping across modeling abstractions at a low overhead via a seamless integration into the existing tools.
