The article discusses the use of the Python programming language to implement elements of the UVM methodology. The methodology is designed to work in FPGA CAD and uses the System Verilog language. The possibility of replacing the System Verilog language used in UVM with a general-purpose programming language is considered, which allows accelerating the process of modeling digital signal processing systems. The article proposes a modified class hierarchy that reproduces the functionality of the agent component from UVM. An example of generating periodic signals for testing precision phase measurementsystems is considered. A model of a software application in Python is developed and a class hierarchy is proposed that uses the property of multiple inheritance to transfer global model parameters within this hierarchy.

This paper explores various design strategies for low-voltage, high current DC-DC converters, in order to optimize efficiency, volume, and mass, while keeping the project as simple and cost efficient as possible by using only on-the-shelf components, including inductor and heatsinks. The impact of topologies on both efficiency and compactness is studied for a specific aeronautical application. A 2kW 3-level FCML module has been developed for a 100V to 28V DC-DC step-down. It relies on pairs of paralleled EPC2022 GaN transistors to significantly increase converter power density. Two routing strategies to reduce parasitic switching loops are compared using computer simulations, with experimental verification. First experimental results on a prototype show an efficiency up to 98.4% for a specific power of 12.5kW/L.
