The electronics test engineer is constantly challenged by a myriad of digital interfaces. Military, Space, Communications, and Automotive electronics all utilize both industry standard and custom digital interfaces. Many of these interfaces are supported with test instrumentation that is dedicated to a specific interface or alternatively, a cycle-based, general purpose digital I/O instrument may be...
AXIe is a new standard for test and measurement. It provides an open, high-performance platform for instrument module. In order to reduce the complexity of developing AXIe instrument module, the authors designed an interface component by taking a FPGA as core controller. The component implements an AXIe interface and two High Speed Mezzanine Card (HSMC) interfaces which are used to connect different...
AXIe is the latest auto-test system architecture. Based on the in-depth analysis of AXIe specification, this paper has implemented an AXIe relay module by taking FPGA as the core controller and building Qsys system on chip. It serves as an instrument module in the system and the relays on board can be controlled correctly by the host through AXIe interface. The module has been proved to operate normally...
We consider optimization techniques for a problem that requires a valid scheduling and allocation of tasks on Field Programmable Gate Arrays (FPGAs). A concrete application on a scientific space instrument arises in the context of ESA's Solar Orbiter mission; making use of dynamic reconfiguration allows a good and flexible use of resources, but the resulting packing and scheduling problems in the...
This paper studies a new approach for board-level test based on synthesizable embedded instruments implementted on FPGA. This very recent methodology utilizes programmable logic devices (FPGA) that are usually available on modern PCBs to a large extent. The purpose of an embedded instrument is to carry out a vast portion of test application related procedures, perform measurement and configuration...
The main purpose of this paper is to refine the benefits of the FPGA-based synthetic instrumentation concept (see Section 1) proposed by us earlier [1] as well as to provide some new experimental data based on real industrial designs to show the efficiency of our methodology (see Section 2).
In this demo, we showcase recent tools for deploying dataflow models on FPGA targets. These tools are part of the LabVIEW product family from National Instruments. Through practical application examples, we highlight the design, analysis, implementation, and IP integration capabilities of these tools.
Recent trends show an increasing number of weblabs, implemented at universities and schools, supporting practical training in technical courses and providing the ability to remotely conduct experiments. However, their implementation is typically based on individual architectures, unable of being reconfigured with different instruments/modules usually required by every experiment. In this paper, we...
ISAAC is a highly capable, highly reusable, modular, and integrated FPGA-based common instrument control and computing platform for a wide range of instrument needs as defined in the Earth Science National Research Council (NRC) Decadal Survey Report. This paper presents its motivation, technical approach, and the infrastructure elements. It also describes the first prototype, ISAAC I, and its application...
A hardware structure of LXI bus instruments based on Nios II core is presented in this paper. By the translation of muC/OS II operating system and the lwIP stack on the Nios II core, the TCP and IP protocols are realized. The Web server and the Ethernet protocols are also realized by the programming interface supplied by the lwIP stack. Finally the paper tests the network protocols on the LXI module...
