Thanks to their flexibility and constant performance improvements, Field Programmable Gate Arrays (FPGA) are increasingly being used in the design of modern system solutions. The latest developments with multi-core features and high-performance GBit interfaces are fuelling this trend with lasting effects. From a testing perspective, however, FPGAs offer far more possibilities than simply realising an application. Automatic board test made by FPGA

Automation makes the difference While the use of FPGA-embedded
• How is the IP control implemented?
• Who generates the test data and the guarding vectors? • How is the overall project creation carried out?
instruments appears at first glance to be relatively trivial and straight-forward, more detailed analysis leads to a whole variety of influencing factors and fundamental decisions. The most important of these are: • How is the FPGA-to-UUT topology detected?
• How is diagnosis performed?
• How much time is required for the entire project creation process? • What FPGA design skills and tools are needed? With purely manual implementation, both the IP and the necessary process steps are carried out by the user. This requires
• Who provides the instrument-IP?
• How is JTAG mapping performed?
• How is IP-to-pin configuration carried out?
