As I stated in an earlier blog post, I’m planning to discuss one of five industry trends per blog entry over the next few weeks. My 3rd trend is:
Growing Popularity of FPGA-Enabled Instrumentation
Another area experiencing rapid expansion in the test industry is the increase in system-level tools for field-programmable gate arrays (FPGAs). FPGAs are powerful because they are inherently parallel, deterministic, and reliable and can be defined and reconfigured in software. While FPGAs are used inside many embedded designs, and even standalone instruments, users are not typically given access to reprogram them. More manufacturers are beginning to include open FPGAs on modular instruments and are giving test engineers the means in software to reprogram them according to their requirements. With this capability, test engineers can embed a custom algorithm into the device to perform in-line processing inside the FPGA or emulate part of the system that requires a real-time response. Historically, most test engineers do not have expertise to program FPGAs because they familiarity with hardware description languages like Verilog or VHDL which use low-level syntax to describe hardware behavior. New system-level tools are emerging that provide test engineers with the ability to rapidly configure FPGAs without writing low-level HDL code. LabVIEW, for example, can target onboard FPGAs and synthesize the necessary hardware directly from a graphical LabVIEW program, dramatically reducing the complexity of the code development. I’ve been amazed at the things our customers, who are often domain exprerts, but not experts in hardware design, have been able to accomplish with LabVIEW FPGA. Examples include testing RFID devices performing bit-error-rate testing (BERT) of military communication protocols.
