Training This page lists all the online and instructor-led courses currently available. The test bench and FPGA code are run in a simulation environment that models the hardware timing behavior of the FPGA chip and displays all of the input and output signals to the designer for test validation.
Once you have created an FPGA design using HDL and verified it, you need to feed it into a compilation tool that takes the text-based logic and, through several complex steps, synthesizes your HDL down into a configuration file or bitstream that contains information on how the components should be wired together. As part of this multistep manual process, you often are required to specify a mapping of signal names to the pins on the FPGA chip that you are using. Ultimately, the challenge in this design flow is that the expertise required to program in traditional HDLs is not widespread, and as a result, FPGA technology has not been accessible to the vast majority of engineers and scientists.
What is FPGA Programming?
Figure It provides abstraction for the low-level complexity often found when creating and scaling VHDL designs. Without knowledge of the low-level HDL language, you can create test benches to exercise the logic of your design.
In addition, the flexibility of the LabVIEW environment helps more advanced users model the timing and logic of their designs by exporting to cycle-accurate simulators such as Xilinx ISim. LabVIEW FPGA compilation tools automate the compilation process, so you can start the process with a click of a button and receive reports and errors, if any, as compilation stages are completed. It is still important, however, to look inside the FPGA and appreciate how much is actually happening when block diagrams are compiled down to execute in silicon. Understanding resource usage is extremely helpful during development, especially when optimizing for size and speed.

Here is the quick refresher from digital logic class. NI LabVIEW Multiply Function The seemingly simple task of multiplying two numbers together can get extremely resource intensive and complex to implement in digital circuitry. Figure 7.
