In this section, we present projects that used functional prototyping. Prototyping is the most important stage during the creation of any new product. It fails to create a fully working version of the product, which is planned to be released in large quantities. At the same time, you are not limited by the possibilities and performance. You have access to a large number of channels of analog and digital I / O, high performance of a prototype based on FPGA or a processor, the ability to integrate any periphery with any protocol into the prototype. Functional prototyping allows for a very short time to demonstrate to the potential customer a fully working version of the system, which yesterday was an idea.
