Wireless RF receivers are used in a range of applications, including wireless security systems, industrial monitoring, meter reading, and home automation. In the past, semiconductor suppliers primarily built these receivers using analog designs. Today, suppliers are transitioning to digital and mixed-signal designs to reduce power consumption and ease integration with other components.
Engineers at Semtech are expanding their use of MathWorks tools for Model-Based Design to transition to a digital platform. For years, the engineers modeled and generated HDL code for filters with MATLAB® and Filter Design HDL Coder™. On their most recent project, they used Simulink® and HDL Coder™ to generate VHDL® for the entire design.
“There is no advantage to writing VHDL by hand,” says Frantz Prianon, IC design engineer at Semtech. “With Simulink and HDL Coder, we have one model of the system. We simulate it, so we know it works. And we generate code from it, so we can use one model until the end of the project. This is an important capability, because we are sure that what we have implemented matches the design and that the design meets specifications.”
