Mixed-signal modeling using Simulink based-C

This paper presents a top-down mixed-signal modeling approach that relies on Simulink converted-C modeling. This modeling flow is divided into four fundamental operations: 1) Build the behavioral model using Simulink. 2) Generate the portable stand-alone C code using RTW. 3) Use FLI to link the generated C code with HDL. 4) Write HDL wrappers. The resulting discrete-time C-based HDL model can seamlessly integrate with the digital and mixed-signal simulation environments without any special requirements from the simulator. With this approach we can truly achieve chip level or system level mixed-signal verification and analog vector generation.
