Speed and Area Optimization

Improvements through resource sharing, streaming, pipelining, RAM mapping, loop optimization

For your target hardware, generate HDL code from a Simulink® model that meets timing and area requirements by using speed and area optimizations. Area optimizations reduce resource usage of your design. Speed optimizations improve the timing of your design on the target FPGA so that your design runs at higher frequencies by optimizing the critical path. To learn more about each type of optimization in HDL Coder™, see Speed and Area Optimizations in HDL Coder.
