Model Design and Compatibility Guidelines
Recommended guidelines for designing Simulink models, MATLAB Function blocks, and
Stateflow charts to ensure compatibility and effective HDL code generation
The HDL modeling guidelines are a set of recommended guidelines for creating Simulink® models, MATLAB Function blocks, and Stateflow® charts for code generation with HDL Coder™. The model design and compatibility guidelines consist of guidelines for basic block usage, clock and reset signals, buses and vectors, and subsystem and hierarchical designing.
