Generating HDL Code from Simulink

Day 1 of 2

Preparing Simulink Models for HDL Code Generation

Objective: Prepare a Simulink model for HDL code generation. Generate HDL code and testbench for simple models requiring no optimization.

• Preparing Simulink models for HDL code generation
• Generating HDL code
• Generating a test bench
• Verifying generated HDL code with an HDL simulator

Fixed-Point Precision Control

Objective: Establish correspondence between generated HDL code and specific Simulink blocks in the model. Use Fixed-Point Tool to finalize fixed point architecture of the model.

• Fixed-point scaling and inheritance
• Fixed-Point Designer workflow
• Fixed-Point Tool
• Command-line interface

Generating HDL Code for Multirate Models

Objective: Generate HDL code for multirate designs.

• Preparing a multirate model for generating HDL code
• Generating HDL code with single or multiple clock pins
• Understanding and applying techniques used for clock domain crossing

Optimizing Generated HDL Code

Objective: Use pipelines to meet design timing requirements. Use specific hardware implementations and share resources for area optimization.

• Generating HDL code with the HDL Workflow Advisor
• Meeting timing requirements via pipelining
• Choosing specific hardware implementations for compatible Simulink blocks
• Sharing FPGA/ASIC resources in subsystems
• Verifying that the optimized HDL code is bit-true cycle-accurate
• Mapping Simulink blocks to dedicated hardware resources on FPGA

Using Native Floating Point

Objective: Implement floating point values and operations in your HDL code.

• Why and when to use native floating point
• Target-independent HDL code generation with HDL Coder
• Fixed-point vs. floating point comparison
• Optimization of floating point implementations

Interfacing External HDL Code with Generated HDL

Objective: Incorporate hand-written HDL code and/or vendor party IP in your design.

• Interfacing external HDL code

Verifying HDL Code with Cosimulation

Objective: Verify your HDL code using an HDL simulator in the Simulink model.

• Verifying HDL code generated with HDL Coder
• Comparing manually written HDL code with a "golden model"
• Incorporating HDL code into Simulink for simulation
