New features and changes introduced in this version are

• Sign Block Supported for HDL Code Generation

• Link for Cadence Incisive HDL Cosimulation Block Supported

• GUI Support for Generation of EDA Tool Scripts

• Embedded MATLAB Function Block Supported for HDL Code Generation

• Stateflow HDL Code Generation Updates

Sign Block Supported for HDL Code Generation

The Sign block (Simulink/Math Operations/Sign) is now supported for HDL code generation.

Link for Cadence Incisive HDL Cosimulation Block Supported

The coder now supports HDL code generation for the Link for Cadence^® Incisive^® HDL Cosimulation Block. You can use the HDL Cosimulation block with the coder to generate an interface to your manually written or legacy HDL code. When an HDL Cosimulation block is included in a model, the coder generates a VHDL or Verilog interface, depending on the selected target language. See Code Generation for HDL Cosimulation Blocks for details.

GUI Support for Generation of EDA Tool Scripts

The new EDA Tool Scripts pane of the GUI (shown in the following figure) lets you set all options that control generation of script files for third-party electronic design automation (EDA) tools. In previous releases, script generation options were available only through makehdl and makehdltb properties.

The list on the left of the EDA Tool Scripts pane lets you select from the following categories of options:

• Compilation script: Options related to customizing scripts for compilation of generated VHDL or Verilog code.

• Simulation script: Options related to customizing scripts for HDL simulators.

• Synthesis script: Options related to customizing scripts for synthesis tools.

See Generating Scripts for HDL Simulators and Synthesis Tools for detailed information on the EDA Tool Scripts options and on script generation in general.

Embedded MATLAB Function Block Supported for HDL Code Generation

The coder now supports synthesizable HDL code generation from the Embedded MATLAB Function block. See Generating HDL Code with the Embedded MATLAB Function Block for detailed information.

Stateflow HDL Code Generation Updates

This section describes some limitations on the use of Stateflow charts in HDL code generation have been removed in the current release. These are:

Restriction on Reading from Output Ports Removed

In the previous release, reading from output ports was disallowed. This restriction has been relaxed. You can now read from output ports if outputs are registered. (Outputs are registered if the Initialize Outputs Every Time Chart Wakes Up option is deselected.)

Stateflow Charts Fully Support Fixed Point Data Type

In the previous release, fixed-point data type support for Stateflow HDL code generation was limited to fixed point without scaling. This limitation has been removed. You can now use fixed-point data types without restriction in Stateflow charts intended for HDL code generation.
