Chapter 4: Importing HDL Modules

Black Box Examples

Importing a Xilinx Core Generator Module

This topic describes two different ways of importing Xilinx CORE Generator™ modules,

as black boxes, into System Generator. The first example shows how to import blocks

which satisfy Black Box HDL Requirements and Restrictions. The second example shows

Black Box Tutorial Example 1:

Importing a Core Generator

Module that Satisfies Black Box

HDL Requirements

Describes an approach that uses the System Generator

Black Box Configuration Wizard.

Black Box Tutorial Example 2:

Importing a Core Generator

Module that Needs a VHDL

Wrapper to Satisfy Black Box

HDL Requirements

Describes an approach that requires that you to

provide a VHDL core wrapper. Simulation issues are

also addressed.

Black Box Tutorial Example 3:

Importing a VHDL Module

Describes how to use the Black Box block to import

VHDL into a System Generator design and how to use

ModelSim to co-simulate.

Black Box Tutorial Example 4:

Importing a Verilog Module

Demonstrates how Verilog black boxes can be used in

System Generator and co-simulated using ModelSim.

Black Box Tutorial Example 5:

Dynamic Black Boxes

Demonstrates dynamic black boxes using a transpose

FIR filter black box that dynamically adjusts to

changes in the widths of its inputs.

Black Box Tutorial Example 6:

Simulating Several Black Boxes

Simultaneously

Demonstrates how several System Generator Black

Box Blocks can be co-simulated simultaneously, using

only one ModelSim license while doing so.

Black Box Tutorial Exercise 7:

Advanced Black Box Example

Using ModelSim

Describes how to design a Black Box block with a

dynamic port interface and how to configure a black

box using mask parameters. Also, describes how to

assign generic values based on input port data types

and how to save black box blocks in Simulink libraries

for later reuse. How to specify custom scripts for

ModelSim HDL co-simulation is also covered.

Black Box Tutorial Example 8:

Importing, Simulating, and

Exporting an Encrypted VHDL

File

Describes how to import an encrypted VHDL file into

a Black Box, simulate the design, then export the

encrypted VHDL file separately from the rest of the

design netlist.

Black Box Tutorial Exercise 9:

Prompting a User for Parameters

in a Simulink Model and Passing

Them to a Black Box

Describes how to access generics/parameters from

the masked counter and pass them onto the black box

to override the default local parameters in the VHDL

file.
