Using the Black Box Methodology
You can use the MegaWizard Plug-In Manager to generate Verilog HDL or
VHDL wrapper files for megafunctions. For Verilog HDL designs, the
MegaWizard Plug-In Manager also generates a Verilog Design File that
contains a hollow-body declaration of the module, used to specify port
directions.
The Verilog HDL or VHDL wrapper file contains the ports and parameters
for the megafunction, which you can use to instantiate the megafunction in
the top-level design file as well as a sample instantiation file and then direct
the EDA tool to treat the megafunction as a black box during synthesis.
The following steps describe the basic flow for using the MegaWizard
Plug-In Manager to create a black box for an Altera megafunction or LPM
function in EDA design entry and synthesis tools:
1.
2.
3.
Create and parameterize the megafunction or LPM function using the
MegaWizard Plug-In Manager .
Instantiate the function in the EDA synthesis tool with the black box file
or component declaration (along with the sample instantiation file)
generated by the MegaWizard Plug-In Manager .
Perform synthesis and optimization of the design in the EDA synthesis
tool. The EDA synthesis tool treats the megafunction as a black box
during synthesis.
Instantiation by Inference
EDA synthesis tools automatically recognize certain types of HDL code and
infer the appropriate megafunction.You can directly instantiate memory
blocks (RAM and ROM), DSP blocks, shift registers, and some arithmetic
components in Verilog HDL or VHDL code. The EDA tool then maps the
logic to the appropriate Altera megafunction during synthesis.
Using the Clear Box Methodology
In the black box flow, an EDA synthesis tool treats Altera megafunctions and
LPM functions as black boxes. As a result, the EDA synthesis tool cannot
fully synthesize and optimize designs with Altera megafunctions, because
the tool does not have a full model or timing information for the function.
