CHAPTER 2: DESIGN ENTRY

USING ALTERA MEGAFUNCTIONS

50 ■ INTRODUCTION TO QUARTUS II ALTERA CORPORATION

Instantiating Megafunctions in the

Quartus II Software

You can instantiate Altera megafunctions and LPM functions in the

Quartus II software through direct instantiation in the Block Editor, through

instantiation in HDL code (either by instantiating through the port and

parameter definition or by using the MegaWizard Plug-In Manager to

parameterize the megafunction and create a wrapper file), or through

inference.

Table 4. Files Generated by the MegaWizard Plug-In Manager

File Name Description

<output file>.bsf

Symbol for the megafunction used in the Block Editor.

<output file>.cmp

Component Declaration File.

<output file>.inc

AHDL Include File for the module in the megafunction wrapper

file.

<output file>.tdf

Megafunction wrapper file for instantiation in an AHDL design.

<output file>.vhd

Megafunction wrapper file for instantiation in a VHDL design.

<output file>.v

Megafunction wrapper file for instantiation in a Verilog HDL

design.

<output file>_bb.v

Hollow-body or black box declaration of the module in the

megafunction wrapper file used in Verilog HDL designs to

specify port directions when using EDA synthesis tools.

<output file>_inst.tdf

Sample AHDL instantiation of the subdesign in the

megafunction wrapper file.

<output file>_inst.vhd

Sample VHDL instantiation of the entity in the megafunction

wrapper file.

<output file>_inst.v

Sample Verilog HDL instantiation of the module in the

megafunction wrapper file.

Using the Stand-Alone MegaWizard Plug-In Manager

You can use the MegaWizard Plug-In Manager from outside the Quartus II

software by typing the following command at a command prompt:
