Chapter 4: Using MegaCore Functions
Updating MegaCore Function Variation Blocks
Updating MegaCore Function Variation Blocks
Although a DSP Builder design using MegaCore function blocks from the MegaCore
Functions library can be translated by Signal Compiler into a VHDL or Verilog HDL
model, a MegaCore function variation block always uses an intermediate VHDL file
to record parameters.
These blocks may revert to their unconfigured appearance if the VHDL file that
describes the function variation is available but the simulation database ( .simdb) file
is not.
Update a block if you change the version of the MegaCore function you are using. In
these cases, you can update the MegaCore function variation blocks in your design
using the alt_dspbuilder_refresh_megacore command. This command recreates the
simulation files based on the VHDL file for each MegaCore function block in the
current Simulink model.

A Quartus II license must be available on the machine for the command to execute
without errors.
Design Flow Using MegaCore Functions
Using MegaCore functions in the MATLAB or Simulink environment involves the
following steps:
1. Add the MegaCore function to the Simulink model and give the block a unique
name.
2. Parameterize the MegaCore function variation.
3. Generate the MegaCore function variation.
4. Connect your MegaCore function variation to the other blocks in your model.
5. Simulate the MegaCore function variation in your model.
f Refer to the appropriate MegaCore function user guide for information about the
design flow used for each MegaCore function.
Adding the MegaCore Function in the Simulink Model
Add a MegaCore function to a Simulink model by dragging a copy of the block from
the Simulink Library Browser to your design workspace like any other Simulink
block.
The default name of a MegaCore function block includes its version number. If you
add more than one copy of a block in the same model, this number is automatically
incremented to make the name unique. The correct version number still shows on the
body of the block. Altera recommends that you rename all blocks representing
MegaCore functions with a name describing their use in your design. Using unique
block names ensures that all the generated entities for the same MegaCore function in
a hierarchical design also have unique names.
After adding the block and before parameterization, save your model file.
