The black box can import VHDL and Verilog modules.
SysgenBlockDescriptor provides a method,
setTopLevelLanguage, that tells the black box what type of module
you are importing. This method should be invoked once in the configuration M-function.
The following code shows how to select between the VHDL and Verilog languages.
VHDL Module:
this_block.setTopLevelLanguage('VHDL');
Verilog Module:
this_block.setTopLevelLanguage('Verilog');
Note: The Configuration Wizard automatically selects the appropriate language when it
generates a configuration M-function.
