EDA Interfaces

Overview: Creating & Instantiating Altera-Provided Functions in Other EDA Tools

You can use Altera-provided megafunctions in other EDA tools by using the MegaWizard® Plug-In Manager (Tools menu) to create and instantiate custom megafunction variations that are based on Altera-provided megafunctions, including library of parameterized modules (LPM) functions, as well as Altera® megafunctions

The following examples show how to create a Verilog HDL or VHDL design using the specified EDA tools. Although one example is provided for each tool and each type of megafunction, you can use the same procedures and principles to create similar designs for other megafunctions or other EDA tools.

NOTE If you are using the Synplify software, and you want to use the lpm_mult, lpm_ram_dp, lpm_ram_dq, lpm_rom, lpm_latch, or lpm_ff LPM functions, refer to Create a Design for Use with the Synplify Software.
