Quartus II Design Examples: Examples for alt_fp_add_sub Megafunction
The alt_fp_add_sub Megafunction User Guide provides two design examples to implement an adder for the addition of double-precision numbers and a subtractor for the subtraction of single-extended precision numbers. These two design examples use the MegaWizard® Plug-In Manager in the Quartus® II software. The steps to generate the megafunction using the MegaWizard Plug-In Manager are described in detail in the User Guide.
Design Example 1: Addition of Double-Precision Numbers
This design example uses the altfp_add_sub megafunction to implement an adder for the addition of double-precision numbers.
In this example, you do the following:
- Create an adder using the
altfp_add_sub megafunction and the MegaWizard Plug-in Manager
- Implement the design and assign the EP1S10F780C5ES device to the project
- Compile and simulate the design
The following design files are used in this example:

Design Example 2: Subtraction of Single- Extended Precision Numbers
This design example uses the altfp_add_sub megafunction to implement Subtractor for the subtraction of single-extended precision numbers.
In this example, you do the following:
- Create a subtractor using the
altfp_add_sub megafunction and the MegaWizard Plug-in Manager
- Implement the design and assign the EP1S30F780C5 device to the project
- Compile and simulate the design
The following design files are used in this example:
- The Quartus II project archive
- README file
