Quartus II Design Examples: Examples for lpm_shiftreg Megafunction
The lpm_shiftreg Megafunction User Guide provides two design examples to implement a configurable 8-bit serial in parallel out (SIPO) or parallel in serial out (PISO) shift register and time delay functionality. Both the design examples use the MegaWizard® Plug-In Manager available in the Quartus® II software. The steps to generate the megafunctions using the MegaWizard are described in detail in the User Guide.
Design Example 1: Configurable 8-Bit SIPO or PISO Shift Register
This design example illustrates the use of lpm_shiftreg megafunction to implement a configurable 8-bit serial in parallel out or parallel in serial out shift register. In this example, you do the following.
- Create an 8-bit shift register using the
lpm_shiftreg megafunction and the MegaWizard Plug-in Manager
- Implement the design and assign the EP1S10F780C6 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
Design Example 2: Time delay
This design example uses the lpm_shiftreg megafunction to implement time delay functionality. In this example, you do the following:
- Create a time delay using the
lpm_shiftreg megafunction and the MegaWizard Plug-in Manager
- Implement the design and assign the EP1S10B672C6 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
