B-V-F

Description

This repository can be used to generate a reference design for the B-V-F. This reference design will have the same or extended functionality compared to the pre-programmed FPGA design on the B-V-F.

A Libero SoC Tcl script is provided to generate the reference design using Libero SoC along with device specific I/O constraints.

This repository supports Libero SoC v2021.3, which is available for download here.

Using the reference design generation Tcl script

Standard design generation

To generate the standard reference design which is capable of running the majority of bare metal example applications and run Linux® the following flow can be used:

1. Clone or download the repository
2. Open Libero v2021.3
3. Open the execute script dialog (CTRL + U)
4. Execute the "B_V_F_REFERENCE_DESIGN.tcl" script
5. Configure the design if required
6. Run the Libero SoC design flow to program a device
