Load Path

Format

x <ipname>_vX_Y_Z.bbd

Load Path

Refer to Figure 14-1 for a depiction of the peripheral directory structure.

To specify additional directories, use one of the following options:

x Current directory

x Set the EDK tool option -lp option

EDK tools use a search priority mechanism to locate peripherals, as follows:

1. Search the pcores directory in the project directory

2. Search <library_path>/<Library Name>/pcores as specified by the -lp option

Search XILINX_EDK/hw/<Library Name>/pcores

Using Versions

You can create multiple versions of your peripheral. The version is specified as a literal of

the form 1.00.a. The version is always specified in lower-case.

At the MHS level, use the HW_VER parameter to set the hardware version. The Platform

Generator concatenates a "_v" and translates periods to underscores. The peripheral name

and HW_VER are joined together to form a name for a search level in the load path. For

example, if your peripheral is version 1.00.a, then the MPD, BBD, and PAO files are found

in the following location:

<repository_dir>/pcores/<ipname>_v1_00_a/data (UNIX)

<repository_dir>\pcores\<ipname>_v1_00_a\data (PC)

Creating User IP

To build your own reference depends on the characteristics of your design.
