Load Path

Refer to Figure 5-1 for a depiction of the peripheral directory structure.

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

x Current directory (where PlatGen was launched; not where the MHS resides)

x Set the EDK tool option -lp option

PlatGen uses 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

3. Search XILINX_EDK/hw/<Library Name>/pcores

From the pcores directory, the peripheral name is the name of the root directory. From the

root directory, the underlying directory structure is as follows:

data

hdl

netlist

simmodels

Output Files

PlatGen produces the following directories and files. From the project directory, this is the

underlying directory structure:

hdl

implementation

synthesis

HDL Directory

The hdl directory contains the following:

system.[vhd|v]

This is the HDL file of the embedded processor system as defined in the MHS. This file

contains IOB primitives if the -toplevel yes option is specified.
