Using ChipScope with

OPB IIC

To facilitate the use of ChipScope to analyze OPB IIC hardware, the iic.cdc ﬁle is included in the ml403_ppc_opb_iic/chipscope directory. The iic.cdc is used to insert a ChipScope ILA core into the opb_iic core. The following steps are used to insert a core and analyze OPB IIC problems with ChipScope.

1.Invoke XPS. Run Hardware → Generate Netlist.

2.In the iic.cdc ﬁle, change the path <design_directory> name to the directory in which the design ﬁles are installed. Three paths need to be changed.

3.Run Start → Programs → ChipScope Pro → ChipScope Inserter

4.From ChipScope Inserter, run File → Open Project ii.cdc. Figure 22 shows the ChipScope Inserter setup GUI.
