ChipScope PLBv46 IBA
(Bus Analyzer) (v. 1.00a, 1.01a)
DS619 April 7, 2009 Product Specification
Introduction
The ChipScope™ PLB Integrated Bus Analyzer (IBA) core
is a specialized bus analyzer core designed to debug embedded systems that contain the IBM CoreConnect™ Processor
Local Bus (PLB) version 4.6. The ChipScope PLB46 IBA
core in EDK is based on a Tcl script that generates an Hardware Description Language (HDL) wrapper to the PLB IBA
and calls the ChipScope Core Generator (Coregen) to generate the netlist based on user parameters.
The ChipScope PLBv46 IBA is a soft IP core designed for
Xilinx® FPGAs and contains the following features:
• Probes the master, slave, arbiter, and error status signals
of the PLBv46 bus
• Probes the PLBv46 OR'ed slave signals
• Automatically adjusts ports to the PLBv46 bus width
• Separates master, slave, and error status signals into
independent match units which can be enabled or
disabled by a design parameter
• Allows independent enabling or disabling of probed
master, slave, and error status signals for data capture
• Supports trigger port customization by a design
parameter
• Supports match unit type customization for each trigger
port by a design parameter
• Supports sample depths from 1024-131,072 on
Virtex™-5 Devices selectable by a design parameter
• Can probe as few as 1 signals and as many as 1115
signals on a Virtex-5 device
• Provides a separate input bus to allow a user-defined
input debug port
• Supports a trigger output indicator pin that can be sent
off chip or to other cores
