EZTag with Workstations

design.jed

The design.jed file contains the configuration information for the

target design in JEDEC 3-C standard formats. The file is generated by

the fitter software. This file may optionally contain functional test

vectors to do functional verification of XC9500 devices.

The eztag.pro ﬁle contains the default values for all EZTag options:

part, design, baud, and port. These option values are updated at the

end of every EZTag session. For EZTag to recognize an xchecker.pro

ﬁle, it must be located in the same directory in which you started the

EZTag software.

batch_ﬁle.cmd

The batch ﬁles are text ﬁles used to execute commands in the batch

mode, and the extension ".cmd" is required.

The bsd ﬁles contain Boundary Scan Description Language (BSDL)

speciﬁcations of the operation of the boundary-scan logic of a given

device. For any non-XC9500 device in your boundary-scan chain, you

are required to supply this ﬁle.

You can start EZTag using any of the following methods:

You can download a design after connecting the XChecker cable to

the host system and target system. To download a design, enter the

4-2

Command line entry from the system shell. Only download and

verify are supported. You cannot interactively probe the internal

logic. Command line entry can only be used when there is exactly

one device in the boundary-scan chain.

Interactive commands from the system shell. This mode offers

additional commands for download and readback and also allows

you to probe the internal logic states of the target system device.
