FPGA pin toggle via boundary scan

[e.charre]

Hello,

I am looking for a solution to toggle a FPGA pin using JTAG probe.

I am developping with ISE 9.2.04i and the target is a Virtex II : XC2V1500.

The pin I want to test is "INIT_B", so I cannot make a design to test it. So, I'd like to use JTAG way.

Can I use iMPACT to execute a SVF file [edit] using batch command [/edit]?

If YES, could you give me an example of SVF file ?

Else, is another way is possible to toggle a pin, only using Xilinx tools ?

Thank's

Emmanuel.

You can sample and drive pins via boundary-scan using TopJTAG Probe http://www.topjtag.com/probe/ software. It's not a Xilinx software, however, it can work with Xilinx parallel port cables and some other USB cables.

VERY NICE !!

Thank's for this link, it is exactly what we need, with a very little price.

Do you know a software like this one which intergrate ATE function (Automatic Test Equipment) like "XJTAG" but compatible with Xilinx probe ?

Thank's again.

Emmanuel.
