A XSVF assembler/disassembler in python

Tuesday, September 8th, 2015

Marcelo Roberto Jimenez wrote an assembler/disassembler for XSVF, he writes: As a sequence of my last project, the JTAG/XSVF library for Arduino, I felt I needed a XSVF assembler and disassembler, so that I could hack JTAG a little bit. I found that XSVF is very convenient, much more than...

A JTAG/XSVF library for Arduino

Wednesday, August 19th, 2015

Marcelo published a post on his blog about JTAG and the library he wrote. I have recently felt the need to incorporate a JTAG port in a project to program a hardware that contained a CPLD. The idea was to both program it and perform some integrity tests on the...

Integrating the XSVF player into Bus Pirate firmware

Tuesday, April 10th, 2012

Jean modified the Bus Pirate firmware to integrate the standalone XSVF player into it. The XSVF player is an alternate firmware for the Bus Pirate that allows it to program CPLDs and FPGAs via XSVF files. I have integrated the support of XSVF Player within the current 6.1 BP firmware...

One step XSVF file generation for CPLD

Monday, July 4th, 2011

If you're using one of our CPLD Development Boards you need to have a file in XSVF format to download to the board using the Bus Pirate loaded with the BPXSVFPLAYER firmware. We've posted a method to convert SVF files to XSVF format, but Xilinx has included a handy way...

XSVF specification document

Sunday, February 20th, 2011

We've referred to various file formats for programming CPLDs and FPGAs in recent posts. One is the Serial Vector Format (SVF), an industry standard file format that is used to describe JTAG chain operations in a compact, portable fashion. Its specifications are fully described in this 26 page PDF produced...
