I'm working with FPGA's that use STAPL bitstreams. In addition to the standard configuration bitstream, I'd also like to input custom (proprietary) JTAG commands and bitstreams.
All the STAPL documentation I've looked at implies that a piece of software they call STAPL composer performs this function (i.e. generates the STAPL scripting file) However, the discussion never proceeds beyond this point. No manufacturer, no external website, seems to give details on or even roughly describe the STAPL Composer, much less offer one for download.
It seems as though the FPGA development tools tend to embed functionality which acts in the capacity of a STAPL composer in the bitstream-generation utility, but this functionality is strictly limited to the configuration bitstreams, not to mention the specific FPGA company in question.
So, is there a STAPL Composer out there which will allow me to generate custom STAPL files, inserting user-specified bitstreams and JTAG commands? Ideally this program would also be able to create STAPL files for FPGAs from multiple different companies. I'd like to find some solution for configuration, programming, and test that does more than the dedicated task of loading a configuration bitstream for a specific manufacturer's FPGA's.
