9.1i iMPACT - SVF file generation via iMPACT will not allow a max SDR shift length


XSVF files can be played over a JTAG chain to perform operations specified in the SVF file used as source code. Some of these applications which play an XSVF file have a maximum shift length that can be handled by the XSVF file player. How are files generated to compensate for this?


The iMPACT software does not currently support adjusting the shift length of a SDR or SIR value.

To do this, the svf2xsvf utility that ships with (Xilinx XAPP058): "Xilinx In-System Programming Using an Embedded Microcontroller" should be used with the -rlen switch.
