2015.1 - SVF playback may fail depending on Cable used or OS used


Delays in the SVF file specified using the runtest_hw_jtag Tcl commands behave differently based on the cable type or OS.

An SVF/Tcl file played on an nt64 system using the DLC9LP (PCUSB2 with black pod) works at 6 MHz, but passes if DLC10 (PCUSB2 red pod) is run at 3 MHz.

The same SVF/Tcl file played on a lin64 machine using DLC10 passes if run at 750 kHz.


This will be fixed for the SVF production release in Vivado 2015.3.
