The absence of error or warning messages indicate that the SVF file was
executed without problems. To get a progress reporting while the player advances
through the SVF file, specify 'progress' at the svf command.

- TIR, TDR commands not supported. +
Their functionality should be covered by the part concept of JTAG Tools.
Operation can be slowed down significantly when the FREQUENCY command has
been specified. This is not a problem of the SVF player itself but seem to
happen when the frequency of UrJTAG is set to a value larger than 0.
Configuration takes very long although the maximum allowed frequency is 10 MHz.
Consider to comment out the FREQUENCY command at the beginning of the SVF file.
SVF files for programming flash-based devices might or might not work for a given
setup. This has been observed for Actel IGLOO devices where success and failure
depends on the actual clocking rate of the chosen cable.
The ref_freq=<...> option to the svf command allows to tweak the calculation
of 'RUNTEST xxx SEC' commands. For these commands, the SVF player needs to
calculate the equivalent number of clocks and per default it will use the
current cable clock frequency. This can be overridden with the ref_freq option
that specifies a fixed reference frequency for such calculations.
