No, you can step a second and subsequent times by setting

This is a good pointer for debugging. The system clock may have been stepped,
but the FPGA hardware clock is not stepped and continues to provide the

Hello,
I have a couple of questions about the frequency limit. How much may it be
reasonably increased from the default of 2 (20%)? And this parameter is
only configurable via the config file. Is that correct?

only configurable via the config file. Is that correct?
