Dumping a vcd file starting from a "RST" transition to high until the end of simu

Hi, i am writing a tcl file to run simulation on ncsim.
i need to dump a vcd file starting from a "RST" transition to high until the end of simulation automatically.
please suggest a tcl script template to run the dumping.
thanks.

In modelsim you could create breakpoint on certain signal and activity, so to control the start &stop of your sdc

I used $dumpoff / $dumpon directives inside your testbench.

You can use "when" command

when -fast {reset == '1'} {
vcd on
}
