waveform dump

Hi,

I'm trying to dump all DUT signals in a .trn file. A .trn file is getting created when i use
$recordfile("filename.trn");
$recordvars();

but this file doesnot contain any signals or dump. Please guide me on how to dump all dut signals internal to the DUT as well in IUS5.83.

Thanks

+access+rcw for ncverilog command and -access+rcw for nc elaboration

Just for the record: the rcw flags can be used to specify exactly how you will interact with the simulator.
If you will only want to probe waveforms, then "-access +r" is enough, because the "r" flag turns on read access to the design.
If you want to use TCL commands like "force", or you have PLI / VPI code that drives signals, then you need to add the "w" flag.
Finally the "c" flag turns on connectivity tracing, to allow the SimVision debug stuff like "trace drivers" to work.

Hope this helps.
