Getting Waveforms on Xtreme Box.

Hi DGill,

The way to get waveforms for the DUT signals on the Xtreme platform when running in SW mode is to do a $dumpvars and debug using the post-process mehod. Similarly the HW waveforms can be generated using the VCD on Demand (VoD) feature after the simulation has been run once and use the post-process method.

The Xtreme platform does not support the continuous waveform feature. If you need help in generating VoD waveforms do let us know.

One way to generate continous waveform of a limited number of DUT signals in Xtreme is to $export_read the signals of interest.

initial
begin
$export_read();
$export_read();
...
end

and then use regular $dumpvars for those signals at runtime. This is only available if you using $rcc(run) mode.

One should not use more than few hundred signals in this way or it will impact runtime perfomance.
