Xcelium -> usage of xrun command

Hello,

For running a simulation, I'm using the following command:

%>  xrun top_tb.sv -f files_list -gui -access rwc &

where the top_tb.sv is the TestBench and files_list is a list of RTL files, which should be simulated.

After running the 'xrun' command, the waves.shm and xcelium.d directories have been created.

As for my understanding, the xcelium.d is a working directory (what should it include?) and the waves.shm directory where the TRN and DSN files are stored.

1) the TRN files have been split during the simulation, each TRN file is about 0.5MB (500KB). Is there a way to manage the size of the generated TRN files?

2) is there a way to give a custom name to the simulation database? how?

3) could the xrun command be ran without the '-gui' switch? How then to see the waves?

Thank you!
