Simulating Rocket Chip in DVE with Program

Hello everyone!
I'm trying to visualize a DefaultConfig of Rocket Chip on Synopsys DVE.
I have done "make" in vsim folder and It has generated the executable :

simv-freechips.rocketchip.system-DefaultConfig

Now I want to add my simple C program to Rocket memory to see if it works.
I have generated the executable and then I have tried this command to launch DVE:

dve -full64 -toolexe simv-freechips.rocketchip.system-DefaultConfig /file_c/matrix2

or

dve -full64 -toolexe simv-freechips.rocketchip.system-DefaultConfig +exe=/file_c/matrix2

but I receive this error:

Warning: Unknown command line arg: /file_c/matrix2

what is the best method to load the program onto the rocket and then launch DVE?

Start with the vsim folder's generated simv-freechips.rocketchip.system-DefaultConfig executable and the reported DVE command-line arguments. Check how this simulation accepts a program image and how DVE forwards arguments; done means identifying a working invocation that loads /file_c/matrix2 without the unknown-argument warning.
