How to produce a VCD file when running Verilator with CEP 4.5

[jordankrim]

In CEP v4.4 one could add -v my.vcd to the simulator binary invocation with Verilator. Now I need to debug a hanging baremetal test in CE#P v4.5, but when I try to add that parameter, it gives an error that the -v parameter is not valid. If that is the case, how can I produce a VCD with Verilator?

OK. I forgot to add the --debug parameter to the verilator invocation, but when I do I get this failure where as without the --debug it compiles fine:

The --debug should not be necessary to produce a VCD file, so still doesn't work.
