Question about design synthesis

[DCliuzhe]

Hello, I have a question about synthesizing ara.
I want to use dc_shell to synthesize ara and obtain the PPA. I follow the solution mentioned in #333 and use bender to generate .tcl file:
./bender script synopsys --define NR_LANES=4, --define VLEN=4096
But the design compiler reports numerous error messages in the phase of design files compilation, did I use the bender correctly or miss some necessary steps?
