I maked the lowrisc-chip project by the 'make vivado' and successfully run synthesis, generated the bistream and programmed the Nexys4_DDR board. But when I run behavior simulation in vivado, I meet an error like
[USF-XSim-62] 'elaborate' step failed with error(s) while executing '/home/tools/lowrisc-chip-refresh-v0.6/fpga/board/nexys4_ddr/lowrisc-chip-imp/' script. Please check that the file has the correct 'read/write/execute' permissions and the Tcl console output for any other possible errors or warnings.
I have 'chmod 777' the script but its useless. Then I check the 'elaborate.log', but there is only warning, no error.
How can I get more accurate messages and find bug.
In addition, I have try that deleting the 'xsim' folder, reloading the project and restarting the vivado, which is all useless.
Can I get some help?

Kindly have a look at elaborate.log file. If you see no information in that log, please share your design with us along with OS and vivado version.

Thanks for your kindly regards.
My vivado version is 2018.3 and OS is ubuntu16.04 which is recommended by Lowrisc.
As for my design, I dont change any part of it, and I just want to run the behavior simulation to check the waveform. This project is same to the project in Lowrisc.org.
I attach the elaborate.log and hope I would do a little help.

We do not have access to get the design from website, Kindly provide us the design. Also, please try xelab command with '-v 2' switch to get more information.
