Ask a question related to Ibex, behavior simulation error in Vivado

[twyayaya]

Hello, recently I have been trying to generate a .xclbin file using Vitis and Vivado, using ibex as the kernel code.

During this process, I encountered some errors in Vivado. Initially, I ran the behavior simulation using only the files under the ibex-master/rtl directory, with Ibex_top.sv as the top module.

However, Vivado showed errors indicating that some package files were missing. To resolve this, I included all the files from the directories where those missing files were located as sources for running the behavior simulation. Based on the error messages, I selected the following directory files to use as my source:

ibex-master\rtl\
ibex-master\vendor\lowrisc_ip\ip\prim\rtl\
ibex-master\dv\uvm\core_ibex\common\prim\
ibex-master\vendor\lowrisc_ip\ip\prim_generic\rtl\
ibex-master\vendor\lowrisc_ip\ip\prim_xilinx\rtl\
dv_fcov_macros.svh

After including these files, Vivado's messages did not show any missing files, but the error message indicated issues with a few lines in my xsim_3.c file, like this:

xsim.dir/code_tb_behav/obj/xsim_3.c:140:25: error: expected initializer before ‘.’ token
int gen_prefetch_buffer.simutil_get_scramble_key(svBitVecVal arg0[SV_PACKED_DATA_NELEMS(128)])

As xsim_3.c is automatically generated by Vivado, I am now considering the possibility that some of the sources I selected might be incorrect, leading to this error.

My Environment

EDA tool and version:

Vivado 2020.2

Operating system:

Ubuntu Linux 18.04
