Hi,
I'm trying to use a DPI-C function in my SV env (creating a dpi.so lib and running it using VCS):
"vcs -debug_all -full64 -sverilog -R file.sv dpi.so"
This works fine for "basic" C functions.
Now my "dpi.so" library contain a function that uses another shared library, say utils.so (The reason for using it, is that utils.so contains some functions I need to use, supplied by 3rd party, but the argument they accept are structs defined in C header file).
When I try compiling it I get the following error:
And get the compilation error:
when I try compiling for C++:
And got the following:
How can I compile a DPI when the C code uses another shared lib?
Does anyone have any experience in using this C model supplied by Xilinx IP for verification in SV?
Thanks
