need 32bit version of modelsim libmodelsimpli.so

[張哲文]

Hi

i am doing "sims -sys=manycore -x_tiles=1 -y_tiles=1 -msm_run -ariane hello_world.c -rtl_timeout 10000000"

Error (vsim-125) The shared library /piton/tools/linux/x86_64/lib/libmodelsimpli.so being loadded was built on a 64-bit machine, A 64-bit shared library cannot be loaded in a 32-bit simulation. 

wrong ELF class:ELFCLASS64

I use ModelSimSetup-20.1.1.720-linx.run

Could someone help? thank you

Owen

Hi Owen,

I think you're perhaps running the free, 32 bit version of modelsim? It isn't supported by default and requires some changes. There's a (recently closed) pull request on the openpiton repo which should provide a patch that you could apply. Note that I seem to remember it was said to run very slowly. You may have a better time trying verilator or another simulator instead depending on your needs.

Thanks,

Jon

Hi Jon,

thank you. from sims i only saw ncsim, vcs, iverilog, riviera supported (no verilator?), I have tried iverilog  but failed with  "sims -sys=manycore -x_tiles=1 -y_tiles=1 -icv_build -ariane hello_world.c"

error message: 
openpiton/piton/design/chipset/rv64_platform/bootrom/baremetal/bootrom.sv:255:error: invalid module item

openpiton/piton/design/chipset/rv64_platform/bootrom/baremetal/bootrom_linux.sv:23: syntax error

openpiton/piton/design/chipset/rv64_platform/bootrom/baremetal/bootrom_linux.sv:23: syntax error or localparam list

i don't have commercial simulator in my environment

Verilator is supported, as noted in the readme and the sims help output: https://github.com/PrincetonUniversity/openpiton/blob/41a14a05010023d1be013cc16eafb0c4b86af595/piton/tools/src/sims/sims%2C2.0#L3348

Icarus does not supported sufficient systemverilog to build the design.

Thanks.

I just installed Verilator (using ariane/ci/install-verilator.sh, version 4.014) and run it "sims -sys=manycore -x_tiles=1 -y_tiles=1 -vlt_build"

and got error:

openpiton/piton/tools/verilator/my_top.cpp:41:17 error : conflicting declaration of C function "void init_jbus_model_call(char*, int)"

from Vcom_top__Dpi.h:21:17: extern void init_jbus_model_call (const char* str, int oram)

do you have any suggestions? thank you

You can go into the my_top and iob_main files and align the declaration with the use. It's just const char * vs char * which some compilers are unhappy about now. You may also need to remove build/manycore/rel-0.1/obj_dir/ before you rebuild.

Thanks,

Jon
