SystemVerilog DPI in NCSim?

archive

Hi all, Because it will take some time waiting download IUS583, I tried to use SystemVerilog DPI (mostly imported functions). I heard that Synopsys can simply include C file in file list with SystemVerilog file and run simulation. But Cadence NC seems need C code compile and link to a lib. I have read the NCsim document and find a switch "-sv_lib". But I cannot find a simple example. Is there any step by step tutorial about how to compile, link and run SystemVerilog DPI C file in NCsim? Best regards, Davy

  • Hi,
    I am seeing following errors while using ncsc_run:
    ncsc: compiling $TESTDIR/adder_sysc_main.cpp
    make: *** [INCA_libs/ncsc_obj/adder_sysc_main.o] Error 1
    ncsc: *W,WRKNMP: Could not obtain library mapping for WORK, no SystemC intermediate form generated.
    ncsc: Error executing: $CDSROOT/tools/systemc/gcc//bin/g++ -o INCA_libs/ncsc_obj/adder_sysc_main.o -DNCSC -I$CDSROOT/tools/systemc/include -I$CDSROOT/tools/tbsc/include -I$CDSROOT/tools/vic/include -I$CDSROOT/tools/systemc/include/tlm -c -x c++ -Wall $TESTDIR/adder_sysc_main.cpp
    ncsc_run: *E,TBBLDF: Failed to generate object INCA_libs/ncsc_obj/adder_sysc_main.o


    Any idea why I am seeing this error?
