Hi.. I'm new user of SystemVerilog. I've download VMM standard libraries for Modelsim (Kit that is present on modelsim site). I'm using modelsim 6.3 version. My question is 1. Do modelsim 6.3 supports VMM based libraries or I need to have different version of modelsim?? 2. Do I need to compile all these libraries on command line OR is there some area where I can keep these libraries and modelsim will automatically pick them.?? -Deepti

You'll need Questa/Modelsim 6.3g or later to compile the VMM libraries, 6.5 was released a few weeks ago. However, you'll need Questa if you plan to perform any constrained random generation, assertions, or functional coverage collection. If you use compile the VMM as a package, you can just compile it once and import the package where needed. This is our recommended way of using any class library. Dave Rich Mentor Graphics

Hi this is rajeswar I am also user of systemverilog i am using the Modelsim 6.5 my modelsim 6.5 does not support the VMM libraries i think VMM libraries is only for synopssys VCS simulator plse send the link where you can download the vmm for modelsim

Please go to http://www.ovmworld.org, sign up for the forums there and download the OVM kit. The kit has a few basic examples and there are even more examples in http://www.ovmworld.org/contributions-details.php?id=54&keywords=OVM_Cookbook_Example_Kit Ask your questions over there as not to many people use this forum. It has difficulties posting Verilog code.

i am using the ovm/vmm interoperability libraries for running the vmm programs ion questa sim 6.4c i can down load the libraries from the mentor site it give the error ** Fatal: (vsim-3770) Failed to find user specified function 'vmm_str_match'. The search list was empty. # Using -sv_lib, -sv_root, and -sv_liblist arguments can provide a search list # of shared libraries that will be used to resolve user specified functions. # Time: 0 ps Iteration: 0 Instance: /dramtb File: dram_tb_top.sv # FATAL ERROR while loading design # Error loading design what can i do ?

You need to pass a library .so file to vsim for MTI to successfully run the simulation. Your vsim command will have to be modified. Add "-sv_lib $VMM_HOME/shared/lib/linux/vmm_str_dpi" to the vsim command

Hi, I am trying to compile the VMM examples provided using the modelsim6.4aSE. I got following error ---------------------------------------------------------------------- # ** Fatal: (vsim-3770) Failed to find user specified function 'vmm_str_match'. The search list was empty. # Using -sv_lib, -sv_root, and -sv_liblist arguments can provide a search list # of shared libraries that will be used to resolve user specified functions. # Time: 0 ns Iteration: 0 Instance: /tb_top File: D:/../../../../../Command_Master_Xactor/tb_top.sv # FATAL ERROR while loading design ----------------------------------------------------------------------- After looking at this posting I provided the .so library path as follows vsim "-sv_lib C:/../../../vmm-1.1.1a/shared/lib/linux/vmm_str_dpi" work.tb_top (since in the modelsim compiatble library which I have downloaded from OVM world there is no windows specific .so folder. So, I tried with .so library in linux folder) With the above modification I am still not able to load the design. I got following error -------------------------------------------------------------------------- # vsim -sv_lib C:/Documents and Settings/kotragoudh/Desktop/vmm-1.1.1a/shared/lib/linux/vmm_str_dpi -novopt work.tb_top # (vsim-3763) SystemVerilog DPI cannot access file '.\C:/Documents.dll' # Invalid argument. (errno = EINVAL) # Use the -help option for complete vsim usage. # Error loading design --------------------------------------------------------------------------- Kindly help me in fixing this. Thanks,

Keith

It looks like vsim does not like the spaces in the C:/Documents and Settings/ directory since it cant find Documents.dll. Try put quotes around the directory or copy your files to a directory with no spaces in the name. eg. vsim -sv_lib "C:/Documents and Settings/kotragoudh/Desktop/vmm-1.1.1a/shared/lib/linux/vmm_str_dpi" -novopt work.tb_top

Hi Keith, Thanks for your reply. Now I am able to run the VMM examples in QuestaSim. I used -sv_lib ../../../vmm-1.1.1a/shared/bin/win32/vmm_dpi_str.dll Regards, Kotragoud

Hi, Followed all instructions till the last post. Now i get new errors. Copied below, Error: (vsim-3193) Load of ".\../vmm_libs/vmm-1.1.1a/shared/bin/win32/vmm_str_dpi.dll" failed: DLL dependent library not found. # Fatal: (vsim-3748) Failed to load DPI object file ".\../vmm_libs/vmm-1.1.1a/shared/bin/win32/vmm_str_dpi.dll" while trying to resolve 'vmm_str_match'. Any ideas what am missing? I use Questa v6.5b. Thanks, Prashanth

Ok appears to be a beginners mistake. +define+VMM_NO_STR_DPI must be a compile time option not for simulation. eg: vlog -sv -mfcu -f flist +define+VMM_NO_STR_DPI vsim work.top the -sv_lib option isnt necessary in this case.
