MODELSIM : C,TCL,Verilog simulation?

[Pasacco]

Hi

I need following help with MODELSIM

How to do "C + TCL + Verilog" simulation.

Verilog code contains following statement.

------------------------------------------
initial $benchC(1, "Tcl", filename);
------------------------------------------

'benchC' is written by C code.

When I simulate the module, following warning is encountered.

------------------------------------------
* Warning: (vsim-PLI-3003) /opt/data/RTL/testbench.v(123): [TOFD] -
System task or function '$benchC' is not defined.
------------------------------------------

My question is that

How can we compile (or call) C codes and simulate, together with
Verilog codes.

If will be grateful if someone point me out any well-described
document (for beginner) about

------------------------------------------
How to do simulation "C + Verilog" or "C + VHDL"
and
How to do simulation 'TCL'
------------------------------------------

Thank you in advance

Hi!
Check out the documentation that comes with the installation.
Click on Help->PE_PDF_Manuals->ModelSim_PE_PDF_CookCase
In that select the users manual, in which there is an section on
Verilog PLI

Let me know if that helps

Hi

Modelsim isn't good simulator for verilog PLI (Programming Language
Interface), you can use Synopsys VCS simulator for this work.

Well I have not seen any problems with Modelsim regarding PLI
functionality. I have used some homemade and also commercial
PLI libraries with no problems.

I guess in the original message the problem was just how to compile
and how to tell modelsim to load the PLI library. That is explained
in the manual very throughly.

Usually when you have pli/vpi functions that are compiled, you need to
pass the library name (a .dll on windows or .sl on *nix) to the
simulator using "-pli <library anme here>". Most probably your benchC
is compiled into a library, you need to find that. And that creates a
TCL interpreter and loads your tcl file and drives your testbench.
