IUS version for OVM

[ayari]

Hello,

with which IUS version can i run the OVM examples? (a short demo on some example would be very helpful!)

Thanks

[stuart]

OVM 1.0 works with IUS 6.2-p1 and later releases. All OVM examples are run with the command:

irun -f compile_ius.f

Hi,

Incisive license for irun 6,2 is not available to universities.
Is there any way to run OVM without irun, using ncverilog 6.2 or alike ?

Thanks

[pjigar]

If you have IUS 6.2 installed then you have access to irun utility. It is very similar to ncverilog but in addition to Verilog and SystemVerilog, irun can accept VHDL, e, SystemC, AMS, etc.

[elmar]

Correct, I can launch irun but I get errors messages because I do not have the license to run it. This is because I am a university professor and the Cadence University license does not inlcude irun. So my question is this:

Do I absolutely need irun to use OVM or is there any other tool from IUS 6.2
which is able to support OVM?

I am only interested in SystemVerilog and not in VHDL, nor SystemC, nor AMS (at least not at this moment).

Hi,

You can use ncverilog with IUS6.2 to run OVM. Do you have access to ncverilog?

See a simple example below.

file ncver_test.sv

module test;
`include "ovm.svh"

class test1 extends ovm_test;
`ovm_component_utils(test1)
function new(string name, ovm_component parent);
super.new(name, parent);
endfunction

task run();
`message (OVM_NONE, ("Running test1"))
endtask
endclass

initial run_test("test1");

endmodule

To run the example, you can use ncverilog or 3 step compile process by first running svpp as shown below.

1) `ncroot`/tools/urm/bin/svpp -incdir $OVMHOME/src ncver_test.sv
2) ncverilog +sv +incdir+INCA_libs/svpplib/specials +incdir+INCA_libs/svpplib/$OVMHOME/src INCA_libs/svpplib/ncver_test.sv +nowarn+PMBDVX

Hi Umer,

I have access to ncverilog, like so:

file hello.sv

module hello;

logic [3:0] a;
initial begin
a = 3;
$display("Hello ", a);
end

endmodule

ncverilog +sv hello.sv
...
ncsim> run
Hello 3
...


However, when I try Your example I get:
Trying to check out license...
Incisive_Verif_Engine 6.2 - Failed
Incisive_Design_Team_Simulator 6.2 - Failed
Incisive_Enterprise_Simulator 6.2 - Failed
ncsim: *F,NOLICN: Unable to checkout license for the simulation. (flag - 10) 'lic_error -18'.

just the same what I get when I use irun.

Perhaps it is really svpp, not only irun, that needs the Incisive lincese ?

Elmar

Hello Elmar,

svpp does not consume a license.

To run OVM, the simulator checks out a Design Team Simulator license. Please contact your Cadence Account Manager to get the correct license or you can send me an email and I can put you in touch with the right person.

Thanks,

Umer

Hi, All.

I've found same trouble with IUS8.1 (08.10-s003).

The examples from ovm folder (ius/tools/ovm) do not compile either with ncverilog -ovm nor with irun -f compile_ius.f command.

I use the following options in compile_ius.f


+OVM_TESTNAME=test

+incdir+/usr/ius81/tools/ovm/src

-nowarn PMBDVX

-svpp -q

BUT example from umery compiles and works with simple
irun -ovm file.sv

Is some dedicated options/environment required to run OVM examples under NCVERILOG?
What I should do to run the examples?

BR,
Sergey.

For the trivial example, you will need to compile the ovm_pkg. You can use the following command to compile the ovm_pkg & the trivial example:
irun +incdir+../../src ../../src/ovm_pkg.sv component.sv -ovm

Or you can change your compile_ius.f to:
+incdir+/usr/ius81/tools/ovm/src
-nowarn PMBDVX
-svpp -q
/usr/ius81/tools/ovm/src/ovm_pkg.sv
component.sv

For the hello_world example, please use the command below:
irun +incdir+../../../src/ -ovm hello_world.sv

BTW, you can use "-ovm" to replace "-nowarn PMBDVX -svpp".

[syemets]

Thank You.
The examples work.

BR,
Sergey.

[syemets]

It is better to take ovm sources from this site than from IUS distribution.

IUS exampes do not include compile file lists (compile_ius.f).
So it is required some additional efforts from beginer to write the files.

Sergey.
