Hello,


I would like to use the simulation software xrun/simvision that comes with XCELIUM. We are currently using classroom licenses and want to disable all ip addresses on the student pcs except the license server ip. We want to make sure that students cannot copy confidential data from the Cadence tools.


Problem:

When I launch the xrun simulation while all ip addresses are blocked, it starts but the performance is very slow. The GUI starts after 5 minutes and the simulation is ready after 10 minutes. The interesting thing is that when I enable all blocked ip addresses, everything works at a reasonable speed.

Terminal Output (execution without internet connection):

xrun -gui design.vhd

waiting for SimVision/Verisium Debug to connect...


Is there a way to run the simulation tools without an Internet connection? Or can you give me the ip addresses that are used by the simulation tools so that I can enable only those specific ips?


Regards,

Max

I'm completely new to Cadence. I've been able to run a very simple simulation with the -gui option. Simvision opens, I add the variables to the waveform viewer, and press run. All is good.

I don't understand the flow when using the -nogui option. It appears that the simulation runs and returns control to the OS. When I launch Simvision, is there a database or file that I can open to display the already-simulated data?

My command is of the form:

xrun -gui -64bit -sv -access +rwc -top tb_top.sv <src files>

I want to do a 2-step build->simulate as follow:

1. Make multiple builds using xrun -elaborate [other options]. The purpose is to create multiple builds with different compile-time macros (+define+MACROA +define+MACROB=ABC). Each build is located in a different directory.

2. Run simulation with xrun -r. This is where I need help. How do I specify which build to simulate? Also, I need the simulation directory (with log files, …) to be different than the build directory.

Has anyone been able to achieve this or similar solutions?

We are trying to run compilation, elab and sim with command xrun -r -u alu, where alu is one of the units to execute. we are getting the following errors.

1) xmsim: *E,DLMKDF: Unable to add default DEFINE std       /home/xxxx/Cad/xcelium/tools/inca/files/STD.
    xmsim: *E,DLMKDF: Unable to add default DEFINE synopsys  /home/xxxx/Cad/xcelium/tools/inca/files/SYNOPSYS

2) xmsim: *W,DLNOHV: Unable to find an 'hdl.var' file to load in.

What is the purpose of hdl.var

3) xmsim: *F,NOSNAP: Snapshot 'alu' does not exist in the libraries.

I cannot see in log files, which libraries is it referring to??

Any one request you to help on how to debug these.

Hi all,

I need to develop a digital design/verification solution to compile,elaborate and simulate SV designs (basically a complex xrun wrapper). I am an experienced user of xrun and I have done a number of these wrappers over the years but this one is to be more of a tool, intented to be used Company-wise, so it needs to be very well thought and engineered.

It needs to be robust, simple and extensible. It needs to support multi-snapshot elaboration, run regressions on machine farms, collect coverage, create reports, etc.

I've been browsing the vast amount of documentation on XCELIUM and, although very good, I can't find any document which puts together all the pieces of what I am trying to achieve. I suppose I am more clear on the elaboration, compilation and simulation part but I am really lacking on the other areas like : LSF, regressions coverage, where does vManager fits in all this, etc.

I'd appreciate if someone can comment on whether there is a document which depicts how such a DV flow can be put together from scratch, or whether there is a kind of RAK with some example xrun wrapper.

Thanks

Hi,

I found a basic Specman E/Verilog program at http://www.asic-world.com/examples/specman/memory.html and I would like to run it through a vsif file, with vManager.

I'm able to run it, without problems, with this command : xrun -Q -unbuffered '-timescale' '1ns/1ns' '-access' '+rw' memory_tb.v mem_tb_top.e test_write_read_all.e.

I wrote a first vsif which look like this:

---- vm_basic.vsif -----

session vm_basic {
        top_dir : /home/cadence/xrunTest/;
        output_mode: terminal;
};

group basic {
        test test {
                run_script: xrun -Q -unbuffered '-timescale' '1ns/1ns' '-access' '+rw' memory_tb.v mem_tb_top.e test_write_read_all.e
        };
};

----------------------------

This solution didn't work due to the prompt change with xrun, and I have no clue how to manage this issue.

Have you any idea?

Best regards,

Yohan
