Spectre failed to complete the simulation with Error ID=5011

Not really enough information to go on (you didn't say which IC version you're running from, whether it's ADE L, XL, Explorer, Assembler). Also you're running a version of Spectre from over 6 years ago - is there a good reason why you have to use something that old?

Did the simulator log give more details - that's more likely to give a clue as to the reason for the simulator exiting early.

Hi Andrew,
Thanks for quick reply.
Here are the details you have asked:
IC version: IC617
I am running an ADE-XL environment. We have university owned tools, So we don't have any reason  for using the old version, But since you advised, I'll talk to the concern person regarding updating the tools. Could you please suggest how it can get updated or quick fix to the issue.
The simulator only gave reasons I have mentioned above:

 *Error* Error ID = 5011
 *Error* Error Msg = Simulator failed to complete the simulation.

 The simulator could have crashed or
 intentionally returned to indicate an error.
 Check the simulator log file for more information. Common causes:
1. Simulator may have crashed during exit even after reporting  success in log file.
2. Abrupt automatic simulator termination (e.g., SIGKILL) because the simulator process has exceeded resource limits, which can be specified in  the distribution system or by the kernel itself (e.g., the Linux OOMKiller).
3. Manual termination of the simulator process. ./runSimulation can be manually run in  this directory to check the issue.

Also, I see few times virtuoso pops-up notification for low memory. 

Please let me know if you need any more info in order to understand the issue better.

Regards,
Shubham

Shubham,

You mentioned that it is running for 2ns - if so, you're presumably looking at a spectre log file somewhere (otherwise how would you know that it ran for 2ns?). That's what I want to see rather than a message in the CIW.

Dear Shubham,

Just to add to Andrew's comments and questions if I may, you indicated a few items that relate to your error directly:

I am running a post layout simulation by providing a SPICE post layout netlist (in a config view).

The job is running for a very short duration (2-5ns), while the total run time is 80ns.

Your error indicates :

2. Abrupt automatic simulator termination (e.g., SIGKILL) because the simulator process has exceeded resource limits, which can be specified in  the distribution system or by the kernel itself (e.g., the Linux OOMKiller).

It certainly seems a possibility that your simulation job requires more resources than you have provided for it to run successfully. The combination of using an extracted view and that it terminates prematurely, and that you observe "pop-up" dialog boxes indicating a low memory status suggest this to me. 

1. Have you tried running on a distributed machine where you can increase the memory allocation and use multiple cores?

2. Are you using spectre APS to run the simulation?

3. Did you examine the job resources following the termination?

4. Are you sure the format being written is psf and not a SPICE format? If so, you might check the On-line support article regarding this error at:

Only place where error mentioned is:

But the simulations kept on going on and stopped after few nano second as mentioned earlier. Also, It stopped while still performing transient analysis (no error or warning displayed when job stopped running) in GUI it simply shows job completed.

Please let me know if you need any further information.
