parametric analysis error

Hi,

For both IC5.0.33 and IC5.1.41, after I run a parametric analysis in
the Analog Design Environment, I cannot run it again. I get the
following error in the CIW:

*Error* request.il asiiFinish: error in finish function ("deleteFile"
59 t nil ("*Error* deleteFile: device or resource busy"
".../psf/.nfs..."))

I cannot delete the .nfs files (it says "device or resource busy" if I
try to delete them) and the only way I can do another parametric sweep
is to quit and restart icfb. I see online that other people have the
same problem, but I haven't been able to find a solution. Does anyone
know a way around this problem?

Thank you very much in advance,
Andrew

 

Hi Andrew,
This issue is seen specifically with RHEL4.0 as IC5141 and IC5033 is
not yet fully supported on RH4.0 by Cadence R&D.
Make sure that your simulation directory (~/simulation this is default)
is mounted on NFS. if thts not the case.
Then the workaround is to go to menu -> Setup ->
Simulator/Directory/Host and switch to another project directory. say
simulation1 etc..
Or grep the incomplete spectre processes and kill it manually.

I hope the above info helps.

Thanks,
Rti

 

Thank you BEE and Rti very much for your help! Yes we are running
CentOS4.3, so that would be the problem. I will try your suggestions.

Actually, just last night I found another workaround, since another
forum suggested it might be the connection between the program running
on the local machine and our remote fileserver. This is along the same
line as what Rti suggested.

1. Create a temporary directory on the local machine you are using.
In the terminal window, go to /tmp directory and create a directory for
yourself to store your cadence sim data, called "yourusername-sim"

2. Open cadence as normal, except when you use analog design
environment, go to Setup --> Simulator/Directory/Host... and in the
Project Directory, type "/tmp/yourusername-sim"

3. You might need to reload your analog design environment state.

With this setup, we use the /tmp/yourusername-sim directory instead, so
cadence doesn't have to communicate with the fileserver for parametric
analysis sim data writing. Note that the simulation data stored in the
/tmp directory will not be accessible if you switch to another server.
