Problems to delete simulation results under Cadence Analog D

Hello,

I have problems to delete simulation results under

Cadence Analog Design Environement (IC5.0)

When I try to use the menu command

results->delete

and I choose a simulation directory I get the following errors



*Error* Could not determine the simulator from data dir
/opt/sim/simulation/VCO1_PHN_SIM_pA1/spectre/schematic/distributed/040730resonant26p.

*Error* Could not delete results from
/opt/sim/simulation/VCO1_PHN_SIM_pA1/spectre/schematic/distributed/040730resonant26p




Did anybody have the same problems?


Thanks for any advice

Hi Carl

If U r using unix enviorment do this
at unix prompt
unalias rm
rm -r simulation
Click to expand...

it will remove ur simulation results.
simulation directory is created again when u do simulation.

Also make sure ur simulation tool like verilog -XL or analog
enviornment is closed. and ur not using simulation data anywhere else
..
once u close these u should be able to delete the data using above
commands

Carl:
I see the same. Looks like a bug to me. Don't know why Cadence can't do a:
system("\\rm -rf path")

Erik,

Doing an rm -rf wouldn't help. The problem is that an application (spectre in
this case) still has a file open, and so if the directory is on an nfs mounted
disk, nfs makes sure there is still a means of accessing the file even if the
main filename has been deleted (the nfs equivalent of an inode). So you'd
see a .nfsXXX file appearing.

I suspect that if you did Simulation->Stop or exited the ADE window, you'd
be able to delete with no problem.

The root cause is understood, and the fix is understood (I think) - it just
needs scheduling amongst all the other priorities.

Andrew.

Andrew:
I don't think this error has to do with a directory where a file can't
be deleted (.nfs...). The error is:
*Error* Could not determine the simulator from data dir

Why does it need to know the simulator to delete a directory?

I had no problem doing a system("\\rm -rf path") on the results
directory with ADE still open just after Simulation->Results->Delete
failed.

From reading the PCR, it appears to be related to the .nfs file in some cases...

Sorry, don't have time to experiment more right now.
