Corners simulation by ocean script

[jugemu1234]

Hi,

I have been trying corners simulation with several kinds of parameter
change via ocean script. Pls see following script detail. I run it
via CIW.
Problem is, though I specified different resultsDir for each
cornerRun, "Corners" folder just below the "schematic" folder is
overwritten all the time. Would anybody know how I can prevent this?

Thanks in advance.

desVar( "trim7" 0 )

loadPcf("/MydfII/corners7.pcf")

cornerRun()
cornerMeas()

resultsDir( "/MydfII/simulation/sim_osc2/spectre/schematic/org10" )
desVar( "trim7" 1 )
desVar( "trim0to6" 0 )
cornerRun()
cornerMeas()

resultsDir( "/MydfII/simulation/sim_osc2/spectre/schematic/org01" )
desVar( "trim7" 0 )
desVar( "trim0to6" 1 )
cornerRun()

I think you need to introduce an additional directory level in there. The
corners stuff (if my memory is correct) will put the results in alongside the
"results" directory.

I'm afraid I don't have time at the moment to experiment to check.
