When I am using APS for PSS (shooting Method) using swap file, APS is being disbled.
How can prevent APS being disabled.
Are you invoking APS in your ocean script? Specifically, have you included a line such as:
envOption( 'userCmdLineOption "+lqt 0 +lqtimeout 0 -64 +aps")
This line invokes aps (+aps) as well as uses a 64 bit binary and waits indefinitely for a spectre license to be available. I have not experienced an issue invoking aps in a PSS simulation.
