Creating Corners in maestro using SKILL

KGh94

Hello,

I was looking in the maestro documentation for a command to create a corner in my test. I couldn't find creation, but rather only enabling/disabling:

maeSetSetup(?corners '("C0" "C1") ?variables '("VDD" "IREF")?enabled nil)
; Disables the C0 and C1 corners, and the VDD and IREF global variables

Is there a way to create a corner in maestro using SKILL?

Best regards,
Karam

  • Hi Karam,

    You have to use the axl functions to create the corners; there's no specific "mae" functions to do it (there's the ability to load the corners from a file, but not to define them from scratch). It's perfectly OK to use the axl functions to do this though.

    Regards,

    Andrew.

    Hello Andrew,

    Thank you for the confirmation. I noticed that it's not possible to disable nominal corner in maestro:

    ; check active corners
    maeGetSetup(?typeName "corners" ?enabled t)    => ("nominal" "myCorner")

    ; disable nominal corner
    maeSetSetup(?corners '("nominal") ?enabled nil)

    I get the message:

    WARNING (ASSEMBLER-8047): Failed to disabled corner nominal because it does not exist in the currently active setup. Specify a valid corner name. Use maeGetSetup(?corners) to get list of corners available in this session.

    I would also point out that the underlined command is incorrect and would return an error..

    Is there a work-around for disabling the nominal corner?

    Best regards,
    Karam

    Hi Karam,

    It's a limitation of the API, and is covered by CCR 1920347. Hopefully we can fix this before too long as well.

    The workaround is to use:

    sess=maeOpenSetup(...) ; make sure you record the session when you start with maeOpenSetup
    ; could also use sess=axlGetWindowSession() if running interactively
    sdb=axlGetMainSetupDB(sess)
    axlSetNominalCornerEnabled(sdb 0)

    This will disable it. Set the second argument to 1 to enable the nominal corner.

    Regards,

    Andrew.
