ADEXL Test Setup using Skill and asiGetSession Failure

Curtisma

I'm trying to setup an adexl cellview with a single test.  However everytime I load the script shown below the asiGetSession on line 7 often returns nil and its not clear why that is the case.  Any ideas as to what is causing it to fail to get the session?  Is there a better way to setup the state of that test using SKILL (not ocean)?

ddGetObj("pk1126_sky77366_5_CR_mayberc" "pk1126_01_TB" "adexl" "data.sdb" nil "w")
sessionName = strcat("mysession" (sprintf nil "%d" random()))
axlSession = axlCreateSession(sessionName)
sdb = axlSetMainSetupDBLCV( axlSession "pk1126_sky77366_5_CR_mayberc" "pk1126_01_TB" "adexl")

;---------- Test "IDAC_SWEEP_MAIN" -------------
testSession = asiGetSession( 'IDAC_SWEEP_MAIN )
dc_analysis = asiGetAnalysis(testSession, 'dc)
asiSaveState(testSession ?name "IDAC_SWEEP_MAIN" ?option 'dir ?stateDir "/prj/pk1126_sky77366_5_CR/work_libs/mayberc/cds/design/pk1126_01_TB/adexl/test_states" ?description "IDAC_SWEEP_MAIN" )
htest = axlPutTest( sdb "IDAC_SWEEP_MAIN" "ADE")
axlSetTestToolArgs( htest list( list("lib" "pk1126_sky77366_5_CR_mayberc") list("cell" "pk1126_01_TB") list("view" "config") list("path" "/prj/pk1126_sky77366_5_CR/work_libs/mayberc/cds/design/pk1126_01_TB/adexl/test_states") list("state" "IDAC_SWEEP_MAIN_active") list("sim" "spectre")))

;====================== Save Setup ============================================
axlSaveSetup(axlSession)
axlCommitSetupDB( sdb )
axlCloseSetupDB( sdb )

  • I rearranged it so that the test is created in adexl session first to define 'IDAC_SWEEP_MAIN. However now I can't seem to save the ADE L session. The call to asiSaveState gives the error below.  I have tried several paths to save the ADE L State and all of them give the same error.  Any ideas about what is causing the error?  Is there a better way to point the test to the ADE L state?


    Updated Script:

    ddGetObj("pk1126_sky77366_5_CR_mayberc" "pk1126_01_TB" "adexl" "data.sdb" nil "w")
    sessionName = strcat("mysession" (sprintf nil "%d" random()))
    axlSession = axlCreateSession(sessionName)
    sdb = axlSetMainSetupDBLCV( axlSession "pk1126_sky77366_5_CR_mayberc" "pk1126_01_TB" "adexl")

    ;---------- Test "IDAC_SWEEP_MAIN" -------------

    htest = axlPutTest( sdb "IDAC_SWEEP_MAIN" "ADE")
    testSession = asiGetSession( 'IDAC_SWEEP_MAIN )
    dc_analysis = asiGetAnalysis(testSession, 'dc)
    ;asiSaveState(testSession ?name "IDAC_SWEEP_MAIN" ?option 'dir ?stateDir "/prj/pk1126_sky77366_5_CR/work_libs/mayberc/cds/design/pk1126_01_TB/adexl/test_states" ?description "IDAC_SWEEP_MAIN" )
    asiSaveState(testSession ?name "IDAC_SWEEP_MAIN" ?option 'dir ?stateDir "/prj/pk1126_sky77366_5_CR/doc/pk1126_01_TB/adexl/test_states" ?simulator "spectre" ?description "IDAC_SWEEP_MAIN" )

    axlSetTestToolArgs( htest list( list("lib" "pk1126_sky77366_5_CR_mayberc") list("cell" "pk1126_01_TB") list("view" "config") list("path" "/prj/pk1126_sky77366_5_CR/doc/pk1126_01_TB/adexl/test_states") list("state" "IDAC_SWEEP_MAIN_active") list("sim" "spectre")))

    ;====================== Save Setup ============================================
    axlSaveSetup(axlSession)
    axlCommitSetupDB( sdb )
    axlCloseSetupDB( sdb )


    Error:

    *Error* Could not create directory: /results.

    *Error* Could not create directory: /results.

  • You're doing this the wrong way. You should look at this solution which gives an example of how to do this.

    It doesn't make sense to do asiGetSession() that way and then asiSaveState - what you should be doing is putting the test, and then something like this:

    testName="IDAC_SWEEP_MAIN"
    htest = axlPutTest( sdb testName "ADE")
    axlSetTestToolArgs(htest list( list("lib" libName) list("cell" cellName) list("view" "schematic") list("sim" "spectre")))
    testsess=axlGetToolSession(axlSession testName)
    testSession=asiGetSession(testsess)

    (I tend to use sevEnvironment(testsess) for the last bit, but I don't think it matters).

    Then having got that you can do whatever you need to the test session, no need to save state or anything like that.

    Regards,

    Andrew.

  • Thanks Andrew!

    Here is my updated code that seems to work great for setting up this test. Do you see any issues with it?

  • Andrew:

    How do I use skill to change the Save All... options. Specifically I want to set it so that it only saves selected voltage and current nodes rather than saving all voltages.

    -Curtis

  • Curtis - yes, this looks reasonable!

    Ah, just seen your last question. That's easy enough:

    asiSetKeepOptionVal(testSession 'save "selected")
    asiSetKeepOptionVal(testSession 'currents "selected")

    Regards,

    Andrew.
