Multiple asynchronous ADEXL simulations using SKILL

Rather than waiting for the simulation to finish, the way to do this is to use the ?callback argument of axlRunSimulation. This will then call a function when the simulations have finished, and then that callback can be used to do all your results processing.

Kind Regards,

Andrew.

Hey Andrew, Thanks for your help. I tried the way you mentioned me but I am stuck when I run multiple simulations. Let me share my whole code here

axl_session=axlCreateSession(getCurrentTime())

hsdb=axlSetMainSetupDBLCV(axl_session libName cell "adexl" ?mode "r")
tests=axlGetTests(hsdb)
;; Get enabled tests
test_names=setof( test
cadr(tests)
axlGetEnabled( axlGetTest( hsdb test )));setof

;; Run simulation
printf("[INFORMATION]:\t\t RUNNING SIMULATION\n")
simId = axlRunSimulation(?session axl_session ?callback "compile(axl_session simId)")

/***************************************************************
* RESULTS COMPILATION *
***************************************************************/
procedure(compile(axl_session simId)

printf("[INFORMATION]:\t\t SIMULATION COMPLETED. NOW COMPILING RESULTS\n")
history = axlGetRunData(axl_session simId)
rdbPath = axlGetHistoryResults(history)
rdb = axlReadResDB(rdbPath)
;; HELP COMMAND FOR RESULTS
;; axlReadResDB

;; Extract results
foreach(point rdb->points()
printf("Point %d\n" point->id)
foreach(corner point->corners()
printf(" Corner %L\n" corner->name)
foreach(test corner->tests()
printf(" Test %L\n" test->name)
foreach(output test->outputs()
when(output->type=='expr
; take your pick
;printf(" Output %s = %s\n" output->name output->valueAsString())
printf(" Output %s = %L\n" output->name output->value)
)
)
)
)
)

);procedure

This code reads the user file for library and cell name and then open each cell adexl view, run the simulation for the test and then open the results database and show the simulation results. The problem is when I run 2 simulations and my simId variable value is same for both simulations (i.e. simId = 0) which causes an error while opening the results database. for first simulation run I get this 

INFORMATION]: SIMULATION COMPLETED. NOW COMPILING RESULTS
*WARNING* argument must be a fixnum, flonum, complex, or strnum
Point 1
Corner "nominal"
Test "test:pmos:1"

and for the next simulation I get this output

[INFORMATION]: SIMULATION COMPLETED. NOW COMPILING RESULTS
Point 1
Corner "nominal"
Test "test:pmos:1"
Output ID (DC) = 0.0002861345

the second output is correct but first output is wrong. I guess the due to same simId its targeting the different results database. any hint how could I solve this issue

I won't be able to look at this until later (possibly tomorrow) because I'm just about to leave the office for a meeting. However, in the meantime can you let me know which subversion of Virtuoso you're using (Help->About)?

Thanks,

Andrew.

Hey Andrew,

did you get a chance to look into it ?. I figured out that "axl_session" variable gets updated for each run and when any simulation finishes it uses the current value of axl_session to browse the results database, rather then the value that was used for callback.
