Automation in Calculator

Hi Andrew, 

When I am using this fucntion as, 

axlAddOutputExpr("session11" "tb_usr1_clk:tb_driver_1440um_singleroute:2" "ttttdsfdt" ?expr "riseTime(clipX(v("/CLKP_120u" ?result "tran") 863.6E-12 5.0E-9 ) 0 nil VAR("supply") nil 10 90 nil "time" )")

Its giving syntax error pointing at the ?result part. I have used this expression from calculator which is able to correctly evaluate this. The thing is the function should directly take whatever is in "" as string and should be able to put it in adexl.
So I tried this,
axlAddOutputExpr("session11" "tb_usr1_clk:tb_driver_1440um_singleroute:2" "ttttdsfdt" ?expr "abd")

And it passed whereas "abd" didnt even mean anything.
Why is this error then coming in the upper use case. How can I forcefully impose something as string?

It's because the string contains quotation marks - and so the string will end as soon as the first quotation mark it finds within the sequence of characters unless you escape them. So you'd need to do:

axlAddOutputExpr("session11" "tb_usr1_clk:tb_driver_1440um_singleroute:2" "ttttdsfdt" ?expr "riseTime(clipX(v(\"/CLKP_120u\" ?result \"tran\") 863.6E-12 5.0E-9 ) 0 nil VAR(\"supply\") nil 10 90 nil \"time\" )")

You'd need to do the same if using the function I provided you with above:

CCFaddManyExpr("tb_usr1_clk:tb_driver_1440um_singleroute:2" "riseTime(clipX(v(\"/%s\" ?result \"tran\") 863.6E-12 5.0E-9 ) 0 nil VAR(\"supply\") nil 10 90 nil \"time\" )" ?outNameTemplate "rt %s")

So all embedded quotation marks need to be prefixed by backslash to escape them so that they are not interpreted as the end of the string (or the start of another one).

Hi Andrew,

Is there a function by which I can add spec(range or less than or greater than a value etc) to each of the measurements?

Thanks

Hi Sheenu,

Yes, that would be axlAddSpecToOutput() . If you were using Explorer/Assembler, there's a simpler interface using maeSetSpec().

Hi Andrew,

Hi Sheenu,

If you're asking how to do this in general for a string, then it would be:

when(index(theString "risetime")
   ; do what you want when it matches
)

or using regular expressions:

when(pcreMatchp("risetime" theString)
   ; do what you want when it matches
)

The benefit of pcreMatchp is that you then can have full regular expressions - so it could be "^risetime.*" which would mean anything beginning with risetime followed by any number of any character; strictly speaking the pattern doesn't need to be "anchored" though - so the trailing ".*" isn't really needed here.

Hi Andrew,

In this following code, this error is coming,"pcreMatchp: argument #2 should be either string or a symbol"

axlSess=axlGetWindowSession() ;To get active adexl session
sdb=axlGetMainSetupDB(axlSess)

foreach(testName cadr(axlGetTests(sdb))
sevSess=axlGetToolSession(axlSess testName)
asiSess=sevEnvironment(sevSess)
foreach(output asiGetOutputList(asiSess)
outname=output->name
when(pcreMatchp("Risetime" outname)
printf(" %s : %L\n" output->name output->expression))

)
)

I am not able to figure out why this is occuring.

If you have any outputs which don't have a name, then output->name will be nil (this could be signals). So you should do:

when(outname && pcreMatchp("Risetime" outname)
  printf(" %s : %L\n" output->name output->expression))
)

You could also use:

foreach(nameExpr sevGetExpressions(sevSess ?namedOnly t)
  when(pcreMatchp("Risetime" car(nameExpr))
    printf(" %s : %s\n" car(nameExpr) cadr(nameExpr))
  )
)

Note that when using sevGetExpressions it returns a list of lists, with the first element being the name, and the second being the expression (as a string).

Oh I got it Andrew, thank u. It was "nil" which was creating issue!
