How could i get a Plot with a Xaxis in volt by the ocean script?

 EDIT NOTES

 
The monteCarlo simulation works (successful)!!
 but just there are these lines of error concerning "the evaluating ocean monteExpr".

 Come one Mr Olyonnais! You forget a double quote of the delay. Check your expression syntax.

 monteExpr( "Delay_WL_S_rise" "delay(clip(v(\"/WL\" ?result \"tran-tran\")" 

Check your expression step by step when your not sure.

So are you Lyonnais or Niçois ?

Axel,

In the psf directory, you should find a file artil.log which may well reveal the cause of the error - any error messages will be shown there.

Best Regards,

Andrew.

 Hi eBecheto

I think you have not the entire expression because i didn't forget anything....

monteExpr( "Delay_WL_S_rise" "delay(clip(v(\"/WL\" ?result \"tran-tran\") 2.871401e-08 3.685221e-08) VAR(\"Vdd_half\") 1 \"either\" clip(v(\"/S\" ?result \"tran-tran\") 2.871401e-08 3.685221e-08) 0.55 1 \"either\" 0 0 nil nil)" )

 The problem that i have, is that my monteCarlo analysis is successful but i obtain an error on the evaluation of the monteExpr.

ps: I'm lyonnais ;) but living in Nice.

 Andrew,

 here the artil.log with a montecarlo of 2 runs

I checked that the desVar is saved in the variables_File:

"Vdd_half" "variable" ( 550e-3 ) PROP( )

Hi Axel,

Try changing the "tran-tran" in your expression to "tran" or 'tran :

monteExpr( "Delay_WL_S_rise" "delay(clip(v(\"/WL\" ?result 'tran") 2.871401e-08 3.685221e-08) VAR(\"Vdd_half\") 1 \"either\" clip(v(\"/S\" ?result 'tran) 2.871401e-08 3.685221e-08) 0.55 1 \"either\" 0 0 nil nil)" )

It's best to use the "aliased" names (this is covered in the "Advanced Analysis" manual in the IC release, if my memory is correct).

Regards,

Andrew.

 Andrew,

Thank you again you solved my problem...

I change the "tran-tran" in your expression to 'tran : before i corrected the little mistake here: 'tran"

monteExpr( "Delay_WL_S_rise" "delay(clip(v(\"/WL\" ?result 'tran") 2.871401e-08 3.685221e-08) VAR(\"Vdd_half\") 1 \"either\" clip(v(\"/S\" ?result 'tran) 2.871401e-08 3.685221e-08) 0.55 1 \"either\" 0 0 nil nil)" )

 So i put 'tran and now its perfect !!

Could you explain me the difference between "tran" and "tran tran " ? please

thank you again Andrew.

Axel

Hi Axel,

Apologies for my typo - meant to omit the final quote, of course.

If you have a look in <ICinstDir>/doc/aatoolsuser/aatoolsuser.pdf and search for "Data Name Aliasing" you'll find a section which describes. There are some following sections which also describe creating expressions compatible with monte carlo.

The problem with using tran-tran is that this can result in picking (say) the nominal results rather than the result from each monte carlo point. The benefit of the "aliased" name (i.e 'tran or "tran") is that it will always pick the current point's run (even though it may be actually called "mc1_tran-montecarlo" or something like that).

Hope that helps!

Regards,

Andrew.

Axel,

Are you sure? It should work with either 'tran or "tran" (of course in the monteExpr it would have to be \"tran\" because the string is within quotes already). Of course it wouldn't have worked with 'tran" because that was me making a silly mistake.

Inside the code, it will treat a symbol or string the same, as far as I know (for this situation).

I just tried my example with v(\"/net5\" ?result \"tran\") and it worked with no problems.

Regards,

Andrew.
