Adding ADE Analysis using SKILL code

 I want setup transitent analysis for 1u stop vlaue using SKILL code ) . I was trying to that using asiGetAnalysis and asiAddAnalysisField or asiAddAnalysisFieldVal. 

It would be really helpful if you could kindly give me an example SKILL code that does the following :

1) set the simulator to "spectre"

2) setup transient analysis for 1u

In docementation I have found this asiSetFormFieldVal( r_form  ?stop "5n" ). How do get the r_form handle for analysis. 

Thanks
