I am using IC615 and MMSIM 111  and here i am now add my error screen shots, so please give me any ideas to solve the error.

  • The waveforms look the same in the psf you uploaded. What would have been more useful is if you showed the actual expression you used - the psf doesn't (and wouldn't) contain the expression.

    I took your new data and used:

    delay(?wf1 v("a" ?result "tran"), ?value1 0.2, ?edge1 "either", ?nth1 1, ?td1 0.0, ?wf2 v("z" ?result "tran"), ?value2 0.9, ?edge2 "either", ?nth2 1,  ?td2 nil , ?stop nil, ?multiple nil)

    in the calculator, and it worked fine. Please paste your expression rather than showing a screenshot - that way I can paste it into the calculator and check.

    Which subversion of IC615 are you using? Help->About in the CIW will tell you, or type getVersion(t) in the CIW.

    Regards,

    Andrew.
