Hi,

Reducing simulation time will solve the negative dv/dt problem.

Subject: [IBIS] problem with dv/dt

Hi ,

  I am using s2ibis2 for solaris.

 While generating the curves, i find a problem with the [Rising
Waveform] and [Falling waveform]

 The dv/dt_r gives me values like 0.15/-40.000p.
 And the dv/dt_f also gives me 0.15/-40.000p.

 What can be the potential cause of the problem ?

  Also i dont seem to undersand the some concepts behind the generation
of the IBIS models. Can anyone suggest me any material/text book/link
which can help me with a complete theory of the IBIS model generation
process ?

 I have downloaded s2ibis2 for solaris from the website. Does the source
code need any modifications before i use them for real test cases ?

Any help will be appreciated.

Thx,
Vivek
