Hi Experts,
I am facing a problem with MPC8264 IBIS model. When i tried to
convert the IBIS model into dml format, the IBIS2SIGNOISE gives the
following error message.
" TVCurve must start at time zero "
I faced a similar problem with MPC8260 and still i could not get a solution
for that. I am not good in IBIS modelling. So i couldn't solve this. If
somebody had ever faced this kind of problem and have solution, please help
me to get the solution.
thanks and regards,
Siva
Note : I have copied the output of IBIS2SIGNOISE utility for your reference.
