RE: [IBIS-Users] How I can extract two value for vinh and vinl

Hello, Akilesh,

These values normally come from the interconnect specification.  If there
are no parameters equivalent to Vinh+, Vinh-, Vinl+ & Vinl-, then these
parameters are not used in the IBIS model.

If you are not following an external specification, then you need to do a
complete PVT (process, voltage, temperature) analysis for Vinh and Vinl (not
just one corner).

Hi,

     I have just one query. According to the IBIS specification we can
support Vinh+, Vinh-, Vinl+ & Vinl-.

   I extract these valuse by applying one pulse at the input and find out
the voltage at which it switch from 0->1 and 1->0. According to me I have
only one value at one process, voltage temp. How I can extract two value for
vinh and vinl for one process, voltage and temp.

Regards
Akhilesh
