I have a Problem when using in the same project a model "ibis" and a "Spice" model in the hyperlynx boardsim simiulation. see scrennshot attached :
Thank you very much for your help,
Actually, the problem is not caused by using an IBIS model, but by using a .MOD model. Here is a chart that shows what model types you can use in the different simulation engines available in HyperLynx.
You should replace the .MOD model with a similar IBIS model. Then you can run the simulation in Eldo/ADMS.
Thank you it work. But the simulation take a very importatnt time ( see attached).
Are a solution or recomandation to solve this problem ?
very very long time :
Engineering is a series of trade-offs. This is the disadvantage of using transistor level SPICE models for simulation. They simply take longer to simulate because of the increased number of nodes and the more complex equations that must be calculated for every iteration. That is one of the major reasons the IBIS committee created the AMI section of the specification. AMI models generally run much faster than transistor level SPICE models.
the problem that there is no ibis model for cable and connectors ... there are only Spice / Touchstone model ...
Retrieving data ...
