Any inputs will be appreciated. >=20 >=20 Some things to check: Is the B-element connected correctly? Are you using the right B-element node for connection to the rest of your circuit? What is the load? Double-check the units in the IBIS datasheet file ("model"). Is the risetime the only difference, or are the initial and final voltage levels wrong too?
