vant timing parameters of the device. It is not intended to be either a precise representa-
tion of the typical system environment or a depiction of the actual load presented by a
production tester. System designers will use IBIS or other simulation tools to correlate
the timing reference load to system environment. Specifications are correlated to produc-
tion test conditions (generally a coaxial transmission line terminated at the tester elec-
tronics). For the half-strength driver with a nominal 10pF load, parameters
are expected to be in the same range. However, these parameters are not subject to
production test but are estimated by design/characterization. Use of IBIS or other simula-
tion tools for system design validation is suggested.
