Abstract
A method for simulating signal integrity of a hybrid model is provided, which includes: establishing a transient simulation link including a front-end chip model, a pre-link model and a terminating impedance model, where the front-end chip model is a Spice model; inputting an ideal step signal to a port reserved in the front-end chip model, and extracting step response data in a steady state; inputting the step response data to an input end of a channel simulation link, where the channel simulation link includes a relay chip model, a post-link model and a back-end chip model, and each of the relay chip model and the back-end chip model is an IBIS AMI model; and inputting a random code signal to the input end of the channel simulation link, and reading a signal outputted from an output end of the back-end chip and forming an eye pattern.
