How to accelerate the simulation with the Transceiver HSPICE model

--- Quote Start ---

So when i find the simulation takes a long time with a low frequency signal, i think it's because i don't use this model correctly.

And you are correct. The simulation is for designing high-speed signals. The time required to simulate multiple bit transitions of a Gbps signal is significantly shorter than that required to calculate kbps signals ... a million times faster ....

By the way, do you konw where i can find a DP cable model as IBIS/S-parameters/Spice ?

Try vendor web sites, eg., Tyco, Molex, etc., or contact a distributor FAE and ask.
