[SI-LIST] IBIS Models for the Devices working at GHz speed

Hello SI Experts,
   
  I have seen that for the devices working at GHz speed (for Example Vertex 
FPGA) vendors generally prefer to provide encrypted Spice model and not IBIS 
models. Are there any limitations of IBIS model at higher speed? Thanks!
   
  Regards,
  Darshan Mehta
