Simulation models for HMC699 (PLL) with HMC583 (VCO)

I need to design a 12-13 GHz low-noise frequency synthesizer based on the HMC699# PLL# and the HMC583# VCO#.

Is it possible to have their models to simulate this system with Hittite's design tool v1.15 that I have downloaded from your site?

By the way, when do you plan to integrate all Hittite's frequency synthesis products into ADIsimPLL#?

Thank you veru much in advance, and best regards.
