This paper discusses the importance of chip-level EM-simulations required at millimetre wave frequencies for achieving correct results. The negative impact of interconnects on passive structures and the inability of the conventional RC-extraction to cater their effects necessitate alternative solutions. Furthermore during IC-measurements the number of probing points is limited; therefore chip-level simulations can provide insight into circuit behaviour at any point in the circuit. In this work, a non-oscillating 60 GHz transformer coupled I-Q VCO is used as a test-case and it is proved that carrying out EM-simulations for the complete circuit can provide valuable information during the design phase. Sonnet® and Advanced Design Systems® are utilized for EM-simulations and postprocessing functions, respectively.
