The FCC-ee is a proposed future $e^+e^-$ collider aimed at producing an unparalleled number of Higgs, $Z$, and $W$ bosons, as well as of top quarks, in very clean experimental conditions. Numerous measurements at the FCC-ee rely on a precise and accurate measurement of the location of the primary and secondary vertices.

This work presents the implementation of the IDEA vertex detector in full simulation using the Key4hep and DD4hep frameworks widely used by the future collider communities. The IDEA vertex detector is represented in DD4hep in great detail, using the correct stack of materials for the support, cooling and readout structures. The silicon sensors are described as multiple sensitive and insensitive volumes, properly representing the sensor layout. The material budget is evaluated to be $\approx 1/3\%\ X_0$ per inner vertex layer at normal impact, which aligns with the assumed material budget in the FCC conceptual design report. Soon, the complete IDEA detector will be available in full simulation, allowing the evaluation of the detector concept realistically.
