ADIsimRF™: Provides calculations for the most important parameters within the RF signal chain, including cascaded gain, noise figure, IP3, P1dB, and total power consumption

ADIsimPLL™: Enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL synthesizer design and simulation tool available today. Simulations performed include all key nonlinear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design to market.

ADIsimSRD™ Design Studio: Enables real-time simulation and optimization of many of the parameters in a typical wireless system using the ADF7xxx family of short range transceivers and transmitters. The tool allows users to view modulation in both the time and frequency domains

ADIsimCLK™: Allows designers to work at a higher level and directly modify parameters such as the loop bandwidth, divide ratios, phase offsets, and output frequencies—and the effects of the changes on performance are shown instantly.

ADIsimADC™: Accurately models the typical performance characteristics of many of our high speed converters. The model faithfully reproduces the errors associated with both static and dynamic features such as AC linearity, clock jitter, and many other product specific anomalies.
