With the extensive application of stretchable flexible electronic circuits to wearable equipment and biomedicine, research on the electrical properties of such circuits has become a hot topic. In this paper, a flexible electronic design platform is established for the first time, realizing co-simulation of the mechanical and electronic aspects. The main functions of this platform include the design of stretchable interconnects, flexible devices, stretchable flexible electronic circuits, and stretchable flexible circuit-layout wiring. The following conclusions can be obtained: (1) With increased applied strain, the inductance of a stretchable interconnect will increase, while the delay and crosstalk will become non-negligible. (2) Although the performance of flexible passive devices does not change after transfer printing, the gate capacitor of the flexible MOS at the cut-off area does decrease. (3) Taking a flexible comparator as an example, the function and electrical performance of a flexible circuit are verified. (4) Taking a flexible amplifier circuit as an example, the flexible interconnection layout and wiring are simulated and verified.
