Extended Data Fig. 1

The figure shows the evolution of the standard cell library from left to right. It starts with a 1-μm channel length library, and then moves to an 0.8 μm channel length with different sheet resistances. The far right panel shows the final library that is used to implement the PlasticARM FlexIC. VDD, supply voltage; VSS, ground; CONT, electrical contact between the source–drain layer and the next metal layer; VIA, electrical contact between routing layers.
