Uni-gate cell design

A non-transitory computer-readable medium including computer-executable program for, when being executed by a processor, implementing a method, comprising:

• receiving a circuit diagram that includes a first active device and a second active device;
• determining a first active cell structure for the first active device, a first transitional cell structure for a first transitional device associated with the first active cell structure, a second active cell structure for the second active device, and a second transitional cell structure for a second transitional device associated with the second active cell structure, wherein each of the first active cell structure, the first transitional cell structure, the second active cell structure, and the second transitional cell structure comprises a plurality of uni-gates having a common uni-gate length and a cumulative effective gate length of the plurality of uni-gates is equal to a gate length of each of the first active device, the first transitional device, the second active device, and the second transitional device;
• generating, based on the first and second active cell structures, the first and second transitional cell structures, and the first and second active devices, a floor plan that comprises an arrangement of a plurality of placeholders that match an arrangement of the first and second active cell structures and an arrangement of the first and second active devices in the circuit diagram;
• and
• generating a circuit layout based on the floor plan, the first and second active cell structures, the first and second transitional cell structures, and the circuit diagram, wherein the plurality of placeholders are replaced by the first and second active cell structures and the first and second transitional cell structures, the first and second transitional cell structures abut each other and separate the first and second active cell structures, and the first and second active cell structures are connectable to other parts of the circuit diagram based on the circuit diagram.
