abutment to connect different bit slices, and over-the-cell routing for connecting different units inside one bit slice. Different strips for P and N transistors are laid out horizontally. Data signals run vertically in second metal over the bit slices. Power, ground, and control lines are routed in first metal or poly between the bit slices.

One of the synthesis problems in cell generation is transistor folding, which consists of breaking large transistors into smaller ones (legs) that can be placed in the active area of the cell.

Transistor abutment

Consequently, it is the most important factor to be considered. There are two essential conditions for two transistors A and B to be abutted: on the abutment of transistors. Abutment reduces transistor source/drain diffusion area and hence cell-width by merging same diffusion nets of adjacent transistors [2]. However maximal abutment does not always assure the best layout for routing intensive cells and may even result in unroutable or routing congested solution, causing Other things to be considered are: power structure, number and direction of the metal layers available for intracell routing, gridded design rules (GDRs), abutment scheme, position of the routing tracks, isolation transistors, multigate transistors, standard cell compatibility, regular layout fabric (prefabricated), TAPs, etc. rows for the placement of P and N transistors.

merging, abutment and alignment technique simultaneously. Two cell (MTIP3&IP3) are used to demonstrate the effectiveness of approach. Moreover, the proposed method generates more area-efficient transistor placements than the conventional method. In experiment we applied PN and PNN pattern for placement of devices with the device
