OKI SEMICONDUCTOR
- Add together all the area occupied by the required random logic and macrocells and select
the optimum array.
2. Make a floor plan for the design’s megacells.
- OKI Design Center engineers verify the master slice and review simulation.
- OKI Design Center engineers floorplan the array using OKI’s proprietary floorplanner and
customer performance specifications.
- Using OKI CAD software, Design Center engineers remove the SOG transistors and replace
them with diffused memory macrocells to the customer’s specifications.
Figure 2
shows an array base after placement of the optimized memory macrocells.

3. Place and route logic into the array transistors.
- OKI Design Center engineers use layout software and customer performance specifications
to connect the random logic and optimized memory macrocells.
Figure 3
marks the area in which placement and routing is performed with light shading.
