摘要： The present invention is directed to methods for disabling unused IO resources in a platform-based integrated circuit. A slice is received from a vendor. The slice includes an IO circuit unused by a customer. The IO circuit is disabled. For example, when the IO circuit is desired to be tied to a power source, a primary input/output pin of the IO circuit is shorted to a power bus of the IO circuit. When the IO circuit is desired to be tied to a ground source, a primary input/output pin of the IO circuit is shorted to a ground bus of the IO circuit. When the IO circuit is desired to be left floated, a primary input/output pin of the IO circuit is not connected to any bonding pad cell of the slice. Next, the IO circuit is removed from the customer's logic design netlist. The IO circuit is inserted in the vendor's physical design database.

摘要翻译： 本发明涉及用于在基于平台的集成电路中禁用未使用的IO资源的方法。 从供应商接收到一个切片。 该片包括客户未使用的IO电路。 IO电路被禁止。 例如，当IO电路需要连接到电源时，IO电路的主输入/输出引脚与IO电路的电源总线短路。 当IO电路需要连接到接地源时，IO电路的主输入/输出引脚短接到IO电路的接地总线。 当IO电路需要悬浮时，IO电路的主输入/输出引脚不连接到片的任何焊盘单元。 接下来，IO电路从客户的逻辑设计网表中删除。 IO电路插入供应商的物理设计数据库。

摘要： The present invention provides a system for implementing a configurable integrated circuit (IC). Aspects of the invention include an IC die; a plurality of input/outputs (I/Os) coupled to the IC die; and a plurality power planes coupled to the IC die for providing power to the plurality of I/Os at different voltages. The plurality of power planes are configured concentrically around the IC die so that any one or more of the I/Os at any location on the IC die can be individually configured to connect to any of the power planes. As a result, any number of I/Os available on the IC die can operate at a given voltage.
