LogiCORE SPI-3 LINK Layer Core v4.0 - Bitgen gives ERROR:PhysDesignRules:755 - IOB comp <TX_DTPA(16)> at location <AH34> is VCCO (also applies to SPI-3 PHY Layer)

Description

General Description:

When running design with SPI-3, you might receive the following Bitgen error:

Solution

This occurs for both SPI PHY and SPI Link using ISE7.1i. It occurs for VCCO = 3.3V and 2.5V both in the same design.

This error does not occur using ISE8.1i.
