does not pass through an inverter, so that the input can remain unconnected. Rewired the existing implementation to use an alternative gate that has an inverting input so that the user_gpio_out signal can be left undriven when the GPIOs are in the management enable state. This is a simple logic refactoring and does not change the logic function. The manual rewiring has been confirmed by LVS, but at least one GL simulation should be run to confirm that the logic function remains the same as before. |
