INTERFACE CIRCUIT FOR FULLCUSTOM AND SEMICUSTOM CLOCK DOMAINS

摘要

The inventive integrated circuit has an interface circuit between the anolog circuit part (FC, or "full-custom") and the digital circuit part (SC, or "semi-custom") for each signal to be exchanged. Said interface circuits are assembled in a central block of interfaces. In this way, line lengths and loads are predetermined, making the dimensioning of the gates and their drivers more simple and ensuring an exact timing simulation of the semi-custom part. Improved embodiments relate to the application of predetermined signals and to the series-connection of a signal to the outputs of the interface which face towards the digital circuit part.
