ABSTRACT:
One embodiment of the present invention sets forth a set of three building block circuits for designing a flexible timing generator for an integrated circuit. The first and second building blocks include delay elements that may be customized and fine-tuned prior to fabrication. The third building block may be tuned prior to fabrication as well as after fabrication. The three building blocks may be incorporated into a modular architecture, enabling designers to easily generate well-characterized, flexible, generic timer circuits.
