A timing based adaptive equalization circuit ( ) dynamically monitors a signal received at an input terminal ( ) and compensates for attenuation losses in the transmission of the signal by adjusting an equalization value that increases or decreases the equalization of the signal. A digital phase locked loop control circuit ( ) centers the transition of the equalized signal in a delay line circuit ( ). An analog delay locked loop circuit ( ) provides a fixed throughput time for matching delay elements of delay line circuits ( and ) in the adaptive equalization circuit ( ). Timing signals propagating in the delay line circuits ( and ) are stored in sampler circuits ( and ). The equalization value for equalizing the input signal is adjusted based on stored logic values of specific storage elements in the sampler circuits ( and ).

Adaptive equalization circuit and method

A computer implemented method for generating an integrated circuit design (11) is provided. A description of a circuit (16) is provided in a format such as a Hardware Description Language (12). A functional simulation (17) of the description is run to determine functionality of the circuit. A netlist conversion (18) converts the description to a netlist comprising both a single-ended and differential circuit. The netlist conversion (18) converts the description to a single-ended description (24), replaces single-ended cells with differential cells and interconnects the differential cells (25), and exchanges terminals of the differential cells to maintain logic equivalence (26). A simulation with timing (19) is run on the netlist to verify timing characteristics of the circuit. The netlist is then provided to a router to generate a physical circuit layout (20) having both single-ended and differential circuits.
