Abstract
Circuits and a method for tuning an integrated circuit (IC) are disclosed. The IC includes multiple programmable fuses coupled to a control block. The programmable fuses used may be one-time programmable (OTP) fuses. The control block reads settings or data stored in the programmable fuses. A tuning circuit coupled to the control block receives the delay transmitted by the control block. The tuning circuit allows tuning of the IC without changes to the fabrication mask. The tuning circuit may include delay chains to provide additional delay to the IC when needed and the delay in the tuning circuit is configured based on the delay value stored in the programmable fuses and transmitted by the control block.
