1. A method for adjustable delay calibration in a critical path monitor (CPM), the method comprising:
configuring, in an integrated circuit (IC), the CPM, wherein the IC includes a set of critical paths, wherein the CPM includes a set of split paths, a split path in the set of split paths corresponding to a critical path in the set of critical paths; configuring, in a first split path in the set of split paths, a first simulated delay section and a first fine delay section; configuring, in a second split path in the set of split paths, a second simulated delay section and a second fine delay section; configuring the first fine delay section such that a delay of the first fine delay section is adjustable in several steps; and configuring the second fine delay section such that a delay of the second fine delay section is adjustable in several steps, wherein the delay of the first fine delay section is adjustable differently from the delay of the second fine delay section in response to a common operating condition change, and wherein differently adjusting the delay of the first fine delay section and the delay of the second fine delay section causes an edge of a pulse to be synchronized between a first edge detector located after the first simulated delay section and a second edge detector located after the second simulated delay section. |
