Abstract: A circuit simulator includes at least one clock generator. The at least one clock generator is configured to generate at least one root clock signal for an associated clock domain part of the circuit under simulation. The circuit simulator also includes a clock modifier configured to generate at least one delay to be applied to at least one of the at least one root clock signal.

Abstract: A gas turbine is provided in which heat is removed from compressed air bled from the compressor section, for purposes of cooling in the turbine section, using a first heat exchanger to transfer heat from the cooling air to an intermediate fluid. The heat so removed is then returned to the cycle by transferring it from the intermediate fluid to a fluid to be injected into the combustion section, such as gaseous fuel or water for NOx control, using a second heat exchanger. A third heat exchanger may be used in conjunction with the second heat exchanger to control the temperature of the intermediate fluid and, hence, the temperature of the cooling air.
