Abstract: A method for controlling at least two turbocompressors (1.1, 2.1), each having a control device (1.2, 2.2) for maintaining a distance relative to a surge limit curve (P1, P2) of the respective turbocompressor; wherein a first distance (A1.1, A2.1) is determined for each turbocompressor from its surge limit curve; wherein the distance to be maintained can be trimmed relative to this first distance in the control devices; and wherein the distance (A2.2) of a control device (2.2) to be maintained is trimmed relative to its first distance (A2.1) based on a trimming (A1.1→A1.2) of another control device (1.2) in such a way that a total process variable (dV/dt) remains substantially constant.

Abstract: A method and system for eliminating implementation timing with respect to a synchronization circuit. A standard library cell having a pair of clock input pins can be connected with at least two asynchronous clock domains of the synchronization circuit in order to measure a timing signal between the flip-flop latches crossing the asynchronous clock domain. A timing delay with respect to each bit pair of the asynchronous clock domain can be determined utilizing a static analysis approach during a layout phase in order to effectively synchronize the asynchronous clock domain. Each bit pair of the asynchronous clock domain can be checked via a static timing analysis tool in order to thereby improve functional accuracy of the synchronization circuit in a wide range of digital logic designs.

Abstract: A method and system for eliminating implementation timing with respect to a synchronization circuit. A standard library cell having a pair of dock input pins can be connected with at least two asynchronous dock domains of the synchronization circuit in order to measure a timing signal between the flip-flop latches crossing the asynchronous clock domain. A timing delay with respect to each bit pair of the asynchronous dock domain can be determined utilizing a static analysis approach during a layout phase in order to effectively synchronize the asynchronous dock domain. Each bit pair of the asynchronous dock domain can be checked via a static timing analysis tool in order to thereby improve functional accuracy of the synchronization circuit in a wide range of digital logic designs.
