    摘要: Embodiments herein present a method for automated simulation testbench generation for serializer/deserializer datapath systems. The method provides a database of transactors for generating and checking data within the datapath system, wherein the transactors are adaptable to arbitrary configurations of the datapath system. The database is provided with a single set of transactors per core. Next, the method automatically selects one set of transactors from the database for inclusion into the simulation testbenches. Following this, the method maps the first datapath and the second datapath through the datapath system by interconnecting the selected set of the transactors with the datapath system. The method further comprises setting control pins on the cores to facilitate propagation of the data through the cores of the datapath system. Subsequently, the control pins are traced to input ports and control registers.

    摘要: Thread entries are stored in a memory of the system to indicate executed instruction threads. Uses of processing resources by the respective instruction threads are detected and history entries for the threads are stored in a memory of the system. Such history entries indicate whether respective processing resources have been used by respective ones of the instruction threads. The history entries of first and second ones of the instruction threads are compared. The second instruction thread is selected for executing if the comparing indicates history of processing resources used by the first thread has a certain difference relative to history of processing resources used by the second thread.
