Abstract: An approach is provided to manage test transactors that interface with components of a hardware design. A first set of transactors is launched with the first set of transactors sending stimuli to various components that correspond to the first set of transactors. A manager receives signals when transactors of the first set have completed at which point a second set of transactors is identified that are dependent upon the first set transactors that completed. The second set of transactors is launched by the manager. The manager further facilitates transmission of data used by the various transactors. Transactors generate and provide stimuli to various components included in a hardware design, such as a System-on-a-Chip (SoC). Results from the hardware design are passed to the transactors which, in turn, pass the results back to the manager. In this manner, results from one transactor may be made available as input to another transactor.

Abstract: A system and method for synchronizing otherwise independent oscillators private to I2C Bus slave devices. An I2C Bus master device is capable of issuing two new general call commands, MEASURE PULSE and RESET PRESCALE. The I2C Bus slave devices respond to the MEASURE PULSE command by returning a digital count related to the number of ticks its local, private oscillator cycles through during a signal pulse on the I2C Bus. All such I2C Bus slave devices measure the same signal pulse on the I2C Bus, so the differences in the digital measurements returned during the MEASURE PULSE command are proportional to their respective oscillator frequencies. The various digital measurements returned are used to calculate appropriate oscillator prescale factors that will harmonize the final product frequencies of all of the local oscillators on all of the I2C Bus slave devices in the system.
