Abstract
A computer system is provided which includes a plurality of nodes, which include chips of different types. In each node, one of the chips is configured as a master chip, which is connected to one or more slave chips via two or more multi-drop nets (e.g., checkstop, clockrun). The master chip and the slave chips are connected to a reference clock, and event triggering information is transmitted via the multi-drop nets (checkstop, clockrun) to the slave chips. Event trigger commands are submitted by the master chip when it receives a request, and internal offset counters are used to adjust both the receiving cycle and the cycle when the command is propagated to the units on the chips. In operation, the offset counters are synchronized by a reference clock.
