Generation of RST# at System Power Down
I'd like to know the typical methods for generation of the PCI signal RST#,
especially at the time a system is powered down. Section 4.3.2 of the PCI
Rev. 2.2 spec says that RST# must go active within 500 ns of the power rail
going out of specification. Is monitoring of the power rail and the
generation of the RST# signal typically performed by the power supply, or
by components on the motherboard? Is it done differently for CompactPCI?
Do typical desktop PCs really meet the 500 ns requirement? Can PCI output
buffers be damaged if RST# takes longer to become active at power-down?
