See the timing measurement conditions in the PCI 2.2 Local Bus Specifications .
All PCI signals are measured from 0.5 × V DDIO of the rising edge of PCI_CLK_IN to 0.4 × V DDIO of the signal in question for
3.3-V PCI signaling levels.
For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.
Input timings are measured at the pin.
The reset assertion timing requirement for HRESET is in Table 19 and Figure 7
Figure 15 provides the AC test load for the PCI.
