PCI System Timing Specification
Table 26
and
Table 27
list the critical PCI timing
parameters and the corresponding timing parameters
for the MX PCI-compliant devices.
PCI Models
Actel provides synthesizable VHDL and Verilog-HDL
models for a PCI Target interface, a PCI Target and
Target+DMA Master interface. Contact your Actel sales
representative for more details.

Notes:
1. T
OFF
is system dependent. MX PCI devices have 7.4 ns turn-off time, reflection is typically an additional 10 ns.
2. REQ# and GNT# are point-to-point signals and have different output valid delay and input setup times than do bussed signals.
GNT# has a setup of 10; REW# has a setup of 12.
