Re: pci compliant devices?

[Stuart Adams <sja@brightstareng.com>]

 What I don't understand is how FPGA/CPLD's claim
 both PCI compliance as well as TTL, LVTTL, LVCMOS 
 compliance. PCI is reflected wave switched with the
 CLK->Q time (Tval) spec being the time from the 
 clock edge to Vstep/Vtest.
 
 This in contrast to TTL, LVTTL, LVCMOS in which 
 CLK->Q is the time from the clock edge to the output
 reaching Voh min or Vol max.

 For FPGA/CPLD's is seems that you just need to make
 sure you meet the PCI setup spec since the output
 driver is not relying on the reflected wave in order
 to reach Vih min.
