XC4000 Logic Cell Array Family
Horizontal Longline Switching Characteristic Guidelines
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Since many internal timing parameters cannot be measured directly, they are derived from benchmark timing
patterns. The following guidelines reflect worst-case values over the recommended operating conditions. For more detailed, more
precise, and more up-to-date timing information, use the values provided by the XACT timing calculator and used in the simulator.

Description
TBUF driving a Horizontal Longline (L.L.)
Description
Global Signal Distribution
I going High or Low to L.L. going High or Low,
while T is Low, i.e. buffer is constantly active
I going Low to L.L. going from resistive pull-up
High to active Low, (TBUF configured as open drain)
T going Low to L.L. going from resistive pull-up or
floating High to active Low, (TBUF configured as
open drain or active buffer with I = Low)
T going High to TBUF going inactive, not driving L.L.
T going High to L.L. going from Low to High,
pulled up by a single resistor
T going High to L.L. going from Low to High,
pulled up by two resistors
From pad through primary buffer, to any clock K
From pad through secondary buffer, to any clock K
