XC4000XL Electrical Specifications
Definition of Terms
In the following tables, some specifications may be designated as Advance or Preliminary. These terms are defined as follows: Advance: Preliminary: Unmarked: Initial estimates based on simulation and/or extrapolation from other speed grades, devices, or devicefamilies. Values are subject to change. Use as estimates, not for production. Based on preliminary characterization. Further changes are not expected. Specifications not identified as either Advance or Preliminary are to be considered Final.
Except for pin-to-pin input and output parameters, the a.c. parameter delay specifications included in this document are derived from measuring internal test patterns.
