Virtex-II Pro Switching Characteristics
CLB Switching Characteristics
Delays originating at F/G inputs vary slightly according to the input used (see
are worst-case. Precise values are provided by the timing analyzer.

Notes:
1. A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
