Virtex-6 -1L - Reduction in Configuration Timing Specifications

描述

The Virtex-6 FPGA Data Sheet: DC and Switching Characteristics (DS152 (v2.9) September 20, 2010 and earlier versions) contain timing information for configuration specification. The timing numbers outlined below will be updated in later versions of the Data Sheet. This is based on final characterization for the -1L parts and updates to these specifications will only affect the -1L parts. Only the timing specifications listed in the table below are affected and all other values in the data sheet still hold true.
