FPGA Configuration - Is it possible to stop CCLK during configuration?


General Description:

The XC3000 devices were sensitive to the polarity of CCLK if they were stopped. Is this also true for Virtex devices?


No. The XC4000, Spartan/-II/-IIE/-3, and Virtex/-E/-II/-II Pro devices do not have the same sensitivity or restriction. You can start and stop CCLK at any point during configuration.
