Virtex-II - What is the CLKA -> CLKB clock-to-clock setup time of the block RAM (Tbccs)?


A value for Tbccs is specified in the data sheets for Virtex and Virtex-E devices. What is the value for the Virtex-II family? How do I calculate the value of Tbccs?


For an explanation of the "Tbccs" parameter, please see (Xilinx Answer 5894)


Tbccs is the same as the total block RAM minimum clock period (min pulse high + min pulse low) = (Tbpwh + Tbpwl).
