Virtex-4中BRAM的频率是多少？

表39记录了这一点：DS302的Block RAM开关特性。
它的500MHz用于-12和400MHz用于-10

以下为原文

This is documented in Table 39: Block RAM Switching Characteristics of DS302.

Its 500MHz for a -12 and 400MHz for a -10

Don’t forget to reply, kudo, and accept as solution.

首先，感谢您的回答，然而，当我在XPOWER工具中定义工作频率以确定功耗时，该工具下载了BRAM automatique输出的工作频率。
即使我只定义了一个小于300MHz的频率值。



以下为原文

Firstly, thanks for your answer, however, when I define the working frequency in the tool XPOWER for mesuring the power consumption, the tool download the working frequency  of output of BRAM automatique. even though I define just only a value of frequency smaller than 300MHz.
