如何使用初始和readmem在FPGA中实现合成呢？

“但初始和readmemh都是不可合成的”
这不再是真的。
初始块可以为XST和Vivado合成，只需设置变量的初始值即可。
$ readmemh和$ readmemb也可以用于同一目的。

以下为原文

"But both initial and readmemh are non-synthesizable"
 
This is no longer true.  initial blocks are synthesizable for both XST and Vivado when all they do is set up the initial values of variables.  $readmemh and $readmemb are also synthesizable for the same purpose.

Vivado综合和XST支持初始化，为触发器，LUT和$ readmemh等任务提供INIT值，以初始化RAM内容。
在Vivado中合成RTL并检查INIT属性以了解行为。

Vivado synthesis and XST supports initialization to provide INIT values for flops, LUT and tasks like $readmemh to initialize the RAM content.
 
Synthesize the RTL in Vivado and check the INIT property to understand the behavior.
