新手对VHDL程序编写的一些问题
刚学VHDL语言,编了一段接收机的程序。想请问一下可以用一段程序实现上电复位功能的吗(不外加电路)?
还有就是出现了:
Warning: Timing Analysis does not support the analysis of latches as synchronous elements for the currently selected device family
不知道出了什么问题,要怎样解决?
Warning: Found pins functioning as undefined clocks and/or memory enables
Info: Assuming node "clk" is an undefined clock
Info: Assuming node "clk1" is an undefined clock
我的确是要clk,clk1两个时钟啊。其中clk是所提取的位同步信号,clk1是本地发生器的时钟信号,不知道到底要怎样定义这两个时钟啊? 路过,挣分....... 我也刚学VHDL 我也是刚开始学啊 好多都不懂啊~~~~哎~被催 在settings里面有clock的设置
